This time, I described the dream to my wife and son; he knows a lot about this stuff, and thought it was an accurate dream. It was possible. Now Sony is about to release the camera I was using in the dream.

Here is the dream.

I am walking across a kind of pier or boardwalk construction at the edge of water. It’s not in Britain. It’s warm and sunny, and it could be in the USA. The boards are raised above what would be the shore, and there are wooden buildings left and right of me. Ahead, I can see the lake water, and boat moorings with a jetty. To the left of me is the largest building, which is a shop or museum; something to visit. There are ornamental shrubs placed on planters or pots, and there are some notices or signs on the building. To the right, the wooden building is functional; it could be a boat house, a yacht club, or something like that. There are pine woods beyond.

My job is to move to the four corners of this scene, and other positions, taking care to make a complete set of images from a range of camera placements and angles. I’m using a wide-angle lens, and my camera is equipped with GPS which records the exact position and orientation of the camera for every shot.

I do not worry about people in the pictures because the software will ignore them, nor about the light, but it is a beautiful day anyway. I am taking the pictures for a project and this is paid work. This is actually what I do for a living (in the dream). I am visiting hundreds of the most frequently-photographed places in the world, and producing a set of pictures of each one.

But it’s not what I am doing which is the interesting bit. It’s what I know about it. In the dream, I have all the knowledge about what I am doing that I would have if it was real.

Time and space

Here’s how my pictures are being used. Each set of images with its GPS coordinates is fed into a system which constructs a 3D model of the environment. It is capable of recognising identical elements seen from different angles, and uses the GPS data to help identify them. With two 2D views of a building from different positions, it can use the focus distance and lens angle information to compensate for small inaccuracies in the GPS data, and wireframe the exact design and scale of the structure.

It identifies textures and objects like foliage, text on signs, clouds, and people. Once my entire set of images from this place has been processed (I am aware they are being transmitted as I take the pictures) new photographs which never existed can be created. A virtual camera can be positioned anywhere within the area I photographed, and my few dozen still images from fixed positions enable a new view to be constructed with complete accuracy.

I’ve used the result (in my dream) and it has incredibly high resolution because of the correlated image information. It’s a bit like Sony’s multi-shot or HDR or panorama technology, but instead of aligning two very similar images, it maps the coincident key points of entirely different views of the same scene. Where a walk-through VR allows viewing all angles from one position, this allows viewing any angle from any position.

And it goes beyond that to add a timeline.

The system I’m working for gathers millions of photographs from people all over the world. I’m photographing these key locations because they are the most photographed in the world. Camera phone images now record GPS data, and also record the date. So (at this future time) do most digital cameras and video cameras.

The system can find images matching every location by trawling the web; from Flickr, Facebook or whatever is out there. It can analyse the images to see whether they actually match the location they appear to be from. For every location, the system gathers in as many more pictures as it can find.

The first result of this is more detail. The second is that the viewer can change the season or weather conditions in which the location is seen. It can be viewed at night, in snow, in rain, at sunset; whatever. My image-set provides the framework, but seasonal changes can be created from the ‘found’ images of the place.

The second result is the timeline. Old photographs of these places have been fed into the system. For some popular spots, it’s possible to track the environment backwards for over 100 years. Trees change size, buildings appear and disappear. By turning on ‘people’ (which the software can remove) the crowds, groups or individuals who were in the scene at any time can be shown. And the 3D environment is still enabled because all the old photographs are co-ordinate mapped to the new information.

I do not have to work all this out in my dream, because I already know it. I am working with this awareness. The entire thing is known to me, without having to think about it. I also know that future pictures captured from internet will continue to add to the timeline and the ‘people’ function, so in five years’ time the seasons and the visitors to this place can be viewed almost by the minute.

The dark side

Because this is a dream, I do not have to think or rationalise to get this understanding; it was included with the dream. As I wake up, I realise what I have been dreaming and then make an effort to ‘save to memory’. That also kicks in the thinking process.

I start to wonder who was hiring me to do this survey-type photography, because in the dream that is one thing I don’t know. I realise how exciting it is to be able to use this Google-Earth or Google-Street type application to view not only any part and any angle of these tourist locations, but any season or time of day, and many past times in their history.

When I describe it to him, Richard suggests it’s probably Microsoft. He likes the collation of web-sourced images covering seasons, and maybe decades of past time. He thinks it is all possible and the core technology exists right now. I should patent it and give it a name!

But there is one thing which I understood just as I was waking up; the system can recognise people. Not just as people to be ‘removed’ from a scene or turned back on; it can recognise faces. The movements of one individual can be reconstructed within that location, and it can use a ‘cloud’ of gathered pictures taken at the same time to do so. This is not just virtual tourism and virtual history. In other locations – not beautiful waterside boardwalk quays – it is surveillance brought to a new level.

Sony A55 and A580

Sony’s new models with built-in GPS are the first cameras which will record the data my dream required. The GPS is not the typical latitude-longitude only. It also records height above sea level (elevation) and the direction the camera is pointing (orientation). The camera-data information records the focus distance and point of focus, and the angle of view of the lens (focal length), the time, and the measured light level and apparent colour temperature. Maybe in the A55 the spirit level function also records horizon tilt and position.

OK, the camera I was using in the dream was more like a 5 x 4 on a tripod. But that could be just a dream – like the giant fish which leapt on to boards and brought the jetty crashing down into the water a second before I woke up…

So, I copied my ramblings and moved them here, instead of putting them in a forum post where just a few hundred people would see them. Tens of thousands of visitors see Photoclubalpha’s main site articles, and I want this to be seen, because it matters.

PP’s write-up is very positive – it is not a ‘bad review’ in that sense – but much of the wording used is misleading, and omissions can sometimes distort the comparison a reader makes.

PP starts off by saying the NEX-5 has ‘the added advantage of HD video’ over the NEX-3 – of course, both have HD video, the NEX-5 is 1080/50i AVCHD while the NEX-3 is 720/25p MPEG4. It could be assumed that the PP reader has only a marginal interest in video, but this phrasing does not describe the feature and implies that the NEX-3 lacks HD video.

The screen is great for ‘low level composure’  and the APS-C sensor is ‘ideally placed for delivering DSLR quality images’.

The majority of the selecting, PP says, is done through ‘never get lost’ menus (sounds as if PP were fed a marketing term here – I would probably call some of them ‘dead end’ menus in maze terms – you have to return or exit). Confusingly, PP says there is ‘no dual sensor cleaning, but there is an electromagnetic vibration system and an anti-static coating on the sensor’. I thought this was a dual anti-dust measure. What is ‘dual sensor cleaning’ if it’s not this, and how does the NEX lack it?

PP also says that removing the lens reveals how close to the rear element the chip sits inside the camera, and states: ‘There are potential issues here, as this may cause image quality problems such as distortion and aberration’. Well, that’s just completely untrue and gives readers needless doubts. Some of the lowest distortion wideangles ever made have had very short clearance back focus, like the 21mm Super Angulon for Leica M or the classic 21mms designed for mirror lock-up by Nikon and Minolta – or the 16mm Zeiss Hologon for Contax G.

Some of the world’s best lens designs have used rear elements almost touching the film, including the Ricoh GR (for film), the Minolta TC-1; and the excellent Sony R-1 Carl Zeiss zoom also features a minimal gap between its rear element and the 1.7X sensor of that camera, the absence of a mirror freeing Zeiss to create one of the best 24-120mm equivalent zooms ever designed.

In fact the 18mm mount to sensor distance and the wide mount throat combine to offer the maximum possible scope for the makers to design distortion and aberration free lenses of a quality hard to achieve without high costs and large size, heavy weight even for APS-C DSLRs. PP has got it exactly the wrong way round. They have turned a huge positive aspect of the camera into a negative niggle.

Sweep Panorama is described as a function which is ‘not new on a Sony camera’. Actually, this type of Sweep Panorama is entirely new on a Sony, or any camera. This is not a video-composed Sweep Pan, as found on all previous Sony and other compacts. It is a high resolution, auto-stitched, multi-shot panorama of unprecedented size (up to 23 megapixels).

Confusing the issue, PP states that the panorama files are playable on a Sony Bravia 3D TV. This is incorrect. Normal sweep pan (.JPG) files are playable on any HD TV, and are not 3D. The camera(s) have a second entirely separate Sweep Pan 3D mode, which is not a sequence of shots, but a video pan like compacts. The file (.MOT) created is 1080p HD in height, and in a 3D format; and it can be played back on most 3D TVs using the same system as Sony Bravia.

Most of PP’s comments on using the camera are fair and balanced descriptions of its strengths and weaknesses, but once again, language gets in the way of accuracy. The ‘large optics help deliver… detail to the sensor’. What does that mean? Which large optics? The lenses are fairly small. Their size has no bearing on how much detail they ‘deliver’.

‘This is not the fastest camera out there, but with speed priority engaged it’s impressive at 7fps’ – well, actually, it IS the fastest CLC/ILC out there, and that 7fps has no competition from Micro 4/3rds, Samsung NX or Ricoh. The 2.3fps standard capture rate includes reliable AF tracking (certainly not guaranteed when shooting continuous action with the competitors), but this is not mentioned. It would be fair to comment on 2.3fps being a modest drive rate, but the continuous AF performance had to be taken into account when doing so.

‘The general consensus of opinion is that CSC cameras are effectively high quality compacts that deliver DSLR quality. Yet the NEX-5 is still rather bulky and certainly not pocket material’ - conclusion.

‘The NEX-5 takes the compact size of these CSC models down to a new level, as it’s the smallest and lightest of these removable lens models to date’ - second paragraph of the main report, and highlighted pullquote.

I don’t think I need to point out the conflict in these statements. And the day before writing this, I had the NEX-3 with 16mm lens in my shirt pocket.

‘The HDR mode is okay, but it’s not as good as true HDR creation using post-production software’ – not the best comment to make on the most advanced, 6EV range, in-camera HDR system yet seen and one which also saves a non-HDR JPEG of the normal exposure (not mentioned). None of the other multi-shot modes gets mentioned at all; no reference to the Anti Motion Blur or Twilight modes which blend several exposures to create one low-noise, sharp result.

Finally – ‘Most of the CSC products are quite similar in price, especially with lenses that cover the same focal lengths’. Actually, they are not quite similar in price. To get HD 1080/50i you have to spend almost twice as much. To get their equivalent of the 16mm lens… sorry, you can’t.

There is no 12mm f/2.8 pancake lens made for Micro 4/3rds, or any 16mm prime for APS-C. The 17mm offered by Olympus is a 34mm lens equivalent, not a 24mm equivalent. The 20mm offered by Panasonic is a 40mm equivalent. The 30mm from Samsung is a 45mm equivalent.

By glossing over such issues or ignoring them entirely, the PP report omits most of the unique selling (and using) points of the NEX, and the reader is left to assume that it’s pretty much the same as the competition.

I believe the job of a review is to highlight all the aspects of a product which may not be understood fully by the reader, because they are new or unfamiliar; to point out the differences between products, because these differences drive buying decisions. A single feature on a new camera may be the one feature which attracts many buyers. Sometimes, this matters more to the buyer than all other aspects of handling and design. Single features can persuade photographers to change their entire camera system. Just look at Nikon with ultra-high ISO in the D3/3S – or Canon with true 1080p in the 5D MkII, 7D and 550D.

For me, 1080/50i video with stereo sound is important as the only other way to get that in an affordable package is the Canon 550D with external microphone, or the Panasonic Lumix GH1 at around 60% higher cost. The 16mm lens is important – there has never been a 5-element f/2.8 design covering this angle before. The E-mount is important, it allows more potential choice of adaptation to other optical systems (lenses, scientific, astro, micro, you name it) than any other mount. I’ve already ordered my Sony Alpha adaptor (mentioned briefly by PP without further details or comment), plus independent versions for Minolta SR/MD, Leica M39 and C-mount.

APS-C is important too, as this 14.2 megapixel sensor offers the best quality and largest image size in its class.

The PP Overall Conclusion

Ultimately, PP’s Overall Conclusion certainly fits the report, because so much is omitted which would engage and interest their readership, and so much is dwelled on with makes the NEX seem nothing all that different:

‘I wouldn’t recommend the NEX-5 to the more discerning user’, says Darren Harbar while giving the camera 8/10, ‘but for someone who wants a creative point-and-shoot that will give some control without added complication, the NEX-5 is perfect’.

The build quality, design of the lenses, availability of fisheye and ultrawide converters, battery life (or otherwise!), JPEG quality, and many other aspects are not touched on at all in the PP report. Some of these might be negative – battery life can be short, batteries are expensive. Others might be positive – no other system made offers the option of a 12mm (18mm equivalent) wide angle or 10.2mm (15mm equivalent) fisheye at such low cost.

Is ‘I wouldn’t recommend the NEX-5 to the more discerning user’ a damaging conclusion?

PP is certainly not alone in thinking this, but it’s something which should not be said unless you can qualify it by revealing what you would recommend to the ‘more discerning’ user. Think about the language again; above all, it’s the language of the PP report which will colour the readers’ opinions. What does ‘more discerning user’ actually mean?

As it happens, I’m a fairly discerning user; I can tell the difference between the qualities and capabilities of the many cameras I use, I am capable of making judgments, I have the ability to compare and make choices. I can pick the right tool from the rack. Sometimes, I do want a point-and-shoot that will give some control with added complication, just like PP says.

As it also happens, I want a point-and-shoot which can capture high quality 1080 Full HD video  (preferably 24-25-30p, but 50i will do) with excellent quality sound; I want more than 12 megapixels for stills, 14 is fine, 18 would be even better; and if anyone had put a list of possible lenses in front of me, a 24mm f/2.8 equivalent would have been ticked without hesitation.

It was the lens I could never get, or afford, for Leica; it was my favourite fixed focal length in manual focus SLR from the moment such lenses became available around 1974. 24mm f/2.8 was one reason I dumped the Pentax system and bought into Minolta back then; it was the first lens after the 35-70mm f/4 ‘kit’ and the 50mm f/1.7 that I bought for the Minolta AF system in 1985. 24mm wide reach was the reason I pre-ordered the Carl Zeiss 16-80mm for my Alpha 100 in 2006, and it’s the reason I like the Nikon 16-85mm and the Canon 15-85mm best of all the kit zooms for those systems. It’s even the reason I use a vintage 1999 24-85mm Minolta lens on my Alpha 900.

My conclusion

My NEX-5 with 16mm and 18-55mm OSS lenses cost me £679, but that price included a free stereo microphone which sells everywhere for £99. The built-in mics are so good I might not need it (the camera can record clean sound even if placed just a metre away from a PA speaker blasting out live music – try it with a Nikon D5000 or a Canon 550D). But it makes the two-lens kit cost a ‘real’ £580.

‘Worth the asking price’ is PP’s comment. Worth? It’s the bargain of the year, and that is at launch prices which inevitably fall later on. If you want the wide-angle capability, it’s on its own, and if you prefer the angle of a 28mm-equivalent view, you have 14 megapixels to be cropped down and still match the pixel count of Micro 4/3rds.

NEX has real weakness if you are looking for telephoto reach, and many point-and-shoot upgraders will have been used to surprising long lens equivalents; 300mm is nothing. Micro 4/3rds can get you to to that 300mm equivalent in a similarly priced kit, though without the same wide-angle end. This would have been a useful and valid point for the PP review to raise, of value to readers; don’t buy NEX if you are into safari parks, garden birds, or next door’s bedroom windows. When the 18-200mm OSS does arrive it will cost more than a complete Olympus kit with E-PL1, 14-42mm and 40-150mm – it is also a VERY large lens. There is no neat little 55-200mm OSS for NEX, as there is for Alpha, Nikon and pretty much every interchangeable lens system made whether CLC or DSLR.

Every time I use the NEX-5 I find points to criticise. That rear jog wheel has a tendency to change my selected A mode aperture setting when I pop the camera into the small bag I’m using, forgetting to turn it off first. There I am shooting at f/6.3 and the next time I use the camera it’s at f/22. I wish I could tilt the screen vertically, not just horizontally; I love the screen on my Nikon D5000, and the NEX would have been so much better with the D5000′s design. You could even have turned it to face the camera, protecting the screen and removing distracting displays when using the 16mm optical viewfinder. But no, it’s like the A350-550 series, and fairly limited by its hinged articulation.

When reviewers pick up on points like this, it helps the camera makers. In a magazine like PP, hugely influential, such observations can change the course of future camera design for the better. I don’t find a single observation in the Practical Photography August 2010 issue review of the NEX-5 which stems from the critically aware experience of using the camera or treads the risky ground of daring to compare it directly with competitors.

The free download from the Sony Europe support site (http://support.sony-europe.com/dime/DSLR/DSLR.aspx) adds several performance enhancements including 3D Sweep Panorama. This exciting new technology means it is now possible for consumers to capture dramatic panoramic images in 3D, all with an extra-wide field of view.

3D Sweep Panorama is simple to use; activated simply by pressing the shutter button and sweeping the camera from one side to the other. The NEX-5 and NEX-3 shoot a high-speed burst of frames that are automatically combined inside the camera to create a seamless panoramic still image containing depth information. Sweep Panoramas can be enjoyed in 3D when the camera is connected to a 3D BRAVIA or any standards-compatible 3D TV.

The update also offers other enhancements for the NEX-5/NEX-3. These include:
· Improvement of ‘normal’ 2D Sweep Panorama shooting;
· Decreased power drain when the camera is switched off;
· Quicker start-up in low-light conditions.

The update is only needed for NEX-5/NEX-3 cameras with Version 01 firmware currently installed. Cameras shipped with Version 02 firmware or higher are already updated with the new features. Owners can find out what firmware version they’re currently running by selecting [MENU]/[SETUP]/[VERSION]. NEX-5/NEX-3 owners who have registered their product with Sony will be advised of the update via email.

*System requirements [PC]: Windows XP SP3 (64-bit and Starter editions not supported); Windows Vista SP2 (Starter edition not supported); Windows 7
[PC/Mac] Hard disk space: min. 200MB / RAM: min. 512MB.
Upgrade requires USB cable connection between computer and NEX-5/NEX-3.

Editor’s comment: there is no reference to any improvement in Alpha mount adaptor performance, or the addition of other functions that have been requested from the launch day onwards such as remote flash triggering, interface changes or reassignment of button functions, manual microphone gain control. There are two firmware files in the NEX, one for the BODY and one for the LENS/MOUNT ADAPTOR. This upgrade leaves the LENS/MOUNT ADAPTOR firmware version still at 1.0, only the BODY is upgraded to 2.0.

This software is region-specific. Do not install the European upgrade on any other than a PAL 25/50 European market NEX. There are similar upgrades now on the Japanese and US sites.

WARNING: this is a pretty clunky PC-0nly upgrade method. There is no Mac version, and it does not work by copying files to a memory card – it works only by running an .exe installer on a PC (and not every PC either, see above, and not Macs despite their reference to Mac in the press info). I had not used my netbook for three weeks, and I had not connected the NEX to it before, with the result that the installation process was hampered by constant pop-ups windows including a string of demands from Norton that I pay for their anti-virus software (I’d rather chuck the netbook off a bridge, and intend to find out how to clear this rubbish off the system for good), and a Windows XP update to handle the ‘new device’ it had detected (the camera). Some of these windows were modal dialogs and could not be closed without action, or moved to the back of the installer window. So, before installing, first let your PC do its dance with Windows updates, Norton and any other intrusive processes – or turn off your internet connection entirely to prevent interruption. But, if you have just acquired a new NEX and wish to upgrade it, first connect the camera normally and let the PC install its un-necessary ‘drivers’ if it thinks it really needs them (the NEX conforms perfectly to USB Mass Storage, and in fact the PC does not need anything installing or updating).

Overall marks for friendliness and functionality: around 5 out of 10. It works, but the instructions do not include any warnings about the potential for disruptive behaviour from your PC during the process.

This will have many Alpha system stalwarts saying ‘Help!’ in their own right, as they are still waiting for the predicted arrival of the real new Alphas, the 700 replacement with HD video and its 500-series sibling. What they did not expect was to find two entry-level models arriving without video, and with the changes restricted to a Tale of Peter Rabbit - they lost their buttons while squeezing under the fence to get into the point’n'shoot upgraders garden.*

But actually it’s good news, because it’s a garden full of cabbages who will appreciate the simplified interface and button layout. And they get a very high quality carrot in the form of that 14.2 megapixel sensor, as this looks to be Sony’s standard pixel count for all cameras at this level and higher. If 14.2 is entry level, a denser sensor must surely be on the way for a midrange/semipro APS-C model soon.

It’s presumably the same 14.2 megapixel CCD sensor as found in the Alpha 380, with its ISO 100-3200 range and 2.5fps continuous capture. On Dyxum’s forum, there is speculation that processing will be improved.

The 290 has a plain fixed screen, the 390 has a tilting screen and Quick AF live view (the in-prism system using phase detection). Both have chunkier and better shaped handgrips than earlier models, perhaps in reponse to criticism of ever smaller handling profiles. Thy at least have the same eyestart sensor arrangement as normal and do not copy the 450, which has the sensors above the eyepiece instead of below, and makes for a very awkward camera to use.

They keep exactly the same AF sensor, metering system, shutter, flash system and in-body SSS image stabilisation as previous models. The pop-up flash is GN10, the battery life is around 500 shots (230 in Quick AF Live View mode). The A290 weighs only 456 grams.

And the 290 has not a button in sight on top, even the shutter release and on/off switch have been shifted forward leaving a clear top panel. It’s rather like seeing Botticelli’s Venus without a navel. However, the shutter release placement of the last series was a major criticism, and this new position restores a more ‘industry standard’ placing as used by Nikon and Canon, and by Sony in the A450/500/550 series.

That rather impressively compact lens, by the way, is the 75-300mm Sony SAL seen in a neatly compressed perspective, not something new you don’t know about. And that tells us the cameras do have screw drive AF (fears in certain forums unfounded).

After asking ‘What’s NEX?’ we have the answer – mainstream Alpha DSLRs using the same software based type of virtual-controls interface as NEX, with the same level of built-in guidance for new users. All the functions of their predecessors are still there, if not so obvious camera users with experience of traditional controls.

Instead, you get ‘colourful on-screen icons’ though no claim is made in the press announcement that Sony Ericsson mobile phone designers were involved (as they were for the NEX interface). Lens options include the 18-55mm SAM and a twin lens kit with the 55-200mm SAM added.

The press and technical data does not clarify whether the card drive is the same dual format single slot used by NEX (replacing the twin slot drive SD/MS Pro Duo of earlier models) or what type of battery is used. There is no mention at all of wired cable release, but ‘Remote Commander’ remains as a feature (the infrared controller, sold separately). And there is no mention in the specifications of wireless remote flash, either, though it is included – nor of features like DRO+. There’s still an AC mains adaptor socket.

Premium features such as HDR multi-shot blending, found on the 4-5xx series, have not been added to these models.

* I should point out that Peter Rabbit lost his buttons getting OUT of the garden, after eating too many lettuces. But Sony is clever and realises that to get INTO the consumer market garden faster, you might as well lose the buttons first. If you ever need to get out, well, you lost more than buttons…

The European press launch

David Kilpatrick recorded the proceedings at Le Meridien Lav Hotel, Split, Croatia on March 11th 2010 using a Zoom H2 portable digital recorder. Shirley Kilpatrick transcribed the audio, with subsequent editing to translate verbal output to read well as text. This is a multi-page document please use the PAGE navigation at the foot of each page to continue reading. It is a very long document.

Nick Sharples, director of corporate communications for Sony, Europe, welcomed the press to Split in Croatia, and thanked everyone for getting up before breakfast – especially those from Portugal who arrived at midnight (volcanic ash delayed their flights). The launch was synchronised round the world, hence the 8.00am timing for the European meeting.

Yoshiyuki Mogami (Vice President of Digital Imaging, Europe) was introduced to explain a little bit more about the business strategy for Digital Imaging in Europe. Yoshiyuki thanked everyone for coming over to Split; the team from Munich had arrived by driving ten hours.

Sony started Alpha business in 2006, he said, introducing the Alpha 100 in Morocco. The Alpha 700 was launched in Italy in 2007, the Alpha 900 flagship model was introduced in Scotland in 2008. “We have carried out surveys asking people in Europe which brands they would think of when buying a digital camera; the figure has risen from 50%, to close to 70%. Now we are enjoying a 15% market share in Europe. This figure is OK, but Sony now really has to go to our next step.

“But looking at the DSLR as an industry it’s not like two years ago or three years ago. DSLRs were pretty much a booming industry, and that’s why everybody came into his segment. These days the growth of this segment has very much flattened, and of course you could say this is due to economic slow down or recession, but we suspect that the traditional DSLR has a limit in mass appeal to consumers.

“So that’s why Sony can try to break this type of barrier. We put together all kinds of voices and views on this technology to see what we can do – we think we have heard the customers’ voice, and really put it into this project.”

Mogami-san introduced Toru Katsumoto, senior general manager of Alpha:

“Today I would like to officially announce our new ultracompact interchangeable lens camera we have already shown at PMA in February and in Japan. In the current market the boundaries between the three categories – DSLR, compact still camera and camcorder – are already starting to merge.

“In the area when DSLR and Digital Still Compact merge, we see great possibilities. Let me introduce to you NEX-5 (he holds up the camera, in front of large projected images of the cameras). This beautifully crafted body is designed to bring out the presence of the lens. The body is so slim and compact but without sacrificing any size or balance. The grip on this camera ensures a firm and comfortable hold despite such a slim and compact body. The rigidity and texture of magnesium alloy gives a high grade appearance and solid feel to the camera.

“NEX-3 is designed for a more casual approach, and can be very attractive especially for those who have yet to explore the world of the DSLR. The slim design comes in three different colour variations, with a unique texture on the grip. It simply feels great in one’s hand in addition to being a stylish camera.

“The key concept of NEX-5 and NEX-3 is to combine the best of both worlds – the image quality and power of expression of the DSLR, with the portability and ultra-compact design of a digital compact camera. We strongly believe that NEX-5 and NEX-3 are cameras that are capable of satisfying customers’ needs from both DSC and DSLR segments. Namely, compact digital still camera users who are motivated to step up from DSC, and DSLR users who are demanding a more compact camera without compromising DSLR power.

“Professional quality in your pocket is the buzzword for this camera. There are six elements:

• DSLR quality in still and moving images
• Compact and stylish
• Power of expression derived from interchangeable lenses
• Making creative work easier
• Beautiful high definition movies easily filmed
• High speed continuous shooting, 7fps

“The APS-C sensor successfully packs DSLR quality in a small body (he removes the lens and shows the sensor). The new sensor is significantly larger than the FourThirds sensor, resulting in a higher pixel count and superior picture quality.

“Our designers have done a great job; the philosophy is a minimalist design. The lens itself is small, but the body size is so small that the lens looks dominant overall. With the pancake lens, it comes close to the size of a point and shoot camera. It is the world’s smallest, and is lighter than either of the rival brands (Olympus and Panasonic profiles shown on screen but not named).

“The depth of the flange back on the camera is 18mm, the world’s thinnest. This is why we can make it so slim. There are three new lenses. Also conventional Alpha A-mount lenses, currently in customers’ hands, can be used via our mount adaptor.”

Katsumoto-san described the user interface with its virtual scroll wheel, adjusting depth of field; and the sweep panorama including the 3D function. “During the sweep motion, the camera generates two pictures, one for the right eye and the other for the left. You do not need two lenses for 3D.”

He said that Handycam experience had been used to set up high definition recording. Toru emphasised the value of Alpha NEX division working together with other Sony technologists.

“NEX-5 and NEX-3 are only the first two products to be offered by Sony in this emerging area. We believe that products based on the combination of a large imaging sensor and interchangeable lenses are not limited to NEX-5 and NEX-3; today, let me take the opportunity to reveal our second proposal to you briefly. As I am speaking now, a dedicated group of engineers is in the process of developing a new camcorder with the interchangeable lens system (he shows a mockup image).

“This camcorder will come with an EXMOR HD APS-C sensor for DSLR quality video in AVCHD form. Like the NEX-5 and NEX-3, with an adaptor, this new camcorder is also compatible with current Alpha lenses allowing videographers to access a wide range of high performance lenses to be used to express one’s creativity like never before.

“Needless to say, its body design is specially optimised for video shooting. Details of this product will be communicated soon, I’d say around the Autumn area, so please stay tuned. The combination of a large image sensor and interchangeable lenses can create whole new dimensions and expression and possibilities.

“To express our strength in such products, we would like to introduce the phrase “Beyond Our Eyes” which contains the following meanings – bringing new experiences, and style of unforeseen dimensions, that evoke deep emotions, and creating a visual world beyond how our eyes can see in both still photography and video.”

After this, the conference was officially over, and journalists were asked to re-convene for region specific in depth meetings. The meeting for the UK and Scandinavia was headed by Paul Genge of Sony UK. See next page.

The Leica M and screw mounts, with under 1mm difference between them, are 10mm greater than this at around 28mm. Screw mount Leica lenses can be adapted to M even though there is only 1mm difference. With 10mm difference, almost any lens ever made for any camera – even the Robot system, original Contax, maybe even the Pentax 110 SLR – can probably be adapted to fit the E-mount. In fact it will accept 16mm and 35mm (half-frame) ciné, C-mount CCTV lenses, and subminiature camera lenses.

You name it, the NEX will be able to do it. Telescopes, microscopes, endoscopes, whatever. And Alpha lenses, and MD lenses. There is even enough ROOM with over 25mm the spare to fit a true retrofocus format reduction converter – that is, a 0.66X optical unit which condenses the image from a full frame lens to fit the APS-C sensor. It is already done in the video and ciné world, and these converters have a wonderful bonus. Your 24-70mm f/2.8 SSM lens becomes, with a 0.66X reducing converter behind it, a 16-46mm f/2. That’s right – the same way a teleconverter loses you a stop or two, a format reduction converter gains you a stop.

The same converters also increase resolution, much as teleconverters reduce it. Zeiss can achieve 400 line pairs per millimetre from high grade 35mm format movie lenses when rear-converted to reduce on to 16mm or video.

Will Sony ever make such a converter? Do they even know that Zeiss have designs, and make exactly this type of converter for Arriflex and other systems via Angenieux? Do they realise that rear fitting format-reduction converters can also perform an AF function, allowing a manual focus lens from Nikon, Canon, Contax, Minolta or whoever to be mounted on a converter which has an ultrasonic AF mechanism of its own?

Imagine that – your 50mm f/1.2 Rokkor becomes an autofocus 33mm f/1.0 on the NEX. This is not blue sky thinking, it’s an optical practicality not a mere possibility. However, you don’t want to know the price of Zeiss converters, and for a system like NEX a universal converter might never be possible; it might have to be matched to the prime lens.

The NEX mount is almost as wide in the throat as an SLR mount; for some obscure reason, Sony chose to measure the outer diameter of the flange, which is not what matters, and came up with 62.6mm for the Alpha and 58.9mm for the NEX. Inner diameter of the bayonet, the bit which counts, was not stated. But it’s a wide throat and can cope with a huge potential range of adapted lenses.

Less of this ramble, and on to the plain vanilla – the camera.

Inside the camera there is a 14.2 megapixel CMOS sensor, capable of HD video and of course the vital live view and contrast-detection focusing on which the entire camera is based. This is fed to a 3 inch, 920,000 pixel TruBlack articulated rear screen and the user must compose, control and review everything on this screen. There are few buttons, no dials except a single control wheel, and everything is converted to a virtual control or a menu choice using a Sony-Ericsson developed graphical user interface.

The NEX5 camera, by some way the preferable model of the two, has a magnesium alloy body which matches the machined and brushed aluminium barrels of the lenses. It comes complete with a tiny camera-powered flashgun, screwed into an accessory slot on the camera top which has more contacts than a mere flash should need. Three, at least, must be for the stereo microphone audio interface which also draws Electret Condensor Microphone phantom power from the body’s battery.

At the end of less than 24 hours with the camera, I cleaned the white table on the hotel balcony and took a few pictures which will show you the camera in detail.

Here, you can see the 18-55mm f/3.5-5.6 OSS (stabilised) kit lens to the left; the camera body is fitted with the (raised) flash and the 16mm f/2.8 E-mount non stabilised wide angle pancake lens. In front is a 49mm fit lens cap (for either), InfoLithium battery good for around 350 shots, a 4GB MemoryStick Pro Duo MkII, and the lens hood for the 18-55mm.

The NEX baseplate view reveals the steel tripod bush set into the mag alloy casing, the lens release in a slightly unfamiliar position, the size of the grip and the location of the new Sony factory making this system – in Thailand. It was rumoured that these lenses would be branded as Zeiss. Having used these two, I can’t say they would ever have deserved that. Both are very sharp centrally but pretty soft at the edges unless well stopped down, and both have fairly strong CA. The central sharpness is excellent, about as good as you could expect, perhaps aided by the Contrast Detect focusing which is entirely free of back or front focus.

Here’s the body, which is 24.2mm thick at its thinnest point, with the lens removed – the sensor is exposed. But that’s how it normally is, whether switched on or off. Turning the camera off does not closed the focal plane shutter (30s to 1/4000th, X at 1/160th, vertical travel). Dust removal is not going to be all that easy with the sensor cover glass sitting so well shielded and recessed behind the shutter gate. When a lens is fitted, the sun can come in and focus itself on the sensor. What issues will that cause for anyone careless enough to leave a NEX with a 16mm f/2.8 lens on its back, with no lenscap, in tropical mid-day sun? As people sometimes do, dining or drinking outdoors?

The lens will afford some protection when fitted. The well-machined metal mount should not admit dust too easily. There are ten contacts on the E-mount lenses (note the legend ‘E-mount’ etched on the flange). They transfer EXIF information about the lens, power for the ultrasonic focusing motor which is a silent ring type, power for the aperture adjustment via a stepper motor, and command and feedback signals to make these adjustments. Enough of the protocol is shared for the E to A mount adaptor LA-EA1 to have been designed to operate SSM and SAM Alpha lenses. At the launch conference, Sony admitted their engineers had failed to get reliable focusing, so AF was disabled in firmware. They hoped that a firmware update would restore the planned AF functionality with in-lens motor Alpha glass.

The ability to change aperture during video shooting is only offered with E-mount lenses, and is disabled when A-mount lenses are fitted via the adaptor. Sony does not make it clear whether different apertures can still be preset, before filming.

This is one of the lenses which might have proved interesting on the NEX – the Sony SAM 30mm f/2.8 1:1 Macro. You can see the difference in scale and engineering approach. Note the AF/MF switch on the SAM lens – it’s the only way to over-ride AF on the Alpha bodies. The E-mount lenses are far superior, they have full time manual focus over-ride which is ultra smooth, just turn the focus ring at any time to shift away from the autofocused point. When you do this, the rear screen instantly and automatically switches to an enlarged view to aid manual fine focusing.

Here’s a close-up of the 16mm lens iris. Whatever shape of aperture is claimed, there are only seven blades (probably to keep the action very light) and that minimum f/22 does not look especially circular to me – much like any other lens with a very small iris diaphragm. The blades are oddly asymmetrical too.

Here you have the 18-55mm naked on the body. It’s a really good cosmetic match but you can see how large even this lens is compared to the camera. The 18-200mm f/3.5-6.3 which was not ready to be tried out is even larger. Note the position of the strap lug(s). They are placed down the body and angled so that when neckdangled or shoulderslung, the camera tends to hang with the lens aiming down and the screen facing up. This saves a lot of screen scuffing, gives quick access to the info there presented, and keeps the bigger lenses neatly placed.

Be warned, though, that you can’t expect to grab a shot from hanging position. If the camera is turned off, it takes a short delay to fire up and for the screen to brighten as the gain is adjusted (always from dark). If the camera is sleeping, first touch on the shutter button does the same, with the screen ready for use in a second or so. Then a firmer pressure acquires focus and re-adjusts the screen exposure; AF officially takes 0.3s, but I found you could easily have 2-3 seconds from the moment of raising the camera to being able to fire the shutter in confidence. I actually think my old Konica Minolta Dimage A2 is faster. I missed several candids and moving subjects when testing the NEX5.

This is just a shot with the petal lens hood fitted. You may notice that the 16mm lens, supplied without a hood, does have a bayonet as well as a 49mm filter thread. This is to enable two afocal front lens convertors to be fitted – the VCL-ECU1 is a 0.75X rectilinear converter, turning the 16mm into a 12mm ultrawide, while the VCL-ECF1 is a 0.62X fisheye converter creating a 10mm full frame curved view fisheye. Given that the 16mm is expected to be only around £200 (or much less in effect when bought with a body), and these converters are £100 and £120 respectively, a system will be no great weight on the pocket.

There is also an optical finder for the 16mm, which occupies the flash/mic shoe, and will cost £130. Eh?

Like the flash, shown above, it will use the 12-pin gold plated connector and thumbscrew to attach. But it’s not an electronic finder. No-one would answer whether this contact array will support an EVF attachment.

This is how you secure the flash, which stows by folding down flat. Raising it, as in this shot, turns it on.

This runs off the battery, which lives next to the dual-purpose card slot. Previous models have had twin slots. The NEX range uses a dual MSPro/SD slot which auto senses the type of card being used. An AC mains adaptor is available which uses a dummy battery and a cable emerging through a hinged portal in the battery door (above).

The rear screen is articulated very much like the Alpha 550, and does not turn to face forwards, or orient itself in any way to suit vertical compositions. It is very much geared to the landscape format trend created by video shooting, HD, mobile phones and so on. Though the camera has auto orientation sensing for photos, the display does not change like an Alpha and it’s not really designed well for vertical shots.

The downfacing position is pretty odd. It does not fold out in the usual way. I was able to shoot well enough holding the camera overhead. The screen articulation is, like the 550, a very rugged metal mechanism. It does not feel as vulnerable as many other (more versatile) swivel and tilt rear screens.

The GUI is exactly what GUI means – very much a graphical, not textual, user interface. The six main menu icons resemble mobile phone menus. You get to them by rotating the scroll wheel and pushing its centre button. Shortcuts are marked at the compass points of the wheel for outer rim press-clicks taking you to different options or changing the display mode. The LCD has a glass cover but Sony still offers both hard and adhesive protectors. I took photographs using the ‘Sunny’ brightness setting, not Auto. ‘Sunny’ really boosts the backlight well beyond the auto brightness maximum.

The Brightness/Color Menu includes the options for DRO+ and for HDR shooting. HDR is now three frame bracketing, with manual control up to 6EV span (plus/minus 3). The NEX has a very powerful new BIONZ processor and crunches 3 raw files into an HDR JPEG instantly – while also saving, at the same time, the middle bracketed exposure from your rapidfire 7fps burst as a standard choice. So you get two frames from your triple shutterburst, one normal, one HDR. There are also six-shot Night Scene and Anti Motion Blur modes, which synthesise a final low noise or minimum blur JPEG in-camera; I failed to test these, as the presentations made no real mention of them.

Here you can see the second shutter release, marked MOVIE. Press this and there is no waiting – filming starts immediately, so you either need to be in Continuous AF mode, or have pre-focused using the main shutter release. A second press ends the take. Unlike almost every other HD Video 1080p capable model yet made, the NEX5 will shoot continuously without clip length limits, up to around 29 minutes (filesize limit).

Select Shoot Mode, and an image of a virtual mode dial appears concentric with the control wheel. It turns in perfect sync with the wheel. So, without having a physical dial, Sony has given you one. Text information appears as you perform changes. Some more annoying repetitive cyber-advice can be turned off; other ‘tips’ are not optional. They follow you round for life.

The camera includes many functions aimed at happy young exuberant target-market users. I don’t think it is complete, as the Smile Detection menu has not made adequate allowance for Goths, neo-punks, or grumpy old folk with permanently inverted scowls. A future version for the legacy Alpha-owner generation should include ‘Not Frowning’ as a smile mode!

The Display mode change options include a semi-graphical exposure scale exactly along the lines of current Alpha models.

Alternatively, you can opt for a different set of info more aimed at the advanced user. I found that no matter what display mode I used, the screen became so cluttered I sometimes could not see parts of the subject I was keen to check for alignment, cut off or inclusion in the shot.

This – a very simple display indeed – was what I found most acceptable. It is interesting to note that with the exposure metered live from the CMOS, there was much less need for the plus-minus over-ride function using NEX. I was shooting raw, but even the JPEGs obtained alongside the raw files were pretty much perfectly exposed every time. For difficult subjects the JPEG-only shooter can use a three-shot HDR in-camera process, and this worked very well.

I have a gallery of 48 full size in-camera JPEGs taken during the photo shoot opportunity organised for the press, which involved two hours in sealed dirty-window ferry and bus plus half an hour wasted on a wine tasting (?!) session, for the sake of maybe an hour of pictures. They would have been better just bussing us into Split old city and telling us to meet later. Escorting a gaggle of journos round Hvar town was singularly unproductive!

48 full size in-camera JPEGs with peculiarly deficient EXIF data. Where it says 16mm, the 16mm was used. Everything else is on the 18-55mm. The NEX5 body was used.

The NEX system and the initial 3 and 5 model cameras needs much more writing about it, with many new functions and features. This has just been a small guided tour of the camera for you to see it in detail. We will be posting further reports as time permits, rush-blogging not being something I intend to do when there is so much detailed information to be digested. My quick reports from Croatia and during transit back home have already appeared on the BJP website:

Never feel that your chosen camera makes you the odd one out in a herd of Canon and Nikon users! You are the leader not the follower…

Perhaps you are the only one at your college or your camera club with an Alpha. Well, we reckon that makes you Alpha material, so we have designed two neat logos combining the symbols for Male and Female with the Alpha glyph. It’s an official Photoclubalpha garment not official Sony!

It would have been great to start with a low-cost almost giveaway T-shirt, but the quality of these can be poor especially in black. Yes, even the best black cotton will fade with wear and washing but it is a good quality garment to start with. That’s why it has to be £13.95 including VAT and postage* to cover our costs.

The Polo Shirt is, we think, a real bargain. Various local clubs and societies, as well as sports teams, have had similar polo and rugger shirts made by our supplier with embroidered logos. They look great and wear well at £17.95 each including VAT and postage. Photo above: white male T-shirt, black female T-shirt, black female polo shirt. The polo shirts with the female logo are tailored for women’s fit. T-shirts are unisex.

The T-shirts have the web address of Photoclubalpha written neatly in the classic Minolta typeface across the shoulders on the back. The logo and male or female text line are printed centrally on the front.

The Polo shirts only have the logo motif on the front, to a smaller size, in chest pocket position. There is no text, if anyone asks you what it means, you’ll have to explain it. The Polo shirts feature embroidered logos, the T-shirts are printed.

The T-shirt sizing is fairly generous – for example, size L is a neat fit for female size 20, loose on size 18.

Men’s Polos/all T-Shirts
XS – 34/46″
S – 36/38″
M – 38/40″
L – 40/42″
XL – 42/44″
XXL – 44/46″
3XL – 46/48″
4XL – 48/50″

Women’s Polos
(British Sizes – US sizes are one step smaller, XS=6 for example)
XS – 8
S – 10
M – 12
L – 14
XL – 16
XXL – 18

T-Shirts are unisex not tailored. Polo shirts are supplied in male tailored cut for Alpha Male, female cut for Alpha Female. T-Shirts are Heavyweight 100% Ringspun Cotton (175-180gsm); Polo Shirts are the same material, but a little heavier in weight.

Two more 7D screen protectors later I finally sold the 7D, but only after it had spent three years in the studio where the worst that could happen was a soft landing on the carpet. My Alpha 100 never got a protector but never seemed to get scratches on the LCD. Then the Alpha 700 arrived, and with its lovely hard coated screen I got the same sense of durability you get from glass.

Wrong again! After six months, my Alpha 700 screen was covered in a fine patina of scratches with one slightly visible one. The coating was suffering and I bought a clip-on Sony hard plastic protector. Unlike the 7D model, this one stayed put, but over the next two years of use became a rather scruffy impediment to screen reviewing.

From then on, I decided to put screen protectors on all our Alphas. The Alpha 200 got a thin layer design for mobile phones. It did the job perfectly. The Alpha 350 got a much thicker plastic which felt almost rigid when it was applied, and left we wondering whether it would come off cleanly. The Alpha 900 got a slightly more flexible feeling sheet with a similar not too glossy, slightly uneven surface.

The Alpha 380 was given a Fujifilm LCD protector from the local shop (packs of three, with a cleaning cloth, suitable for all screens around 2.7 to 3 inches). It was still on it in perfect condition when sold. The same pack of foils provided instant cover for the Alpha 550 although its screen and surround really demanded a slightly larger protector.

Then, in February, two things happened. I order some kit from Poland and the on-line store (Foto-Tip) also had GGS toughened optical glass screen protectors. I’ve seen these labelled as Giottos Schott glass protectors and various other makes, generally at around £20 each in the UK, and had my doubts about the idea of fitting adhesive glass to my camera. Also, Alpha fit types were not all that visible in the UK. But Foto-Tip had Alpha fit glass protectors for the A700, A900, A350 and even the A550 – all the Alphas we are currently using.

They were well under £10 each including postage – cheaper than plastic clip-on protectors, a bit more than most peel off films (which also tend to come in packs of two to three, though this is rarely made clear when advertised). So I ordered the entire set. You can see them above.

Before trying anything, I examined the screens and checked their reputation on-line. It seems that they consist of much the same laminated glass and polymer film sandwich which forms the hardened glass for professional Canon LCDs, and that the adhesive is an elastic optically clear gel made by 3M and very similar to that now being used for the intermediate layers in LCD assembly.

In other words, adding this would add a layer – but to the same standards as normal glass-faced LCD, without the superior coating found in a camera like the Canon EOS 7D.

Which camera to treat first came about when the second thing happened – the plastic protector foil on the Alpha 550 must have come loose on a corner, stuck to my jacket and pulled off. I returned from shooting outdoors to find the screen no longer protected, and the camera had been swinging around with zips, straps, other cameras and all kinds of scratch hazards. It was still perfect, fortunately.

Fitting the GGS to the Alpha 550

Using a microfibre cloth, I cleaned the 550 screen very carefully and followed the simple instructions. I left the top plastic protector in place, but they recommend you remove this before fitting as it makes alignment easier. Every GGS protector has a neat black printed edge frame with the camera name. This helps with handling, as if you do get a tiny edge of finger touching the adhesive gel, any resulting mark is hidden behind the black surround.

The Alpha 550 screen surface is slightly recessed. This helped greatly with the exact alignment of the very large cover glass, which goes beyond the image area of the screen and covers all the original plastic face of the panel. There is a shaped edge to match the indent in the rectangle, and a hole in the black frame for the activity light to show.

Alignment was very easy indeed with the rigid screen – far more so than with flexible foils. The adhesion was instant, and perfect, without a single bubble. Unlike a foil, this optically plane sheet doesn’t trap air and even if you did get a dust speck in the sandwich, the gel glue surrounds it without an air pocket.

The thickness of the glass leaves the screen now slightly raised, not slighly sunk, but the edge is beautifully ground and polished so that there is no question of a sharp encounter with your nose or hands. The old foil protector had never reallty been totally clear and was always visible; the GGS protector, though lacking a multilayer coating, improves visibility in daylight compared to a plastic protector.

The perfect flatness of the glass and perfect fit to the camera make a very rewarding finished job. Does it void the warranty? Will it ever be removable? Will the 3M glue layer go yellow with age, or harden and lose contact? Will the screen crack if hit – or will the extra layer stiffen the overall assembly and reduce the risk of damage?

It’s such a permanent-looking and feeling job that I may never find out. GGS say the screen may need to be gently heated, and eased off using a scalpel blade.

The other Alphas

The Alpha 700 had a patinated LCD – six months of unprotected use. Careful cleaning minimised this. The GGS glass screen fits neatly, with its whole thickness adding to the screen which starts flush with the camera. The edge, again, does not feel likely to cut or injure but it becomes the ‘hardest’ edge on the camera. Surprisingly, the adhesive gel seems to remove any the visible blotchiness of the hard coating along with the fine scratches. The single most visible small mark on the screen remains just visible.

While the added glass layer can not improve reflections or viewing conditions, it beats the clip-on plastic shield through which everything was diffused before. The Sony name at the bottom of the screen is now hidden, but can be glimpsed refracted through the clear edge of the protector which sits proud of the surface.

Much the same applies to the Alpha 900, but the screen is slightly recessed (more like the A550) to start with and is changed to having a slightly proud edge once the glass is fitted. It is a bit neater than the A700. It’s recessed just enough to hide the Sony name at the bottom of the screen fully, it can’t be spotted through the side of the glass thickness.

Finally, the Alpha 350 has a thick plastic LCD protector as its outer layer and this stands well proud of the surround. My thought, which I still don’t dismiss entirely, is that this sheet looks as if it could be removed and replaced with the GGS glass. But I was not going to attack my Alpha 350 with a scalpel to find out. If you had a 350 with a cracked cover sheet, it could be worth trying.

With the GGS glass added, the 350 has a pretty ‘high build’ screen – the glass increases the thickness of it by about 50%. It is already pushed into your face compared to the A550, or any other Alpha, with the viewfinder eyepiece too far forward. The extra 0.3mm or whatever it is (I have not measured it) is just a little more ergonomic negativeness. But the edge still feels safe not sharp, the screen assembly appears to be given added rigidity, and I’m happy that this is a good permanent protection for an exposed and vulnerable LCD cover surface.

And…

At the same time, I was fitting my Nikon D5000 with a Delkin Silicon Skin. I just fancied giving my ‘car camera’ a bit of extra protection, and maybe some damping for better video sound. The silicon skin comes with a couple of screen protector foils.

Despite the LCD of this camera being kept face-to-camera (concealed) all the time, and rarely used except for video shooting, my careful cleaning and dusting did not prevent several dust spots and bubbles with the first protector foil. So I removed it, cleaned again, and fitted the second. Still one bubble – and it won’t go away!

That is one very big benefit of these GGS glass protectors. They don’t get bubbles, they are easily fitted with perfect straight alignment, and after a day’s use and handling I have found a quick polish restores a perfect surface. Hopefully, they will resist scratching for years not months, and never need to be prised off their host bodies.

The Alpha System celebrates its Silver Jubilee or 25th Anniversary this month – though left uncelebrated by the inheritors of the Minolta AF legacy, Sony. They have no reason to draw fresh attention to the age of the system, as in four years they have taken it the same sort of distance that Minolta took the world’s first AF system in the late 1980s.

It’s not only Alpha’s 25th birthday. This is also the 25th birthday of modern AF SLR systems – all of them!

This is a multi-page article. See the links at the bottom of the page to Continue Reading after each page.

For Photoclubalpha and the historic Minolta Club of Great Britain, the anniversary does matter. A good many of you out there have been members since the launch of the system, often using the earlier SR and X manual focus systems before that. We still have a 1985 Minolta 7000AF and it’s still working just as it did when new.

25 years before the first Minolta SLRs appeared – a folding Minolta Six of 1935

I don’t mind showing my age to make a comparison. I was 11 in 1963 when I took my first pictures with an SLR camera. My father had bought himself a Pentax S3 – and the camera it replaced was 25 years old, a pre-war Zeiss Ikon Kolibri collapsible 16-on-127 model.

When the Kolibri was made, 127 was the ‘vest pocket’ format of choice. 35mm was on the rise, but 35mm SLRs had not yet arrived. They were as much a thing of the future as digital SLRs were when the Minolta 7000AF was launched.

But within that 25 years, there was hardly a single camera system made with interchangeable lenses that did not become obsolete. Only the ‘frozen assets’ of the cold war kept some systems, like the Exakta bayonet and the Praktina, alive. New brands were launched, from the British Wrayflex and Periflex to the Italian Rectaflex and many German oddities. It was not unusual for an entire system to be come and gone within a few years.

Even in the following quarter-century, the high years of the Japanese 35mm SLR, the succession of lens mount changes was bewildering. Independent lens makers like Tamron and Sigma were forced to make systems using interchangeable mounts not just because the public wanted it. A dozen or more mounts were made for every lens and in the 42mm screw thread fit alone there were endless variants – Praktica LLC (Pentacon Electric), Olympus FTL, Pentax ES and more.

It was more or less a 25-year cycle – the SR system was announced in 1958, and really got underway by 1960. It was to be another quarter century before the AF system arrived. We are now a further 25 years on – can we expect a totally new camera system, once again, in 2010?

Minolta’s SR bayonet mount, introduced in 1958/9, actually remained basically unchanged all the way through to 2005 when the last manual focus model, the X-370S, was available. It survives even now as a mount popular in China where the Seagull range from Shanghai Optical includes Minolta fit models. That mount only ever had one major revision, to add a linkage for open aperture TTL metering. The introduction of programmed exposure and shutter priority was cleverly enabled by using the existing design of lens mechanism and improving its accuracy, while adding a simple reference lug to the ƒ-stop setting ring.

Nikon’s 1959 F-mount proved similarly easy to improve without any basic modification. Both these bayonet mounts celebrated half a century of production in 2008/9 – another landmark, which Nikon was able to celebrate but Minolta of course could not.

In brief, the A450 is an A200 update with an A550 14 megapixel CMOS sensor (the A500 being effectively an A300 update to 12 megapixel CMOS). None of the complaints levelled at the A500/550 or contemporary models are corrected; the same limits apply to EV bracketing, self-timer and mirror up (lacking) functions, control over the range of auto ISO, program shift, functions of controls and buttons, and so on. There may be some surprises present when examined, but the listed specification indicates this camera is exactly what it appears to be.

Camera sets – in every line the first has a fixed rear screen and no quick live view, the second has a quick live view and an articulated screen, the third has a higher pixel count sensor:

A200     A300     A350

A230     A330     A380

A450     A500     A550

The 450 breaks the pattern by using the 550 sensor not the 500 sensor, leaving possible room for a 12 megapixel A400. It’s unlikely we shall see a 14 megapixel A280, but that’s what the model number would be if it was made. In line with speculation, logical models A600, A650, A750 are possible introductions but the Ax30 and Ax80 designations could apply.

It is not an A230-330 style body, but an A5xx-style body, and uses the larger battery – hence the excellent shot count per charge. At the time of posting this information, no further images were available from Sony’s UK press media library.

The logic of this camera may be questioned, but a lot will depend on the viewfinder eyepoint. By choosing a relatively small and safe viewfinder magnification, and removing the articulated screen which forces your eye away from the eyepiece, Sony may come closer to the comfort factor of the Nikon D5000 which despite having an articulated screen allows a closer eyepoint and better visibility of the finder. Until buyers pick up this camera and try it, we can’t be sure. It may just hit the mark perfectly.

The press release follows.

The newest addition to the Sony α family of DSLR cameras teams flawless imaging with generous creative options and is ideal for consumers new to DSLR photography who want the best possible image quality.

Powerful yet easy to use, the DSLR-A450 is a perfect all-rounder when you’re ready to take your passion for great pictures to the next level. Ideal for active shooters, it’s at home in any shooting situation, from relaxed portraits to fast-moving sports action.

Inside the α450 is a high-resolution 14.2 (approx.) effective megapixel Exmor™ CMOS sensor. It’s teamed with the powerful BIONZ processor to deliver highly detailed, ultra-low noise images. Sensitivity extends right up to ISO 12800, allowing you to capture beautifully natural handheld images in low light without flash.

With a generous 95% field of view, the bright optical viewfinder makes framing and composition a pleasure. As an extra refinement, Manual Focus Check Live View previews clear, bright full-resolution images on the 6.7cm (2.7”) Clear Photo LCD screen. With selectable 7x/14x on-screen image enlargement it’s ideal for confirming pin-sharp focus with portraits, still life, macro and architectural scenes.

The powerful BIONZ image processor enables high-speed continuous shooting at up to 5 fps (maximum – approx. figure). In Speed Priority mode (with AF and AE set at start of burst) this increases to an amazing 7 fps (maximum – actual speed depends on shooting conditions and media card). More than enough to catch sports and fast-moving action with ease.

Creative options are enhanced with Auto HDR mode that accommodates bright highlights and dark shadow details in a single frame. Two successive frames shot handheld at different exposure values are merged automatically by the camera. The result is a detail-packed High Dynamic Range image – with no need for a PC image editor and specialist skills. In addition to fully automatic operation, the exposure difference between frames can be manually set up to 3EV, in 0.5EV increments.

Featured right across the DSLR line-up by Sony, SteadyShot INSIDE™ offers up to 4 steps of anti-shake correction with the full range of 30 α lenses and two teleconvertors, as well as compatible A-mount optics by Konica-Minolta.

The α450 also offers the most impressive shooting stamina of any DSLR camera by Sony to date. The high-capacity battery allows up to 1,050 shots between charges* – plenty for a busy weekend’s sightseeing.

Slots for Memory Stick PRO-HG Duo and SD/SDHC memory cards (sold separately) are offered to suit users’ personal shooting preferences.

Connect the α450 to any HD Ready TV for a breathtaking big-screen view of your photos. PhotoTV HD optimises still image reproduction on compatible BRAVIA™ models, while BRAVIA™ Sync allows control of slideshow and other camera playback functions using your TV remote.

Supplied software includes Image Data Converter SR; Image Data Lightbox SR; and PMB (Picture Motion Browser) for easy image management. The α450 is also compatible with the wide range of high-quality DSLR accessories by Sony, including flashes, carry cases, batteries and chargers, GPS and more.

The DSLR-A450 digital SLR camera by Sony is available from the beginning of February 2010.
