The bad news is that anyone using the LR3.2 RC as a temporary free solution for getting full profile correction without investing in Photoshop CS5 will lose their freebie. But Lightroom is eminently affordable, and it can function as a raw conversion front-end for any earlier Photoshop or Elements version. On its own, it is a mere 10MB of program data fatter than Adobe Camera Raw as a plug-in and runs with great efficiency on modestly specified laptops (etc). It’s a lean, keenly priced solution which offers many further benefits as a DAM (Digital Asset Management) library such as keywording, copyright control, metadata editing, version stacking and multiple catalogues.

I am informed that support is included for the 16mm lens on NEX (profile) but I can’t tell whether it is the profile I supplied to Adobe Labs, or a new one, because my profile has remained unchanged on my system – same names, same modification date. And there’s no NEX-3 version which might be expected if they had created new profiles. So it looks as if it could be worth sending profiles into Adobe after creating them.

It’s fantastic news that Adobe has released ACR for the new Alpha 55 16 megapixel sensor before the cameras even hits the street – mine is on order, waiting! Not so great for Nikon users; no D3100 raw conversion in this release. But Canon users get the 60D (despite Adobe missing it out from their front page list). Adobe did this Sony friendly pre-release once before, for the Alpha 100, getting the conversion into place before the camera went on sale.

The bad news is that the Alpha 580 and 560 models are not in the list alongside the fixed mirror pellucid, transflective (anything but Translucent, please…) cameras.

The instruction manual for the Alpha 33 and 55:

http://esupport.sony.com/US/perl/model-documents.pl?mdl=SLT-A33&region_id=1

is already on-line and shows a March 2010 publication date, which means that Sony has had these new cameras in existence since the beginning of the year, certainly well before PMA when mockups were shown. It’s likely that Adobe’s Thomas Knoll has been using one from the first bug-free pre-production model onwards!

Now all we need is the revised lens series with SAM or SSM motors fitted into the 16-80mm CZ, 16-105mm Sony, 18-200mm and 18-250mm Sony; the 11-18mm wideangle replacement, the 75-300mm SAL replacement, and a few other goodies. Hopefully all Zeiss glass gets SSM where possible. That 16-80mm CZ is four years old now as a design. A tweak to the maximum aperture, or the zoom range, would revive interest.

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…

But now, thanks to the wonder of changing language, translucent is also going to have to mean transparent, or semi-transparent. Pellicle, semi-silvered, whatever term you wish to use.

Unfortunately, for this writer the misuse of the word translucent stands as one of the biggest schoolboy howlers ever imposed on the entire world by the ignorance of a corporation. It’s such a glaring error I can hardly bring myself to use the term – others, like Dave Etchells, have happily assimilated the new meaning into their technical lexicon. And as the video above shows, they’ve made it into a trademark, a permanent part of the future of this technology.

Wiki, and pretty well every dictionary ever published, disagree with Sony’s imaginative use of a word from which they have now removed its exact meaning:

Wikipedia: “Transparent materials are clear, while translucent ones cannot be seen through clearly.”

Merriam-Webster:

trans·lu·cent/transˈlo͞osnt/

Adjective: (of a substance) Allowing light, but not detailed images, to pass through; semitransparent.

(the semi bit of semitransparent cited here seems to mean semi-detailed, vaguely delineated – not slightly darker; otherwise the primary definition of the word is diluted).

There has been some heated argument on dPreview forums about this post of mine (my view is shared by many). No-one has made the point that words evolve to have useful exact meanings. Transparent and translucent are words which may once have shared a common poetic meaning in 18th century descriptive writing, but whose meanings were refined with the progress of science and technology. This process in the course of over 200 years resulted in a useful distinction between the meanings of transparent and translucent. Sony’s commercial misuse of the word Translucent is damaging to the English language and to the scientific and technical lexicon; it predisposes future confusion about the meaning of the words.

It is also a fait accompli; there is no turning back, since Sony’s corporate stance is much like that of Mrs Thatcher; no u-turns and never admit to be being wrong. They have also no doubt invested hundreds of thousands of dollars in the consultancy involved, and the registration of the term as a trademark, the creation of branding artwork.

They could have branded the mirror TransLumina® or, more usefully, just called it a transflecting mirror – transmitting-reflecting. That term is already used to describe the sort of mirrors used in ‘Big Brother’ with cameras behind them.

As to whether it’s a true pellicle mirror (a thin stretched film of vacuum coated Mylar or a similar polymer) no-one seems to be clear. It moves out of the way to allow sensor cleaning but could be relatively fragile. It certainly does not need to move to allow 10fps (Alpha 55) or 7fps (Alpha 33) continuous shooting. Sensor dust is often created within the camera by wear and tear on the shutter mechanism, so access for cleaning is essential and the mirror can not be designed to seal the sensor chamber. The Alpha models still have a shutter, that’s the next thing we shall see eliminated. That old rumour of the 15fps silent shooting Alpha DSLR seems to be more than a rumour; we are almost there.

For many users, the critical advantage of all four new Sony models will be HD Video with sensor-based in body image stabilisation. This will enable all kinds of lenses from macro to ultrawide or soft focus, manual adaptations and Minolta AF legacy glass to be used for video with confidence.

Welcome back the circular polariser, unlike mirrorless ILC cameras these new models will not allow the use of linear polarisers without AF efficiency reductions, but exposure should be unaffected as the sensor itself provides the metering with 1200 zones.

This will be one of the tests reviewers need to carry out on the new pellicle mirror Sony Alpha 33 and 55 models – to confront them with not only polarising filters, but conditions in which light is naturally polarised. How will they render sky gradations or reflections off water?

Two further Alpha models are being released, which are essentially updates for the 500/550 – the Alpha 580 which will hit the shops before the winter buying season, adding 16.2 megapixels and a 15-zone AF module, HD 1080p video and (non-video) Contrast Detect AF with all Alpha mount lenses. The 560 will not arrive until some time in 2011, using a 14.2 megapixel sensor.

Versatile features

More of a landmark than a benchmark, the inclusion of 10fps continuous shooting with active phase detect AF and 16.2 megapixel file size in the Alpha 55 is unprecedented and possibly unforeseen by competitors, in this class of sub-$1000 consumer DSLR (let’s continue to use the term, since they are clothed as DSLRs). The dual format card drive supports the 30Mb/s transfer rate of the latest Class 10 SDHC cards and Sony’s fastest MemoryStick Pro Duo generation. The HD video also has a reasonable 17mbps  bitrate.

The new technology has been well documented before the launch, but the fine detail of the new cameras is now clearer. The Alpha 55 is some markets will incorporate GPS geo-tagging for stills and videos (we wait to see whether raw files are tagged, and how accurate this is – the accessory Sony geo-tagging system available to date has only permitted JPEG tagging, and has not been accurate enough to know which street in a town the picture was taken in).

Rumours that the 33 and 55 bodies would be SSM/SAM only, with no internal focus drive, were unfounded as Sony states clearly that both are compatible with ‘the full range’ of over 30 Alpha lenses (indeed, the product shots of the 33 and 55 alone show the 18-200mm SAL DT lens fitted). The 55/33 1080i/60p (1080p in AVCHD camera archive format) video claims ‘smooth, precise’ phase detect auto focus during video shooting, but makes no reference to this being limited to in-lens motor lenses. Therefore we can assume it works with in-body AF drive lenses as well, and you just have to edit the soundtrack.

The new ISO 25,600 mode does not imply a radical sensor change as it is only available using Multi-Shot Noise Reduction, which requires a burst of 6 frames at the 10fps/7fps native maximum speed of the camera, and can not save raw files. The ISO range of the sensors is 100 to 12,800. Is this range quoted as absolute, or after accounting for the semi-silvered mirror light losses? If it’s the range before allowing for the mirror, then the 14.2 megapixel sensor of the Alpha 33 may be more like the Nikon 3100′s sensor than the NEX (ISO 200-12,800) is.

Thom Hogan has shown pixel dimensions and size data which support Nikon’s claim to have an entirely different sensor fab line of their own, compared to the A550/NEX sensor. But how about compared to the A33/560 sensor?

The 55′s new 16.2 megapixel CMOS will probably appear in the forthcoming Alpha 700 successor, which it is believed will form the main Sony exhibit at photokina (Cologne, September 21st-27th). Both models have a new 15-zone AF sensor with three cross sensors, but not f/2.8 sensors – all are designed to operate at f/5.6 virtual aperture. However, there is a hidden clue that the cross sensors may be f/3.5 capable, as the high-speed shooting modes with continuous AF set f/3.5 by default on any lens capable of this (if the lens is, say, only f/5.6 then the largest aperture is always set). Setting f/3.5 implies that this confers an advantage in focus sensitivity over f/5.6, f/4 or any other particular aperture – and that f/3.2, f/2.8 or wider would bring no benefit. That points to some of the sensors having an f/3.5 virtual aperture.

The new cameras are known as SLTs – Single Lens Translucent – instead of SLR. See my intro. Did they have no English speaking staff on their team? I’m sure there is a German word which describes their mirror correctly. I’d rather have the right German word than the wrong English one. Ah well, as the bloke leaning on the pub bar says, durchsprung vor technik…

Confusing aspects – Auto HDR is said to be available in P/A/S/M modes. I guess in M mode it must leave the aperture alone and change just the shutter speed. Regular bracketing is still limited to a disappointing 3 exposures at 0.7 EV intervals, maximum.

But you’ll love the direct D-Range button which gives access to D-Range and HDR options directly, and the direct Finder/Screen button which toggles between using the very high resolution EVF with its ‘virtual 1.1X’ 100% view of the subject – effective visual scale, larger than the Alpha 700 and larger than any previous Alpha digital model except the Alpha 900 and 850. That’s one of the benefits of the EVF, a relatively tiny display is viewed through a high magnification ocular and ends up with a ‘window’ on the world which beats the tiny tunnel vision of optical finders. Technically it is very similar to the last EVF produced by Konica Minolta on the Dimage A200, with the benefit of five years’ further development. It has the same 60Hz refresh rate and visually almost raster-free RGB.

Where the A550 and its earlier stablemates vary slightly around a viewfinder with an effective 0.50X scale (relative to a full frame 100% view using a 50mm lens), the A55 and A33 provide an effective 0.73X and that’s impressive. The ocular is set well back (remember the Konica Minolta A2, and the Sony Cybershot DSC R-1?) because it is a telescope design. This also gives it a very narrow range of possible eye positions, a common feature of EVFs. The eyepoint is close, and you must position your eye precisely.

The rear screen uses the same type of (Schott?) reinforced glass with (3M?) resin gel adhesive as Canon’s 7D – this totally seals to the LCD module itself eliminating air gaps, and improves contrast. It is a technology first seen in the 7D and becoming standard across the industry though the NEX has shown Sony to have the best implementation so far. It is scratch proof, by the way, and it can be cracked by impact like any other screen.

The tilt-swivel action is borrowed directly from the Nikon D5000. In fact, it’s so identical in articulation it even included the amazingly silly front facing mode where the screen is obscured by your tripod, hanging under the camera and preventing it from being placed on a flat surface for self-portraits or videos. But it has the same benefit as the Nikon, the screen can be flipped to face the camera and protected completely while you use the EVF.

Functions familiar from the NEX including Sweep Panorama and Sweep 3D Panorama are built-in and accessed from the main mode dial, which also provides physical settings for all the main modes. Depth of field preview is restored – with the usual button – because is can now actually work. It was always useless in real terms on optical viewfinder cameras, as the focusing screen never represented wide apertures correctly.

Now, with an EVF, for the first time ever an eye-level Alpha gives absolutely perfect and precise previewing of depth of field and bokeh effects whatever aperture you are working at – even at f/1.4, which was never possible and still isn’t with the A850 or A900 for that matter (which is why their Preview mode is useful).

You can also preview the exact image appearance. By pressing the AE lock button, the auto gain of the EVF or rear screen are turned off and replaced by an exposure-compensated view. So if you dial in -1 EV (using the adjacent dedicated button), and change the WB, and use a different picture style with more saturation and contrast just pressing AE-Lock will immediately preview your image with these adjustments applied. And you can enlarge in the usual two steps to check auto or manual focus.

The finder and screen also have a Nikon-style two axis spirit level (flight simulator horizon) display to help you get your horizontals straight and your verticals parallel. It can be activated on either, and does not have to appear on both simultaneously.

For movie makers, the binaural stereo microphones are a great move. Even on the NEX, the two small top aperture mics give excellent stereo. The 33/55 mics are placed either side of the ‘prism’ housing, rather like the ears on your head. This will give the stereo image created by these cameras a really natural quality. Natural, that is, to a pygmy marmoset monkey… but still, I will wager, the best stereo image of any DSLR/HybriD. And Sony provide a stereo 3.5mm mic jack socket, though without any manual control of gain levels.

I’m sure we will have to buy the A780 to get that. Click the picture above for a big version. Who says Sony does not have a range to match Nikon or Canon, whether or lenses or of cameras? From the left, the cameras show the current range before we even see the magnesium-bodied Alpha 700 replacement arrive. A900, A850, A580, A560, A55, A33, A390, A290.

Read Sony Press releases and full technical data:
Alpha 33 and 55 Press Release
Alpha 560 and 580 Press Release

Following the release of Adobe Camera Raw 6.1 and 6.2, the new ’2010 Process’ has replaced the ’2003 Process’ in conversions (you can select either option). The 2010 Process used with manual adjustment of the Noise Reduction controls can produce really exceptional ISO 6400 results.

This changes any previous conclusions about the usefulness of Alpha 550 high ISO settings, and indeed brings them into line with the results we have seen from NEX – which of course defaults to the 2010 process, and can not be processed using earlier Adobe Camera Raw versions.

Here is the old process, top, seen at a reduced scale of a 100% view at ISO 6400:

Click the Process 2003 image above to open the original 100% size screen shot.

Below is the new 2010 process, which is more than just a minor tweak – it’s an entirely different way of getting the data out of the raw file.

Click this image to see the Adobe Process 2010 result full size. All the settings were identical for these two conversions. The improvement is on such a level that ANY test reports on the Alpha 550 produced in 2009 using CS4 and Adobe Camera Raw 5.x are invalid.

The NR can be moderated to produce more detail on the 2010 process midtones at the expense of more visible grain (but it’s nothing like the 2003 pattern – it remains mainly a fine luminance pattern). I have used a setting which produced a clear comparison. Entirely different NR settings are actually better, with the two processes, but no matter how you adjust the ’2003′ version it never looks anything like as fine as the 2010 one.

Should dPreview and others update their RAW sample images because the old process was so badly matched to the .ARW format? Nothing like the same difference is made for example to Nikon raw files, 2010 is better, but 2003 didn’t mess up the higher ISOs in the way it always did for Minolta/Sony raws.

Please note that if you don’t want to get CS5, you can still get the benefit of this new conversion with Adobe Photoshop Elements 8.

Right click to download this 56Kb file which should be placed in the Lens Profiles/1.0/Sony folder of the directory on your computer which holds Adobe Lens Profiles.

This profile has been created at full aperture and f/8-f/11 depending on focal length, at 16mm, 24mm, 35mm, 50mm and 80mm focal lengths and involved 90 raw captures.

It is possible in ACR/Lightroom to use profiles which are not created on your own camera type. This profile can be applied to any APS-C Sony or Minolta camera using the 16-80mm lens; because the A550 is currently the highest resolution body, the CA data gathered is more accurate than would be possible using a lower resolution body but may need a saved adjustment in defaults. Individual lenses differ slightly and may also need adjustments.

I have checked the operation of the profile on files from A100, A700, A200, A380, A350 and A550 and it’s very effective in removing CA. Illumination is much improved at 80mm (notably). You may prefer to turn the geometric correction down to zero (off) when the angle of view matters more than perfect straight lines – and also, where people are in the shot near the edges at 16mm. The distortion of the lens is optimised to lessen ‘stretched faces’ at the ends and corners of the shot, applying the profile removes this slight barrel distortion and does not improve groups. It’s most useful for horizons, rooms, seascapes, and subjects where a good straight rendering is critical.

It has been suggest I should add a donation button for these profiles. By all means see our subscription page, there’s a downloadable PDF of the latest Photoworld magazine for $3. I could easily have zipped profiles and sold them in the same manner, but that is not why photoclubalpha is here; Adobe provide the software to do this free (OK, I know what the rest of their stuff cost me…) and profiles should be made public domain by creators.

Uncorrected 16mm shot

Using Adobe Camera Raw 6.2 RC with the profile active at default settings

JPEG profile added (17/08/10)

I have now added a JPEG profile from the same set of images as the raw – this is lucky, I didn’t think people would need a JPEG profile but happened to have the camera set to RAW+JPEG when the test shots were made, and this has been requested for those using HDR or other JPEG-only modes.

Using the profiles

A full Adobe Profile is undertaken at several focus distances, apertures and zoom settings (or for prime lenses, just at a range of distances and apertures). The largest chart I can print is A2+ using the Epson 3800, and with a 24mm equivalent lens, this means having the camera surprisingly close to the target. The profile is therefore only 100% correct for subjects at 115cm from the camera, which corresponds to the 4X minimum focus distance suggested by Adobe.

I have found from using the 16mm that its optimum aperture for central sharpness is probably f/5.6, and that chromatic aberration and vignetting do not improve at stops smaller than f/8. There is a slight improvement in detail sharpness in the extreme corners at f/11 and f/16, but this is due to extra depth of field helping to cover a curved focus field. I therefore made test sets at f/2.8 and f/8 for this profile.

The geometric distortion is most visible with closer subjects such as the subject above (The Slave Girl, a bronze c. 1870 by John Bell, at Cragside House in Northumberland). This is a hand-held exposure of 1/4 at f/8, and is perfectly sharp despite the lack of stabilisation; every word of the interpretation can be read at 100%. I have found most shots are perfectly sharp with the 16mm given reasonable care, as you would take with a Leica, to breathe correctly and make a shake-free exposure. This is not the case with SLRs where the mirror action nearly always causes shake.

For more distant subjects, the 100% default setting of the ACR/LR Lens Correction panel can be reduced and where there are few straight lens removed entirely to secure the maximum field of view. Similarly, the vignetting correction can be reduced or removed entirely as the natural darkening towards the corners with this lens is attractive.

Although this profile is named to match perfectly the naming convention used by Adobe for the 18-55mm, I find that ACR 6.2 can not be relied on to use it for Auto as a default (if you work with more than one lens, Adobe Lens Correction soon proves unpredictable in this anyway). If you select Auto, then select Sony, the lens profile will be selected but the Auto button changes to Custom. If you then save new Lens Correction Defaults, or Camera Raw Defaults, ACR will attempt to force this profile on the 18-55mm and the reverse will also happen. So it’s necessary to check which profile is selected. Using ‘Previous Conversion’ for shots taken on the same lens is a quick way to get there.

The additional Manual Controls can be used on top of the profile (the second tab of the interface). The most useful are the geometric distortion (camera angle) corrections. The Chromatic Aberration/Colour Fringe controls can be fine tuned as the correction for CA while very effective relates only to the tested focus distance. CA may change with focus but my particular lens doesn’t seem to suffer from this. All that is necessary is to enable Defringe All edges as a default, and this will remove any hint of colour remaining. As a tip, setting Colour Noise Reduction to a high value can help remove CA and purple fringes in many shots processed through ACR/LR. The colour NR detects 1-2 pixel fringes just the same way it detects individual pixels, and neutralises much as it does noise.

- David Kilpatrick

But they let Sony down in a big way by only including the 18-55mm OSS lens for NEX, omitting the 16mm which must be very simple to profile (after all folks, there are only TWO officially available lenses for NEX right now – you found time to profile no fewer than 15 lenses for the Pentax AF645, for the benefit of all two dozen worldwide users of this outstandingly popular digital option…)

It also proved very competent with the Sigma 70-300mm f/4-5.6 OS lens, the adaptor providing power for the OS which is fully functional, and also for auto exposure, leaving only manual magnified focusing to tackle. The OS Sigma has an internal motor for focusing on Alpha, not screw drive though it sounds and feels like it. It’s not HSM and almost certainly won’t be friends with any AF enabling update of the NEX/Lens Mount Adaptor firmware.

One lens I have obtained a coupled of sample of to experiment with, even if it means dismantling one. That is the Minolta Vectis 80-240mm f/4.5-5.6 APO, a miniature version of the 100-300mm APO made for 35mm, in the APS Vectis mount. This mount is all-electronic like the Vectis, but probably very different in the voltages required and the command protocol. But who knows? Maybe an AE adaptor with power for manual focus might be possible.

Using a Zenith 39mm (Leica type SLR) thread T-mount the Vectis 80-240mm nearly focused OK attached to the Leica adaptor of the NEX, but the bayonet was only just able to fit in a doctored T-mount and the combination with the NEX Leica screw adaptor was clearly a little too thick.

Using a Leica thread lens reversing ring (don’t ask, from my box of miscellaneous old rings and things – 49mm filter to Leica screw!) and duct tape, I was able to fit one of my two 80-240mm APO guinea-pigs to the mount within 1mm or so of correct register (38mm). It’s only taped, but solid enough. I do not want to cement the bits together at this stage.

Effectively it’s got a Leica screw mount taped as close to the Vectis lens mount as anything will allow. There is plenty of room to make a proper Vectis adaptor, with or without contact arrays at both ends and a chip to convert the signals. Without that, the lens is stuck forever at full aperture. If power could be supplied to the correct pins to enable the focus-by-wire action, that would complete the job with this Vectis lens – but other Vectis lenses don’t even have a manual electronic focusing option. As it is, wrenching the front tube round focuses the lens. Just like it did when you were fitting or removing the lens hood, a frustrating rotating front unit.

As it stands, the 80-240mm Vectis APO f/4.5-5.6 is a really neat size of lens for the NEX and Sony could do far worse than remake this in an OS version for NEX. At full aperture, performance up to 200mm is very good but a familiar softness (like the 100-300mm APO D at 300mm etc) creeps in at 240mm. For 1996, the lens is pretty amazing.

And at 240mm close focus again:

This lens has some really good qualities, considering it is not even mounted correctly and is definitely not correctly set up for register, which alters the way the zoom/focus correction functions. It could no doubt be made to look better by picking a flat target and a medium distance, rather than homing in on garden close-ups with too much depth for the wide-open setting.

But the bokeh effects are not too bad, the point of focus is well defined, and the lens has few vices considering the imprecision of its mounting!

Sony is expanding its line-up of over 30 A-mount lenses with new models that will appeal to seasoned photographers and those new to DSLR cameras alike – a 35mm f/1.8 DT (APS-C) SAM, an 85mm f/2.8 full frame SAM, and the long-awaited 24mm f/2 Carl Zeiss Distagon T* 24mm f/2 for full frame with SSM ultrasonic focusing. In the interests of getting this report on line, it’s mainly Sony words, with a few added comments and edits.
The Distagon T* 24mm F2 ZA SSM (SAL24F20Z) features Carl Zeiss Distagon design and rounds out the existing Planar (SAL85F14Z) and Sonnar (SAL135F18Z) models also developed in conjunction with Carl Zeiss. It is intended to appeal to experienced photographers looking for a large-aperture wide-angle lens of real distinction.

The DT 35mm F1.8 SAM (SAL35F18) adds the important 35mm focal length to what Sony now calls the ‘Easy Choice’ series. ‘Easy Choice’ is intended to provide great value, compact and lightweight lenses that are attractive to entry-level and advanced photographers alike. Each lens in the series is selected for a specific purpose, for example portraiture or macro. – Sony definition.

The 85mm F2.8 SAM (SAL85F28) is another ‘Easy Choice’ lens, this time offering the 85mm focal length considered the standard for portraiture because of the natural perspective it provides. True to type it is extremely compact and light, weighing just 175g.

The Distagon T* 24mm F2 SSM (SAL24F20Z)

The Distagon T* 24mm F2 SSM (SAL24F20Z) functions as a wide-angle 24mm lens on full-frame cameras with 35mm sensors, or as a 36mm equivalent lens ideal for general use on cameras with APS-C sensors. Jointly developed with Carl Zeiss, it features the highly-regarded Carl Zeiss Distagon retrofocus lens configuration.

This lens is distinguished by its fast response focus and extremely quiet, very smooth operation thanks to its built-in SSM (Super Sonic wave Motor). It offers a focusing range from 0.19m (0.29X scale) to infinity, and a nine-blade circular aperture along with a large f/2 maximum aperture contributes to smooth, natural bokeh effects. The design uses 9 elements in 7 groups, with two aspherical and two ED glass (so it’s a modern Distagon derivative, nothing like a classic Distagon).

The all-metal lens barrel has been ‘finished to a very high standard resulting in a visibly high-quality appearance’. It takes 72mm filters, weighs 555g, is 78 x 76mm in overall size, and comes with a lenshood, case, front and rear caps.

The DT 35mm F1.8 SAM (SAL35F18)

The DT 35mm F1.8 SAM (SAL35F18) weighs just 170g. It can be added to a lens kit system and carried without noticeably increasing the weight of the bag.

With an approximately 50mm (35mm equivalent) focal length on an APS-C sensor, this lens is ideal for snapshots and portraits under a wide range of shooting conditions. The high-speed f/1.8 maximum aperture is particularly advantageous for hand held shooting in low light.

At just 0.23 metres (0.25X scale, so actually less good for close-ups than the 24mm, oddly), the DT 35mm F1.8 SAM (SAL35F18) has ‘the shortest minimum focus in its class, making it an excellent choice for dramatic close-ups too’. The internal Smooth Autofocus Motor (SAM) drives the focusing group directly and may, if all goes well, turn out to be compatible in future with continuous AF during video shooting.

It uses 6 elements in 5 groups, takes 55mm filters, is 70mm x 52mm in size, and comes with hood and caps.

The 85mm F2.8 SAM (SAL85F28)

This is the first full-frame lens in the ‘Easy Choice’ range, so its launch represents an important development of the line-up as a whole. The 85mm focal length is a standard for portraiture because of the natural perspective that it provides. On an APS-C sensor camera the 85mm F2.8 SAM (SAL85F28) functions as a 127.5mm (35mm equivalent) telephoto lens – and features a Sonnar-type optical design that is considered ideal for mid-range telephoto lenses.

The lens is sharp center to corner, and features smooth defocusing thanks to its f/2.8 maximum aperture and circular aperture design. At 0.6 metres (0.20X, so not as good for close-ups as either the 24mm or 35mm!), the minimum focusing distance is the shortest in its class, and SAM motor technology ensures smooth autofocus operation (see above, but bear in mind that SAM is basically a cheaper alternative to ring-type SSM).

‘The quality optical and mechanical features of the lens mean it is suitable for serious photography and should more than satisfy intermediate to advanced users’, add Sony.

It has 5 elements in 4 groups, takes 55mm filters, is 70 x 52mm in size and weighs only 175g; it comes with hood and caps. Maybe the classic MD 85mm f/2 would have been nicer to see in SAM form, but f/2.8 is plenty these days.

The prototype or dummy shown to the press in Croatia and other locations just two month ago turns out to have been little more than a rubber duck – a decoy to distract while the real thing was clearly already in production and looks very different. The real thing has an eye-level 1 megapixel-plus electronic viewfinder as well as a foldout screen, and the world’s most retro-tech microphone design.

Here is the press announcement from earlier this morning (GMT, I don’t man the computer at 6.17am but Sony’s Press Centre was wide awake and running). The guy in the Sony press pix obviously found 6.17am a bit rough, he looks worse for a long night out… he’s not even got himself in focus properly, let alone found out where he left his comb and razor…

“Camcorder Redefined” Sony unveils world’s first consumer interchangeable lens HD camcorder Handycam® NEX-VG10E captures cinematic Full HD movie and stereo sound with great depth

• 14.2 effective megapixel ExmorTM  APS HD CMOS sensor (19.5 times larger than conventional camcorder) for stunning HD movies with beautiful background defocus
• Accepts E-mount interchangeable lenses plus A-mount α DSLR lenses (via optional adaptor)
• High quality audio with Quad Capsule Spatial Array Stereo Microphone and external mic input
• 7.5cm (3 inch-type) Xtra Fine LCD and electronic viewfinder

Building on 25 years of continuous Handycam® innovation, Sony introduces the NEX-VG10E – the world’s first consumer HD camcorder with interchangeable lenses. It’s also the first Handycam® featuring an extra-large Exmor APS HD CMOS sensor that allows the creation of exquisitely cinematic background defocus effects.

Targeting video enthusiasts and photographers, the NEX-VG10E opens up unprecedented artistic possibilities not achievable with conventional consumer video cameras.

Compatible with a choice of high quality E-mount lenses, it’s the first consumer camcorder that offers the same breadth of creative expression enjoyed by DSLR photographers. Alongside the three currently available E-mount lenses, users of the NEX-VG10E can experience a wide variety of  A-mount DSLR optics by using the optional LA-EA1 mount adaptor. Picking from a choice of award-winning Sony G lenses, fixed-focal length Carl Zeiss portrait lenses and other models from macro to super-telephoto, videographers will have unprecedented freedom to explore an exciting world in movie creation.

At the heart of the NEX-VG10E is a 14.2 effective megapixel Exmor APS HD CMOS sensor that’s teamed with Sony’s powerful BIONZTM processor to capture very high resolution video and still images. Approximately 19.5 times bigger than the standard sensor found in other consumer camcorders, the APS-C sized imager also enables an extremely shallow depth of field. This allows videographers to achieve ‘cinematic’ results with beautiful background defocus (bokeh). In addition, the ability to capture DSLR-quality still images gives videographers extra shooting flexibility on assignment with less to carry.

Full HD 1920×1080 video images are captured in AVCHDTM format at up to the maximum 24 Mbps bit rate for superlative detail and clarity. Unlike many digital still cameras including DSLR that support HD video, there’s virtually no restriction on continuous shooting time. Just slip in your choice of either Memory Stick PRO DuoTM or SD media cards and capture Full HD video and JPEG still images for easy transfer into your existing PC storage and editing environment.

The NEX-VG10E comes supplied as standard with an image-stabilised E18-200mm F3.5-6.3 OSS lens that offers a powerful 11x optical zoom range. Because of its optimized design for video shooting, this high-quality E-mount lens offers smooth, ultra low noise autofocus and iris control. In-built Optical SteadyShot image stabilisation assures clearer video images when you’re shooting handheld. At wide angle settings, Active Mode enhances anti-shake performance even further, steadying jittery images even while walking. The lens also features a circular aperture for the creation of beautiful bokeh effects whether you’re shooting video or stills.

Reflecting the demands of serious videographers, sound quality matches the phenomenal imaging performance of the NEX-VG10E. The Quad Capsule Spatial Array Stereo Microphone uses advanced processing algorithms to combine signals from four separate omnidirectional microphone capsules. The result is exceptionally clear stereo audio with a highly directional response: this allows videographers to capture more sound from the subject they’re shooting, and less of distracting sounds around them. There’s also a jack for adding an optional external stereo mic, plus a headphone jack for audio monitoring.

With a photo-realistic 921k dot resolution, the 7.5cm/3 inch-type Xtra Fine LCD features TruBlackTM technology for an exceptionally detailed, high contrast view of images and menu settings. The LCD is supplemented by a high-resolution (1152k dot) electronic viewfinder that assists easy framing and monitoring. The viewfinder helps operator capture clear images in bright daylight and its angle can be easily adjusted for comfortable operation.

Despite its groundbreaking creative possibilities, the NEX-VG10E is compact, beautifully balanced and easy to handle, even for novice videographers. An intuitive jog dial and hotkeys make it easy to navigate camera menus and adjust shooting parameters. Videographers can also enjoy precise manual control over Iris, Shutter Speed, Gain and White Balance for professional results.

A range of official accessories includes the ECM-CG50 Shotgun Microphone that attaches to the camcorder’s accessory shoe. There’s also a choice of rechargeable battery options, including the NP-FV100 that provides power for up to 330 minutes continuous HD shooting. A dedicated soft carrying case LCS-VCD is also available as an option.

Offered to customers as a free download, Vegas Movie Studio HD Platinum 10 video editing software includes everything you need to produce spectacular HD movies. Powerful tools for video compositing, colour correction and sound mixing make it easy to achieve cinema-quality results in your own home studio. You can also upload movies to web, burn them to Blu-ray Disc™ or author DVDs with custom menus and graphics.
