Photoclub Alpha

SONY has shown itself to be lagging behind the competition as we reach the third bend on the second lap of the development of HD-video capable DSLRs. At PMA 2010, nothing ‘real’ was shown and the closest they came to further launches in the Alpha range was an advanced pre-production prototype of a 24mm f/2 Carl Zeiss T* ZA SSM.

But Sony may prove yet to be the tortoise – or perhaps to be Brer Rabbit. They could make the finishing line, the goal of a truly useful video DSLR, before Nikon/Canon/Pentax/OlySamPanny get there.

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.

Tokyo, Japan, November 10, 2009 — Ricoh Co., Ltd. (president and CEO: Shiro Kondo) today announced the development and release of the GXR interchangeable unit camera system featuring the world’s smallest and lightest* digital camera with the ability to change lenses.

The new GXR is an interchangeable unit camera system in which lenses are changed by using a slide-in mount system to attach camera units to the body. The lens, image sensor, and image processing engine are integrated into the camera units so the body itself does not contain an image sensor.

With world-leading small size and low weight* enabling easy carrying, the GXR interchangeable unit camera system features a highly rigid magnesium alloy body and multiple camera units that can be changed to best fit the scene to be photographed. You can enjoy easy lens changes as well as amazing image quality and shooting flexibility. Concealing infinite possibilities in its small body, the GXR is a revolutionary camera system that pioneers a new realm of photography.

Distinctive characteristics:
1.    Lens, image sensor, and image processing engine comprise an integrated unit which can be changed to match the scene being photographed.
2.    World’s smallest and lightest* digital camera with interchangeable lenses
3.    System potential expanded through use of interchangeable units

Comment from David Kilpatrick:

Though the Ricoh system as revealed through this press release appears to show only a GR-size body with a zoom lens module suitable for a 2/3rds or slightly smaller imaging sensor, Ricoh has said that sensors right up to the size of APS-C will be built in to further lens modules. The ultra-wide angle version would have an APS-C sensor making similar to the Sigma DP-1. For similar reasons, high ISO and fast lens may be combined with a different size of sensor.

This is not the first time a digital camera has been designed with lens-sensor modules that could be changed. The Minolta Dimage EX 1500 accepted either a standard zoom module, or a wide-angle module. These included viewfinders (missing from the Ricoh concept, which relies entirely on the rear screen or electronic viewfinders) and had the unique ability to be removed from the camera on a 1.5m long Cable EX. This allowed users to position the wide-angle module inside scale models, doll’s houses and similar subjects to obtain realistic human-scale perspectives. It was only a 1.5 megapixel camera, and Minolta abandoned the concept before they had a chance to develop it further, whatever dPreview said ten years ago:

The technology behind the Ricoh is not all that different from the way consumer digital cameras are constructed anyway. Lenses are already sold sealed to CCD/CMOS sensors, as a single unit. That is how the OEM sources of the lens-sensor modules market them. At photokina, you can see (every two years) a new crop of such modules with both the technical resolution specs of the optical unit and the megapixel count of the sensor, identifiable to this non-Chinese/Japanese reader in the middle of a description which is usually inb Chinese. In 2006, I tracked such a module from its maker to the first camera I could find which used it – a compact branded as Vivitar. The customisation consisted of building any body the maker chose to design, and putting a ring on the lens front labelling it is a high resolution Vivitar lens; actually, it was just a generic lens-sensor assembly from China.

Ricoh has also pioneered unusual digital designs in the past, including rotatable or detachable lens modules and one of the first viewfinder-less designs, where the viewing screen was intended to be used at waist-level rather than today’s habit of waving the camera in front of your face.

This differs from anything previously done in the power of the CPU unit in each lens module, and the control unit with display and card module in the host body. It should allow any reasonable pixel count and sensor size to be built in to future optical modules. If the accessories do eventually include dedicated APS-C lens-sensor sealed modules, ‘dust on sensor’ will be one clear benefit (or the lack of it will). A supertelephoto module is also planned which will use a sensor smaller than APS-C.

Sony Corporation today announced the development of a highly efficient wireless power transfer system that eliminates the use of power cables from electronic products such as television sets. Using this system, up to 60 Watts of electrical energy can be transferred over a distance of 50cm (at an efficiency of approximately 80%, approximately 60% including rectifier).

Sony Corporation today announced the development of a single lens 3D camera technology capable of recording natural and smooth 3D images of even fast-moving subject matter such as sports, at 240fps (frames per second).  This technology combines a newly developed optical system for single lens 3D camera which captures the left and right images simultaneously, together with existing high frame rate (HFR) recording technology to realize 240fps 3D filming.  Sony will demonstrate a prototype model incorporating this technology at “CEATEC JAPAN 2009”, to be held at Makuhari Messe convention center in Chiba city, Japan, from October 6th.

I don’t have an Alpha 500 or 550 here yet, even though Photoclubalpha has been second in the Google search results for ‘Sony Alpha 550′ for some time and remains so as I write (the New York Times is first). That’s not bad for a Wordpress blog website which does NOT employ the services of the dozen or so ’search engine optimisation’ experts who contact us each week! Hopefully we’ll have a review camera very soon, preferably the 550.

In the meantime, a few samples have been posted on various sites which show the raw conversion engine of the camera/s (not necessarily the JPEG compression stage, as always seems to be assumed) has been radically revised. Sony call this ‘enhanced BIONZ’ and I think there’s a clue to how it has been enhanced in the relationship of Sony Europe and DxO Labs, the French company which specialises in in-camera process analysis and development.

Sony’s September launch for 2009 looks set to include three new models – the Alpha 500, 550 and 850. The model numbers are confirmed by the usual backdoor leak, appearing in the registration database for SonyStyle USA in this case (Canada has been a past culprit, updating databases associated with their site before the product is officially released). However, only a few people know what these cameras will be, and they are limited by non-disclosure contracts.

The new Alpha 230, 330 and 380 models are radical ergonomic redesigns of the existing 200, 300 and 350 series. There is a 15% reduction in size (volumetric) and weight, an update to the styling, and a completely revised user interface with graphic representation of setting adjustments – with a built-in ‘handbook’ to accompany the modes and options. They also have mini-HDMI image output, compatible with Bravia TVs and with interactive software inside the camera to allow the Bravia’s own remote control to change, orient and zoom into images (Bravia Sync). Twin card storage is MS ProHG Duo/SD and only one card is usable at a time, with a hardware switch to change slots. A smaller battery type (shared with the HX1 Cyber Shot) is used. A new self-timer drive mode grabs a quick burst of 3 or 5 frames, cutting the chances of spoiled portraits and groups shots when someone blinks at the wrong moment.

The new flashgun HVL-F20AM operates as a wireless flash controller for the full-frame α900. “While Sony’s flagship DSLR does not have its own integrated flash, the HVL-F20AM can be used as an inexpensive trigger for wireless remote flash heads” according to Sony UK.

Tamron Co., Ltd (Mr. Morio Ono, President), a comprehensive manufacturer of optical products with its head office in Saitama City, has announced the development of the SP AF60mm F/2.0 Di II LD (IF) MACRO 1:1 (Model G005), a life-size macro lens designed exclusively for digital SLR cameras with APS-C size image sensors* that offers a fast maximum aperture of F/2.0. (Text here is directly from their press announcement).

Sony’s new back-illuminated CMOS sensor design makes its first appearance – along with technology borrowed from the Alpha system – in a new HD Handycam video model, the HDR-XR520VE/500VE. Hopefully presaging future DSLR developments, the range also includes models with built-in GPS tracking to record the location of shots as you film.

Part 3 of the conference presentations, transcribed from a recording by Shirley Kilpatrick. This section deals with the revolutionary new adjustable focusing screen and viewfinder which enables error-free 100 per cent viewing, and the reasons Sony chose to make a 24.6 megapixel full frame sensor. To start reading with the first Part, go to Part 1.

It is mainly about HDTV Motionflow, LED technology, Reader, OLED (Organic LED) screens, Handycam, the electronic Picture Frame, something called Sountina which appears to radiate sound from a column speaker – etc. It features Fujio Nishida, President of Sony Europe; Chairman and CEO Sir Howard Stringer making jokes which fell on a rather mirthless set of ears;

“We continue to grow our enormous digital imaging business where we maintain leading market share”, said Stringer, before lauding the success of Blu-Ray (something which was by no means sure until recently).

He promised network connectivity in 90% of devices in 2010 – which means, perhaps, that DSLRs will have built-in WiFi, just to keep up the count towards a target figure. But he also refers to “electronic” devices in this context, and the Alpha division appears to be a separate category.

He said that Sony has committed to doubling its revenue from countries like China, Russia, Brazil and the Eastern European zone. “The global economic downturn is beginning to have an effect on Western Europe”, he told the journalists, but the east was showing a 25% growth. Eastern Europe and Russia show a 60% sales increase for Sony. Poland showed a 65% sales increase in the first four months of 2008. In Turkey, Sony has seen 43 months of consecutive growth, increasing by 500% in five years.

Nishida said that new products would be launched in Europe on the same date as in Japan. These include the OLED TV XEL-1 which is only 3mm deep. The Bravia EX-1 HDTV will receive its HD content via a wireless link from a media box sited up to 30 metres away. It mounts on the wall like a picture, without wires except power supply.

He said that the 50Hz frame rate of TVs was now old-fashioned and too slow for fast-moving sports. Motionflow introduced 100Hz in March 2007. The new Bravia 200Hz Z-4500 has four times the frame rate of standard HDTV, using algorithms to interpolate between the frames of the original. It will be on sale by Christmas.

New LED TVs would use side-injected illumination instead of a lighting panel placed behind the picture elements. The Bravia ZX-1, only 9.9mm thick, is the world’s slimmest TV and uses this new illumination method. It will also go on sale in Europe in December.

After discussing Blu-Ray, Nishida introduced the Sony T-500 with 10.1 megapixel still camera shooting 720p HDTV video clips, which goes on sale from this month. He then moved on to Walkman S-series players including photo storage, and mood sensing – it will pick the right music to play according to your activity level.

The Sony Reader was explained in the conference by Nishida – it is an electronic book reading device – and its first launch will be in the UK this week, followed by rollout in other countries. Nishida-san concluded with discussion of built-in wireless networking and control connectivity, including reference to Cybershot cameras but not to the Alpha range.

Simon McDowell, of Sony Entertainment Europe, spoke mainly about Blu-Ray and home entertainment. The most spooky thing is a new Blu-Ray based feature, BDLive, which lets you upload a snapshot of yourself into a movie and appear in the film…

Fujio Nishida concluded the press conference by announcing football sponsorship of the EUFA Champions League – a new signing to continue for a further 3 years up to 2012. “We have some exciting technology developments planned for football in the coming months”, he said.
