Photoclub Alpha

My review of the Sony Alpha 550 was supposed to appear at the end of November, allowing one week abroad in good weather with plenty of subject-matter, in Tenerife. Sadly that trip had to be cancelled, and the Nikon D3S arrived for review on the day we were meant to have travelled. So, with far too much work to do on the D3S, I’m “going to press” here with my initial thoughts based on a fairly short time using the Alpha 550.

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.

According to Sony UK, the Alpha 5oo and 550 were shipped to UK dealers starting at the beginning of this week (October 19th) – though calls to WarehouseExpress, and to our local Edinburgh Sony ACE dealer, produced no knowledge of the new cameras. WE said that they expected the camera ‘hopefully within the next month’ and Edinburgh Sony Centre Shandwick Place said ‘we will have it in stock on October 29th’.

Paul Genge of Sony UK confirmed that deliveries had in fact been made by October 22nd to selected dealers and that ‘both cameras have been available since the beginning of the week’.

However, a Google search showed no for sale items except Hong Kong based grey market shippers. WarehouseExpress still showed a pre-order status for the Alpha 550 and its kits. We have been trying to obtain one for the past two weeks, as review samples were not available. The initial report in Photoworld magazine has been completed with the help of our Photoclubalpha subscribers round the world who already have the camera, and will appear in the edition printed next week.

UPDATE: Monday October 26th – WarehouseExpress had bodies, 18-55mm and twin lens kits all in stock this morning.

Peter Crouch cuts a striking figure on the football pitch at the best of times and when recently asked to train the UK Sony ‘Twilight Football’ team ahead of their big game on the 22nd September, the outcome was some simply stunning imagery. (Editor’s note – continue reading to see the ‘stunning imagery’… but have somewhere handy to put the hair you tear out)

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.

ACCORDING to specifications revealed on a German site, the new Sony Alpha 500 will have a 12.3 megapixel CMOS sensor capable of providing Live View to the rear 3 inch medium resolution screen – with Manual Focusing at 14X magnification. The in-prism based Quick AF Live View is retained, giving a choice between two entirely different systems of Live View, Sony’s innovative and easy solution scanning the focus screen, and a critically accurate alternative for tripod work. The camera may sell for just €50 more than the Alpha 380 – or break the £500 body only barrier in the UK right from the start.

Tamron’s 18-250mm lens – later adopted by Sony – was so good that it really takes some effort to beat it. Sigma has put that effort in, but the cost is a very much larger and heavier lens. If all you got was some better performance, it might not be all that exciting. But you get potentially superior anti-shake through its built-in OS, and faster focusing with HSM, the Sigma equivalent of SSM.

SONY puts two 10.2 megapixel consumer digicams on the market in September 2009 using the back-illuminated Exmor R sensor. This CMOS sensor architecture takes the ‘sandwich’ which forms the light-sensitive pixel wells, and reverses it so that the side previously used for connections now faces the image-forming light. This change allows more light to be captured, resulting in improved high ISO performance. So far, the Exmor R technology has only been used in video cameras and this is the first appearance of it in still cameras. The cameras can shoot at 10 frames per second.

My Sony Alpha 380 was supposed to arrive before July 13th according to SimplyElectronics.net – via Amazon – claiming UK despatch of 2-10 days delivery after debiting my card on July 6th from a July 3rd order. Well, it didn’t arrive by July 21st, and after some email exchanges I have apparently obtained a refund for the charge they made for an item they did not have (though this was still showing as ‘processing’ in August). Warehouseexpress.com had got the A380 plus 18-55mm kits  by that time, for £10 less, and delivered in 24 hours. Update August 9th: under a month later, the warehouseexpress kit price has fallen by 10% (£50) to £548 inc VAT.

A long-demanded 1.15X eyepiece magnifier – compatible with all APS-C format Sony Alpha DSLRs – is just one of a rollout of new minor accessories for the system. The Magnifying Eyepiece FDA-ME1AM is designed to fit the A700, A380, A330, A230, A350, A300 and A200 and should also be fully compatible with A100, Konica Minolta 7D and 5D.
