Photoclub Alpha

The introduction of a £399 (street price, RRP £449) DSLR with 14.2 megapixels – with or without a useful type of Live View – should have been applauded by reviewers. It’s the single most important point about the camera. No other DSLR approaches this image size and resolution at such a low price.

Now that there are five Sony Alpha DSLR bodies in circulation, with many owners of the original 2006 Alpha 100 considering a replacement, the differences between this ur-Alpha and the 2007-8 generation of Alpha 700, 200, 300 and 350 need examining.

The first SONY World Photography Awards were presented in the late April sunshine of Cannes, to what must have been an exclusive gala dinner audience - at €250 a head, our ‘man on the spot’ Thomas Goseberg decided against the opportunity to take his wife out for a quiet meal…

There’s a lot of controversy right now about whether or not the image structure of the Alpha 700 files at very high ISO - mainly 3200 and 6400 - is as clean as raw processed results from other comparable cameras like the Canon 40D (does not offer ISO 6400), the Olympus E-3 (does not offer ISO 6400) or the Nikon D300. At the heart of this is the way different raw processors handle file conversion, and most specifically, the current performance of Adobe Camera Raw 4.3.1.

The Sony DSLR A200 is now on sale, following the end of Alpha 100 production. Although it is without any doubt the Alpha 100 replacement mentioned by Sony executives in October 2007, when they first revealed that the 100 was no longer being made, it is not an exact equivalent and represents a mixture of upgraded performance and simplified specification. Because it has gone in two directions at the same time, the A200 poses a problem for A100 owners.

The latest full release - no longer Beta, and accepting previous C1 Pro activation keys for unlimited access but otherwise now on 30-day trial - of Capture One v4 now handles Sony Alpha 700 raw files and transforms high ISO rendering in comparison to the industry standard Adobe Camera Raw.

Sony Corporation today announced the development of a 35mm full size (diagonal:43.3mm) 24.81 effective megapixel, ultra-high speed high image quality CMOS image sensor designed to meet the increasing requirement for rapid image capture and advanced picture quality within digital SLR cameras.

In mid 2007, rumours of a 14.8 megapixel Sony sensor came from the usual Far Eastern ‘inside’ sources. As a full-frame Alpha model (the so-called 900) had been previewed at PMA 2007, it was possible this megapixel count related to full frame, or near-full frame. It now looks as if it may have been a leak of development for currently rumoured 14.2 megapixel (active) Alpha 350, which is an APS-C sensor camera.

Sony say that the Alpha 100 has a 230,000 pixel rear screen and the Alpha 700 has 920,000 pixels. What they don’t make entirely clear is how many individual R, G or B pixels are used to create each ‘pixel’ of the image (complete RGB). In fact the 920,000 pixel screen is VGA - 640 x 480 - in display resolution, which is 307,000 pixels not 920,000. What is going on? We took some macro images to show you.

After reading Andrea Nivini’s article in Italian Tutti Fotografi, December 2007, which launches an attack on Adobe’s Camera Raw plug-in and its handling of many camera types - but specifically, the Sony Alpha 700 - I decided to check out whether the December 5th release, ACR 4.3.1, fixed the problems.

The Sony Alpha Unseen Britain Challenge has embarked on its campaign to capture never seen before images of Britain with renowned photographer and climber Mike Robertson. Commissioned by Sony, Mike will tour the country scaling new heights and legendary landmarks to create totally new and exciting photographic images using the new Sony Alpha 700 (α700) Digital SLR camera.

I’m still testing the Alpha 700 and still struggling with aspects of image quality, notably the failure to get much wow factor from straightforward shots in good light. It seems easy enough to get exceptional high ISO images, of the type they are expected to be, but even then many examples seen are marred by a very coarse noise structure.

HARMAN technology Limited, the company behind ILFORD PHOTO and HARMAN PHOTO, has announced the addition of Kentmere Photographic Limited to its business. The move, which comes following a period of extensive negotiations, is being welcomed as a good thing for the brands involved as well as for the wider photographic community.

THE PRESS and trade announcement made below on August 20th 2007 does little to confirm on deny rumours about the forthcoming AA and Flagship DSLRs. Why? You need to study the image, and study the dimension data, and fully understand what they are talking about, before the implications are clear.

THE FIRST QUESTION anyone asks about the Sony GPS-CS1 device is whether it will work with their non-Sony digital camera. The answer is ‘yes’ but you may need to buy some extra software, as it only comes with software to link up to Sony Picture Motion Browser. If you can ensure that you buy the product sold as GPS-CS1KA it should include a copy of this software in full. If you buy the product coded only as GPS-CS1, it may have nothing apart from a patch-updater program you are supposed to use with your existing Sony installation. So make sure you know exactly what you are buying (there appears to be no price difference, and very few retailers are making any distinction between the two bundles). There seems to be no reason to continue offering the kit with the updater only.
