Photoclub Alpha

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.

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 specifications of the CMOS 13.1 megapixel, 12.3 effective megapixel sensor used in the Sony Alpha 700 and the Nikon D300 continue to provoke discussion. On the one hand, we have Sony’s own announcement of the ‘commercialisation’ of the IMX21 sensor in August, preceding Nikon’s advance publicity by a few days. On the other hand, we have people who refuse to believe that Nikon, who openly bought Sony CMOS technology to create the D2X, is not entirely responsible for its own sensor.

THE ALPHA 700 cameras tried in Italy by press representatives, including Paul Olsen of Dinside Data in Norway who sent us the raw and JPEG files for the image used here, may or may not have been pre-production samples. Some cameras which were felt to be poor had over 1,000 exposures recorded before the event. Olsen’s camera appears to have been new, recording frame counts in the 40s during his shoot, and may be a final production sample rather than one of the much-used demo bodies.

IT IS very difficult to find a good JPEG from the Alpha 700 pre-production model tests shot in Italy, because too few cameras were available for too short a time - and many of the journalists present were not photographers. But we have found one image you will love.

TEMPORARY website pages on the afternoon (GMT) of September 5th managed to leak the entire specification sheet and several new PR images of the advanced amateur Alpha model, along with its name - the Alpha 700. You wouldn’t pick a wife or husband on the basis of their on-paper specification, so remember, the only way to partner up with a DSLR and be happy is to try it in your hands first.
