Photoclub Alpha

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.

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.

It’s the same on every web forum - if you post a digital picture which would be acceptable to a photo library or professional buyer, half a dozen grumpy one-liners will come out saying ‘That don’t look sharp to me’ or ‘there must be something wrong with your XXX’ (fill in D300, A700, E-3, D3, 40D as required). Then someone posts a hugely messed up image and people say ‘Wow! What sharpness!’…

Adobe has posted updates to Photoshop, Lightroom, and the Photoshop Camera Raw plug-in, both available immediately for download on Adobe.com. The updates provide raw file support for 14 additional camera models and camera backs within Lightroom and Camera Raw, including the Sony Alpha 700. Links here.

THE question is being asked, will the Alpha 700 match the rich colour rendering of the Konica Minolta 7D and 5D? These cameras had identical colour profiles, and were in turn very similar to the Dimage A1 and A2. The Sony Alpha 100 proved very different. Here’s my best attempt to explain why.

THE appearance of press-release resolution (14Mb) images of the new Alpha - un-named but thought to be the Alpha 200 or 300 because of the product code earlier assigned to shots of prototypes at PMA - combines with reports on various forums from European Sony executives visiting Japan to suggest that the launch announcement for the new model and a range of full-frame lenses is imminent.

Shortly before the June 6th 2006 worldwide launch of the Sony Alpha digital SLR system the European press learned that major title editors would meet in Marrakesh for the unveiling of the Alpha 100. No-one anticipated being driven miles into the desert-like countryside of Oued Nfis for the experience of a night under canvas after witnessing feats of Berber horsemanship and a massive pyrotechnic intro!
