Photoclub Alpha

Increases in pixel count are often dismissed because to ‘double’ the resolution of a 6 megapixel sensor you would need 24 megapixels. Indeed, to double it linearly you would - but the human eye judges density of detail on an area basis.

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.

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!’…

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.

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.

I SELL digital images through Alamy, the on-line photo library. When an original piece of art is out of copyright, and displayed in public or by an owner permitting photography, the ability to get a good quality reproduction copy on the spot without lights, tripod or flash is valuable. Some 8 per cent of my overall Alamy images sales over the past four years have been of signs, notices and labels - disproportionately high, compared to the actual number of such shots. As someone has commented, editors like pictures which tell their own story, and sometimes have words in the pictures does just that.

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!
