A universal digital back?

I’ve read an almost similar quote in the past already, and in fact it was partly the reason for me to get into the mirrorless µ43rds system. But it’s even more true for the Sony A7 family with their “full frame” sensors which almost have the exact same size like 135 film used to have. To quote Giles about it:

“So , if you are familiar with mirrorless cameras, they aspired to become a universal digital back, because their short distance to flange allowed them to accommodate any FF35 lens, with no need to correct the crop factor which other systems have (as high as 2x, in the case of m4/3) with a focal reducer.”

(from his article in “Sony A7, or the Lego FF System“)

Right. The price, body-only of the basic A7 (24MP) model here in Germany is 1230€ (at Amazon and others, partly with free shipping). And I would have a really good Olympus OM 50mm/1.4 which would be very nice to have on such a camera.

Those 50mm lenses on the “Pens” (I used the OM Zuiko 50mm/1.8 at f/5.6 here, hand-held at 1/8 of a second at ISO 800, which wouldn’t have been possible on these Sony cameras, since they don’t have image stabilization built in. So using these I would have had to use an even higher ISO setting, or a tripod. Cropped to 3:2 format during post to get a feeling for that other format again.)

My brother Willi has a Canon FD 50mm/1.8, a Canon FD 24mm/2.8, and a Sigma Zoom with Canon FD mount which would also be very nice when used with such a non-crop digital sensor. Both the resolution and also the dynamic range couldn’t be met with smaller systems like APS-C or µ43rds, which makes that thought a very tempting one indeed. That new Sony system doesn’t have all the native lens options that Canon or Nikon have for their DSLRs, but as a mirrorless system with a built-in electronic viewfinder at an even lower price than these older DSLRs, the Sony would be superior at least when used with these “legacy” lenses anyway.

Thinking about it since a while already…
