"you've virtually wiped out the advantage of medium format v's digital or 35mm."

Well to be fair I'm sure PeterH used 35mm as an example coz of it's portability and image ratio/shape (correct me if I'm wrong Peter), but I agree in detail and sharpness (and lack of noise) that digital has the upper hand at 22mp. Yesterday I was looking at 30mo stuff. The immediate future is really exciting, but not portable yet.

Ye gods I'm so happy to have digital 35mm and a battery that lasts 300 frames, it's like a dream to me, and up printed to 20-30 inches on Fuji paper is still stunning.

Way off topic aren't we, argh.

Here's something to imagine

I know that's in effect a massive stitch-up, but that's what 2.5 gigapixel sensor will be like one day, who knows?
