I feel it´s a pity that DSLR designers stick to Oscar Barnack´s 1914 decision to use 2:3 instead of taking the opportunity to use a more harmonic 4:5. But that´s an aside thought... Per I agree. I find 2:3 a bit too "long" and generally end up cropping for width. The problem I didn't think of till recently is that most of my lenses (well, the shades anyway) would no longer work. Since many of us have more cash "invested" in lenses than camera bodies it would have been a brave DSLR maker to go that route. I can't be 100% about whether all SLR lenses could be adapted to use a "full frame" 4:5 image circle (that is, not a 2:3 one cropped down) but certainly the very wide ones I have seem to have internal "baffles" which might stop that. Now when Canon standardised on the APS sized sensor used in the D10 (their press release at the time hinting they were not going to be developing any new "full frame" 35mm SLRs) that was closer to the format you suggest and does indeed have new dedicated lenses. Now they have the D5 :o) Bob
