So the next question is how good are the very wide lenses on full frame
digital sensors? I don't recall seeing any coverage of that. Do we run
into the problem of not having "telecentric" lenses as Oly maintains?
Ooops! Faulty memory. I just went back and looked at the 1Ds review in
dpreview <http://www.dpreview.com/reviews/canoneos1ds/page16.asp> and
see that he points out some chroma at 28 and 17mm around high contrast
areas near the edge of the field. Also reminds folks that their full
frame lenses likely show some vignetting that doesn't show on a smaller
sensor. Well, I assume PhotoShop will deal with the chroma and the
vignetting if necessary.
