on August 27, 2006Very interesting, The sensor doesn't respond the same way as film did at the edges. Sensors like straight on exposure. I have 2 20Ds. The 5D is sharper, but does it really make much difference? Never forget, it's the image that counts.....

on August 17, 2006The corner darkening is very noticable in some of these photos. Does this have anything to do with the cos-4th law?
