Hi Peter, I'd agree and I think that most anyone who has a wide-angle lens and used it on both a film and digital body would agree. Wide angle images do not seem to be captured as well on current digital bodies as on film even using the same lens. I have seen this myself with my EOS 1D and EOS D60 bodies. It seems to be more of an issue with the D60 than the 1D for some reason. The only thing I can come up with is the fact that the 1D photosites are much larger than those of the D60's sensor. I'd like to know how these new "digital" lenses work. The problem with wide angle lenses and digital sensors from what I can tell has to do with the angle that formed image photons hit the sensor's photosites. Logically (to me anyway), it would seem the only ways to improve this issue is to redesign the sensors (which a new lens can't change), or to change the way the image is being formed on the sensor by reducing the angle of incidence (for my lack of a better term), that photons strike the photosites. Have you seen the rear elements of these new "digital" lens designs? If this is what they are doing the rear elements should be huge and set far from the sensor yes?
