Your missing the point: of course it would work with film. Moving the rear element away from the film just means the "beam" from the rear element would be designed to converge more slowly than before. It would still come to focus on the same plane. As a direct consequence, as Jim said, the lenses would have to be bigger / heavier. I'm still confused as to how the 1Ds seems to cope fine edge to edge yet <TROLL> the poxy little sensors of amateur versions </TROLL> are bothered by the comparatively small angular variation. Why didn't they make the sensors curved and be done with it ;o) B * **** ******* *********************************************************** * For list instructions, including unsubscribe, see: * http://www.a1.nl/phomepag/markerink/eos_list.htm ***********************************************************
