Aside from focal length and area coverage, that is. That would depend on the CCD sensor (and I'm far from knowledgeable on those) but since they are NOT film it is probably wise to say that they have different characteristics. They probably treat incident light differently and have different properties than the substrate of film. Remember we're talking about a silicon chip thatıs been doped and processed, not a silver-gelatin mixture on film. They may be more sensitive in one area of the light spectrum than another, but this could be corrected for in software. Of course a traditional lens will work. The CCD just might be happier with a lens designed for its specifications. I only know what I learned in my solid state devices courses, but we were focusing on the physics and structure of devices like this -- not their imaging properties. Mike
