Dunno about snobbery but I did read the Rodenstock article recommended by Jim and an interesting piece it is: it describes quite thoroughly why ordinary good quality photographic lenses are not good for digital photography.
It fails, however, to describe why the said lenses are good for digital photography. This is a failure, because ordinary good quality lenses are successfully used - and Rodenstock seems to be the only optical company implying that inferior optical quality gives better quality digital photographs - and even they do not explicitly state that their Digtar lens line actually is inferior. The other company having introduced lenses for digital photography - Sigma - only says that these lenses have better evenness of illumination suitable for digital photography and shorter focal lengths with larger apertures. Nikon, Canon, Contax support their normal lens lines, so did Pentax. And Kodak Pro Back uses Hasselblad body and lenses, not known for poor resolution or contrast.
Aliasing is a problem in digital photography but it can be dealt with. And CCD development is so far from theoretical limits that the chip that makes Leica lenses usable for Rodenstock style - as opposed to more practical approach - digital photography probably is not very far away. In the mean time somebody should put his/her Leica/Canon EOS lens adapter to work and try Leica lenses on a digital EOS. I´d bet that the results would not be bad.
BTW I read from another list that the problems with the Philips 24x36 CCD chip are not in the chip itself but complex programming it´s use requires - and price. Might be true?
All the best!
