Digital lenses as far as I can determine have there image forming cone optimised to cover a smaller area and often offer FL ranges not covered by regular 35mm lenses. They may also be designed to have a longer effective secondary principal plane in order to reduce the angle of incidence on the sensor?>
It seems to go back to the "old" arguments of lens colour. It has been held that the German lenses are "warmer" than the Japanese. In colour negative films, the manufacturers have been corrected (or enhanced) the emulsion to render the sky blue without the need of a UV filter. The reason being that the main market is the point and shoot crowd. For that reason, my lenses are "naked" for negative films and use a UV for transparency materials. A lens for digital IMO is one that coverage for the smaller format and probably unusable for 35 mm. However, a 35 mm format lens may provide too much coverage and degrade the image due to flare.
