I could see a lens for digital cameras needing better anti-reflection
on the rear element because a sensor is more reflective than film.
The differences that I've heard are that film has the different colors
on different layers, where with digital you need all colors to focus
in the same plane. I've also heard that digital sensors are more
sensitive to the angle of incidence of the light rays striking them.
One up for the Foveon sensor that has the colors layered like film ... I
guess.
