An interesting point about film but I think it is not the case that digitally optimised lenses are better quality it depends what you mean by normal? For example Canon do not make a L series lens in the EFS mount which are digitally optimised, the point is that they can be made smaller and so less expensive glass is needed in theory they should be able to make them better or as good but no doubt the big makers are not interested as it would require enormous investment.. And in the end they have the full sized 1DS etc as the main pro camera which has the same 35mm frame which is standard unlike the 1.3 1.5 or 1.6 sensors on the best digital SLR
