This link may help you understand the effect of lens crop. Like Donald says a 50mm lens is a 50 mm lens whatever camera it is on, the difference being that on a 10D etc not the entire lens is used therefore giving the effect that the lens is of a longer focal length than it actually is As I understand it this means that a percentage of the outer lens view is not used (what a waste of quality glass)
