Any EF mount Canon lens going back to 1987 can be used on any current DSLR with full functionality. Canon introduced the EF mount in 1987 as an upgrade to their previous FD mount which was fully mechanical and had no provisions for auto focus. The EF lenses have the auto focus motor mounted in the lens and the only connections between the body and the lens are electrical.
Nikon actually went through similar upgrades in their past. Lenses older than 1977 can't be used on current bodies without modification. Even after the modification, there won't be any auto exposure.
