Is it possible? I've seen lots about using FD lenses with EOS cameras, but can it be done in reverse? My Canon 7e is busted and I've got my eye on a T90 for cheap. Does anyone know of a method of adapting EF lenses to FD? I've never actually used an FD mount, so if this is an entirely preposterous question, sorry. I don't know much about the actual size of the FD vs EF mounts, and it may be physically impossible. Thanks for any input.
