Sure, but Canon no longer make any bodies with an FD mount. You have to buy second hand bodies if you want to use a Canon FD lens, or buy an adaptor, or a mirrorless digital camera, unlike Nikon or Pentax. Were Canon's mount problems insurmountable (sic) in an autofocus age? I'm not enough of an engineer to say. Nikon have gone through various incarnations of manual and digital lenses through half a century, and with a few exceptions, most can be adapted to operate on modern cameras.
