Also a mount with a wider flange than any other 35mm system, and even THEN a shorter flange distance (lens to film) than Nikon, Leica R, or Contax -- so you can use any of those mounts on an EOS with an adapter... though not FD lenses, which had been made for the very narrow FD Canon bodies.The upside for Canon was that they had a lensmount system optimized for autofocus.
