You really need to do a little searching on your own, but here's a link to assist with this question: http://en.wikipedia.org/wiki/Lens_mount . Basically any lens which has a longer flange mount distance than the FD can theoretically be mounted on it via an adapter and focus to infinity. I routinely use adapters to mount Nikon, Tamron and Leica R and Leica M (Visoflex) lenses on my FD cameras. Of course they must meter stopped down, hich is sometimes a pain. There are lots of adapters on Ebay.
