The problem is that the lens to focal plane distance for the FDs is shorter than that of the EOS lenses to focal plane, so unles syou are willing to shorten the lens - and it has been done, then you can't just stick them on an EOS camera.

I have a 28 f2.8, 50 f1.4, and 100 f2 FD lenses - and they are useless on an EOS.

I have thought of modifying them, but it takes a lot of skill and time to do this. You have to remove the mount part of the lens, shorten the barrel and fit an EOS mount on it... Not easy.

You can also get adapters - basically 1.4x teleconverters. Adorama has them http://www.adorama.com/ or http://www.adorama.com/CZFDEOSA.html and so does B&H http://www.bhphotovideo.com/

I bought a B&H one, and it works OK, but you lose a lot of definition and you need to stop down to f4 or so, otherwise ithe images are crap.

The reason I originally got the 100 f2 was because it is such a sharp and fast lens. On the EOS it is a mediocre slow lens....

As for any other lens - Nikon, Pentax, Olympus, Contax, Leica, you name it, you can get a $20 adapter and they all work fine on an EOS. Just old canons are crap on new canons....

If you want to go EOS, film or digital, put the FD lenses on a shelf and look at them wistfully sometimes and just go and buy a new EOS lens.
