Ironically, the 20D has absoluetly no issues with mounting M42 lenses via an adaptor, just like Pentax. Nikon F mount is also quite doable, along with Leica R, Contax/Yashica and OM mount. Of the major mounts only FD, MD and Minolta AF cannot be adapted with a plain adaptor (K mount can be adapted with a plain adaptor to EF-S, and if the aperture lever is trimmed, to all EF via a very new adaptor or Cotty's mount replacement procedure).
I've personally used M42 and F mount lenses on EF when I had my EOS 3. -Adam Lucas Rijnders wrote: > Op Fri, 14 Jul 2006 11:18:21 +0200 schreef Christian > <[EMAIL PROTECTED]>: > > >>Lucas Rijnders wrote: > > >>>No: Canon Fd register is shorter than EOS, so with an adapter you either >>>loose infinity focus, or you need an optical adapter: essentially a weak >>>TC.
