Canon lens to Pentax

zombiekilla · May 22, 2008

Im not sure if this is the right place and I searched all over to figure out were to put it, but I figured since Im new to photography and this is probably a newbie question Id ask it here.

I have a Pentax k100d and my father in law has a canon with some awesome lenses and he has said I could use them. Is that even possible? I'm pretty sure its not, but i figured I would ask you guys to make sure.

You would need an adapter.

I don't think Kmount adapters exist for FD nor EF Canon mounts... (and maintain infinity focus).

Sure...they do...

How about a link?

[Edit]

For EOS/EF, the issue is that those lenses don't have an aperture ring. Therefore, the adapter would have to interface the electronics driving the aperture ring with the electronics of the Pentax. I have never seen an adapter that complex.

For FD, the issue is flange distance. FD is 42mm while K-mount is a little more than 45mm.

Therefore a link to more information would be a lot more useful.

btw.. the other way is possible... mounting M42 lenses on either FD or EOS cameras.
