I have a Pentax my with a zoom lens, and I also have a Canon AE-1 Program. which is my all time fave. I would like to use the Pentax zoom lens on my Canon. Is there an adapter to make that possible? And where would it be available? If item is possible, what would something like this run...or would it be cheaper to just buy a zoom lens for my Canon?

  • \$\begingroup\$ Do you mean a Pentax ME ? If so you would need a Pentax K to Canon FD mount adapter. I do not know of such an adapter available at present and cannot recall ever hearing of one. \$\endgroup\$ Commented Sep 22, 2017 at 23:46

    \$\begingroup\$ @StephenG, I'd say post that as an answer, rather than a comment. Regardless of which Pentax mount the lens might be, finding adapters to Canon FD rather than Canon EOS is going to be tough. \$\endgroup\$

  • \$\begingroup\$ @inkista If the OP confirms they have a Pentax ME (or specifies another Pentax K mount body) I'll post it as an answer. But now it's just speculative and I think it's inappropriate as an answer. \$\endgroup\$ Commented Sep 23, 2017 at 0:57
  • \$\begingroup\$ @Dawn What kind of Pentax camera do you have? There are a number of different Pentax mounts used by different Pentax cameras. \$\endgroup\$

1 Answer 1


It depends on the mount of your Pentax camera.

  • Finding a ready-made solution to adapt to Pentax K mount to Canon FD is basically not something you're going to find.

  • If you have a thread-mount M42 Pentax camera, then you can find adapter rings to FD.

  • And as there are Pentax 6x7 to M42 adapters, you could stack adapters if your Pentax is 6x7.
