Q: 1. Do we loose one aperture, like with a 1.4x tele-extender?

A: There is a loss of one (1) stop. It with electronic meters is is less an issue as it would be with an all manual camera. Bump up your camera's ISO 2x from what it is now to use this adapter.

Q: 2. How do I take it off??

A: The Fotodiox Pro Lens Mount Adapter for Pentax 67 Lens to Canon EF-Mount Camera, when mounted onto an EF mount camera, will release with the camera's lens release button. There is also a release knob on the adapter to release an attached Pentax lens.

Q: 3. The photos are confusing, what adapter am I actually getting. Are there two one that create the set?

A: Yes, there are 2 adapters that make up the connection from Pentax to MFT with a Canon EF adapter at the end. So basically Pentax 6x7 to EF and then EF to MFT.

Q: 4. I have a pentax k1000 SLR and my dad gave me his old Canon FD 50mm 1:1.8 S.C. lens. I would love to use this. Will this fit my Pentax?

A: Yeah. As long as it is an fd to a pentax k bayonet it should work. I have a similar canon fd manual lens 50mm 1:1.4 and it works fine. it is a bit confusing at first but mount the adaptor to the lens and make sure the canon lens is NOT locked in its auto setting on it's aperture ring. If you don't, the adaptor won't go on. Since its a manual lens you also have to do stopped down photography. It takes some adjusting but you get used to it.
