Q: 1. Will this adapter work with Phase One Schneider lenses and allow full apeture control? I understand that focusing would be strictly manual. Thanks.

A: If you own a Phase One Schneider Kreuznach old lenses you can attach KIPON Baveyes 0.7x Lens Mount Adapter for Mamiya 645-Mount Lens to Sony-E Mount Camera to your lenses. There is no aperture control on the adapter. The lens would be set to wide open aperture. For new Phase One lenses I wold recommend speaking with Phase one regarding changes on their mounts. We provide 30 days satisfaction if you can not get an answer from Phase One.

I bought a different brand from a local dealer, but the slightest touch of the release button and the lens comes off!I'd like to know if the FotodioX one is more secure.Thanks.

Q: 3. Does this adaptor enable autofocus of the Mamiya lens (as long as the lens has autofocus capabilities of course) ?

A: No, the KIPON Baveyes Lens Mount Adapter for Mamiya 645-Mount Lens to Canon RF-Mount Camera is purely a manual adapter. There is no communication between the lens and the camera with this adapter. All aperture and focus control would need to be done manually on the lens.

Q: 4. Mamiya 645 Lens covers the full frame on the A7S II with this adapter?

A: Hi Dave,I did some tests on the A7R; A-900; Nikon D700. As you know - all of these are FF. The Mamiya 645 with this adapter covers approx. 156% of the sensor. You will experience ZERO light fall-off, even when fully stopped down (at highest f-stop). Mamiya 645 lenses are fantastic - so enjoy - it opens up a totally new world of excellence. If I may - just one word of sound advice. Due to the resolving power of the lens, and the high pixel density of the sensor, I advise that ALL shots with 645 lenses are done using a sturdy tripod. Even at high speeds, getting a pin sharp photo is VERY challenging. During 2015, I've done approx. 12000 shots with my 645's, with in excess of 90% on tripod. Of these, the rejection rate is approx. 7%.Kind regardsJohannes van GraanCenturionSouth Africa

Q: 7. Would the field of view for Contax 645 80/2 lens on a Canon full frame camera change? Would it become 120mm? Thanks.

A: The Canon 645 80mm lens,using the KIPON Lens Mount Adapter for Contax 645 Lens to Canon EF-Mount Camera, would have the field of view of an 80mm lens on a Canon full-frame camera, which would be a short telephoto focal length, rather than the "normal" focal length it is on a 645 camera.

Q: 9. Hi, does this adapter allow me to control the lens aperture on Pentax 645 FA and D-FA lenses.I cannot quite see by the photos if this is possible.I assume that you can turn the outside of the adapter to adjust the aperture.Please confirm.Many thanks, Scott

A: When using the FotodioX Pentax 645 Pro Lens Adapter for Canon EF-Mount cameras, if the lens has an aperture ring, you can adjust the aperture manually.

Q: 10. Will this adapter electronically close the aperture of Mamiya 645 AF lenses? I.e. for the newer lenses without an aperture ring- If I shoot with my Schneider 150 LS at F/16, will the sony body close the lens to F/16, or can I only shoot it wide open?

A: You would need this version for a 645AF lens: https://bhpho.to/3xc5L1J This adapter does not support electronic communication between an attached camera and lens. To control the amount of light that enters a Sony E-mount camera when using this adapter and a Mamiya 645 AF/AFD lens, an aperture-control ring is built into the adapter which couples with the lens's aperture mechanism so that adjustments to brightness as well as depth-of-field can be made.
