The Pro Lens Mount Adapter for Contax 645-Mount Lens to Sony E-Mount Camera from FotodioX allows a Contax 645-mount lens to be used with a Sony E-mount camera. The adapter is designed to support focusing to infinity, is constructed from brass and aluminum alloy, and features stainless steel lens mounting rings to provide a durable yet lightweight camera-to-lens or camera-to-adapter connection.

This lens adapter does not support electronic communication between an attached camera and lens, so lens functions that rely on electronic communication with the camera body, like autofocus, AE metering, and image stabilization, will not function. To manually control the amount of light that enters a Sony E-mount camera when using this adapter kit, an integrated iris mechanism allows for approximate adjustments of brightness as well as depth-of-field.

Q: 1. Does this work with the Auto Mamiya-Sekor CS 50mm f/1.4 Lens?

A: This adapter is not compatible with the Auto Mamiya-Sekor CS 50mm f/1.4.

Q: 2. 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: 3. Will this adapter work with manual 645 lenses !?

A: The correct adapter for your 645 manual lenses is: FotodioX Adapter for Mamiya 645 Lens to Sony NEX Mount Camera BH #FOPNEXAM645 • MFR #M645-SNYE-PRO https://www.bhphotovideo.com/c/product/994963-REG/fotodiox_m645_nex_p_adapter_for_mamiya_645.html You can attach this adapter as well but you will be paying almost twice as much for it because the integrated control ring allows aperture adjustment on AF lenses. Mamiya MF lenses already has a built in aperture ring.

Q: 4. The reviewer states that the camera's shutter and not the lens's shutter is used. Can you provide additional operating details?

A: The leaf shutter has to be open in order to use this adapter.

Q: 5. Has anyone tried to mount this to Canon R6 through an EF-RF adapter? Is AF still functioning?

A: It is not recommended to attach two adapters together. And KIPON Lens Mount Adapter for Contax 645 Lens to Canon EF-Mount Camera has not been tested with a EF to RF lens adapter. Chances are it will not function at all or very well.

Q: 6. Will this adapter works with the Sony PXW FS7?

A: It works perfectly of my FS5 so I would say it will work perfectly on a FS7. :-) Naturally only with manual focus and manual iris.

Q: 7. Does this adaptor work with newer Phase One lens like the 80mm leaf shutter ? I have an adaptor but only takes the old manual lens I have a new Hartblei 45mm TS which is full manual but has the newer mount flange. Any help would be great as Fotodiox don't come back to me on this question.

A: Hello Lea,Unfortunately, I cannot tell you if it works with Phase One lens. I have only old manuals lens. It works well with them.

Q: 8. Does this work with the A7II?

A: I use this with an A7R and several Mamiya lenses, they work great. Just remember auto focus and auto aperture do not work, you must use manual mode. You can use aperture priority mode if you want the camera to set both ISO and Shutter speed. Use Peaking Level to assist with focus, may need to keep the aperture open to get light to focus. Also set Zebra on to help with exposure. Fit of the adapter to both lens and body has been snug with no movement or wiggle. I plan to add several more used Mamiya lenses

Q: 9. Is the 645 format a standard like MFT? Meaning, is the Pentax 645 the same mount as a Mamiya 645? Will this adapter work with Mamiya or Schneider-Kreuznach lenses that use the Mamiya 645 mount on Fujifilm GFX cameras? TIA.

A: The Pentax 645 and Mamiya 645 offer the same film format, but with different mounts for their respective lenses. This adapter accepts Pentax 645 lenses that originally worked on the Pentax 645/645AF medium format film bodies or 645Z medium format digital body.

Q: 10. Does it works with Pentax smc FA 645 80-160mm f/4.5 Lens on X2D?
