Related Questions and Answers

Q: 1. I can't fit my 45mm 1:2.8 Mamiya Manual Focus lens on this adapter, though everything I've read says the lens should be compatible. Has anyone else experienced this issue? it fits into the adapter (aka sits in the grooves) but it will not click and lock.

A: If the FotodioX Pro Lens Mount Adapter for Mamiya 645, does not work with the 45mm Mamiya Manual Focus lens for the 645, that means it is defective, and because it has a 2 year warranty, it can be sent back to Fotodiox to get a working adapter.

Q: 2. 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: 3. 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. Using this adapter on the GFX and mating a Mamiya 645 35mm N lens, what would be the net focal length of this combination ? Would the net result be similar to a 21mm lens on a 35mm body?

A: No, it won't be nearly that wide. On the GFX 35mm should give you a 28mm field of view (if we are talking full frame equivalence)

Q: 9. Interesting. What Mamiya 645 lenses work with this adaptor? Only the latest digital lenses, older Mamiya AF film lenses, or even manual focus film era lenses? If they work, How do they perform image-quality wise in DX and/or FX modes?

A: The Mamiya 645 lens mount did not change over time so all lens will mount on the adapter. Please be aware, with the newer AF models, the adapter has no provision to adjust the f/stop as this was done through the AF 645 camera bodies. Generally speaking, optical designs for larger formats do not have the resolving power for a lens designed for a smaller format such as 35mm. You might find 35mm lens outperform medium format lens when viewed side by side. The reason being that due to the larger capture area, there was no need to render detail in a small area. One advantage of using a medium format lens on a smaller format body is the ability to use swings and tilts much like you would on a view camera.

Q: 10. Do you offer lenses for the axella system?

A: You can use any Horseman bayonet mount lens that is compatible with the Copal 0 and/or Copal 1 shutters.
