The FotodioX Mamiya 645 Pro Lens Adapter for MFTis a high quality adapter that allows you to mount a Mamiya 645 mount lens to a Micro Four Thirds camera body. It features a brass construction with a stainless steel finish as well as the ability to focus to infinity. This works with a leaf spring system for a secure attachment.

This adapter will not allow for electronic control over lens functions. In order to function with automatic metering you will need to place the camera in manual or aperture priority mode, where the camera will utilize stop-down metering to determine the appropriate shutter speed.

Q: 1. will this adapter work on the K3II??

A: The K3ll uses the standard K mount lens, so the good news is all Pentax K lenses from the last twenty + years will fit directly. The Pro Lens Mount adapter will therefore also work for Maymiya 645 Lenses to mount on the K3lll.

Q: 2. I read the answer about the iq250, however would this also work for the IQ180? Remember the IQ180 has a larger sensor, so just curious if it will still work. Thank you for the previous answer as well, Ill definitely be getting the cables you recommended. IQ180 compatibility?

A: Yes , the FotodioX Pro Mamiya 645 Large Format 4x5 Adapter will work with the IQ180 as well.

Q: 3. 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: 4. Would this adapter allow me to use 645 lenses on a F2AS body? I am not sure about how the lenses would index, if at all.

A: Si puedes utilizar lentes de Mamiya 645 en cuerpos Nikon, el resultado es muy bueno, pero solo trabajan en modo manual, yo los utilizo en mi Nikon D 810 y estoy muy feliz.

Q: 5. Just bought, try my mamiya lenses I got back when I was in school circa 2002. The very first thing I notice when I attached to my Nikon D5100/5000 cameras was on the display as soon as you turn it on stated that their is no lens attached. I quickly realized I was on auto mode. When I switched to manual it still stated no lens attached. But I was able to shoot. But only the manual feature worked when I tried going to F-stop priority manual setting like I see suggested above it won't take a picture. I made sure everything was locked in. Curious if the only setting it can be used in is the manual M setting and not the F-stop priority manual or am I doing something wrong. Thank you

A: On the Nikon D5000 and the Nikon D5100 the FotodioX Pro Lens Mount Adapter for Mamiya 645 Lens to Nikon F Mount Camera could only be used in manual mode.

Q: 8. 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: 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. May I know is the Tripod mount removable for this adapter?
