The FotodioX Mamiya 645 Pro Lens Adapter for Fujifilm X-Mount Cameras is a high quality adapter that allows you to mount a Mamiya 645 mount lens to a Fujifilm X-mount 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 of the lens to the adapter.

Although the lens will fit physically, automatic lens control and functions will not operate correctly while using this adapter. You can utilize aperture priority mode in combination with stop-down metering for automatic exposure control on your camera.

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. Is this adapter only for macro use ? and will effect the focal length of the lens when used for general photography ?

A: No, the FotodioX Mamiya 645 Lens to FUJIFILM G-Mount GFX DLX Stretch Adapter is not only for macro photography. It features an integrated focusing helicoid that provides close-up focusing when desired and can be retracted for guaranteed infinity focus during general purpose shooting.

Q: 5. 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.
