Mamiya 645 Super

[Brass] This is a barebones way to put a Mamiya 645 lens on a Fujifilm X series camera. I was afraid it wouldn't adapt the lenses from my 645 1000S, but it did, and it works like a charm! No circuitry for autofocus or zoom, and the rig is humorously large, but I'm getting great images. Perfect for those willing to devote themselves to a fully manual shooting experience. Fits right, and works as it should!

[Brass] This is the only adaptor I know of that makes Mamiya 645 C type lenses usable on Nikon SLRs and DSLRs. I have five of them and am glad I can use the on the DSLRs.

[Nikon 1] I have been searching for quite trying to find one of these mounts. I have several Mamiya 645 lenses in my kit - the Mamiya - Nikon mount allows me now to take full advantage of my CCD cameras that I use to take astrophotographs in wide field.

[1.5 lb] Have used this to connect a Mamiya 645 fisheye to a GFX100 and it works fine, easy to remove and add the adapter.

[0.05 lb] I use this on my Mamiya 645 80mm 2:8 as I have 62mm B&W 10 stop and 3 stop ND filters. It works perfectly...the filters screw in effortlessly. This is exactly why I buy B&W products. When I am shooting in the field, I do not want anything less.

[1.155 lb] Bought this to use my mamiya 645 lens I still have from the 1970 era have a 80mm and 210mm both work great.

[0.75 lb] Good fit. Allows use of my Mamiya 645 zooms center sweet spot on a Sony full frame. I already used it as a manual lens, so having only aperture priority exposure is fine. Prompt shipping, too.

[Canon RF] Fantastic addon for my Komodo. Wanted a booster to play with my Mamiya 645's, and not disappointed at all. Perfect!

[Brass, Aluminum] I tried 3-4 different Mamiya 645 lenses to Fuji G mount adapters, including the expensive ($475) Novoflex adapter. I found this FotodioX adapter the best. Here are the reasons: #1, It is well made, with a pretty good fit. It is not perfect, but there is only a barely perceptible play. I'd rather have it that way than it being too tight, which would be wearing out either my lens or my camera mount or both. #2, it comes with its own ARCA-compatible foot for tripod mounting. Don't underestimate this! This is very helpful, especially if you use heavier lenses. #3, the inside of the adapter is finished well in a dark, non-reflective coating, so I don't have any issues with reflections, flare, etc. My use case: GFX100S + Schneider Kreuznach 120mm Tilt/Shift for the Phase One XF camera (which is where the Mamiya line eventually ended up). My only gripe, which is not really a negative: I use the Fuji metal grip that extends the body of my GFX100S and gives me a better grip on the camera. With this on, the tripod foot on the adapter becomes too short - I can't mount it into my tripod without the lower edge of the camera running into an obstruction. So I would need to remove the bottom plate before I can put this on a tripod. I could still mount it with the base plate on, but it won't be centered in the clamp (which BTW, is not a problem, as long as I secure it well). Either way, it is not a big deal, and there is actually a positive side to having a short tripod foot: it leads to better stability. So no complaints. Net-net: I highly recommend it to anyone planning to use a 645 lens with their Fuji G-mount camera.

[Leica L] I recently purchased a Sony A7ii and instead of buying new lenses for it I bought this adapter and am able to use all my Mamiya 645 Sekkor lenes and they work perfect with it and look fantastic, for only $50 bucks I added 5 lenses to my arsenal
