Hello everyone,

I would like to ask if there is any way you know Of to adapt mamiya 645 lenses to fuji x mount. And by adapter i mean with glass elements (speedbooster), not a plain adapter just to fit another mount.

<sorry, I see now this adaptor is for Sony - wasn’t able to figure out how to delete my post>

Is something like this what you are looking for? https://www.adorama.com/kabenexma645.html?gclid=Cj0KCQjwpPHoBRC3ARIsALfx-_J9AUFr19E-ozxexZkYqMnZZAvy1-1Kf8P4kixHtZOrzOXb8vbi9y4aAlUqEALw_wcB

Good luck,

I can't seem to find a combination of speedbooster + adapter, and definitely no speedbooster that does mamiya645->fujiX


There are 645 to EF and EF to X adapters... so you could do a double adapter to mount a 645, but making the medium format lens brighter on X doesn't seem to be possible.

How about:

Fotodiox  Mamiya 645 (M645) Mount Lenses to Canon EOS (EF, EF-S) Mount SLR Cameras; infinity focus or beyond allowed



Lens Turbo II


I use a similar set up on my Fuji.  I bought a slightly different Fotodiox Mamiya adapter but to Pentax PK, cut off the PK and changed to M42 keeping the same flange focal distance (PK and M42 are equal distance).  From here I added a M42 to FD adapter so as to fit my FD to Fuji Metabones Speed Booster.  Going the EF route above would be easier but FD to Speed Booster is what I had. (Yes, infinity is OK).  I wanted to use the excellent Mamiya 645 C 80mm f2.8 on my Fuji.  Now it acts as a light weight 90mm f2 on Fuji using only the sweet centre of the lens even when boosted.  Additionally on a dumb adapter I get a 120mm f2.8.
