Note:

  • • Newer M645 Mount lenses designed for the Phase One system will not fit this adapter, only the older Mamiya-era M645 lenses will work with Fotodiox adapters properly.
  • • This is a manual adapter, so lens functions that rely on electronic communication with the camera body (autofocus, AE metering, image stabilization, etc.) will be disrupted.
  • • Some cameras need to be set a certain way to work with our adapters or you may get a message such as 'Error Lens Not Attached - Check lens'. Please check the support articles on the Fotodiox Knowledge Base for possible solutions on a variety of camera brands.
  • • 'Focus-By-Wire' lenses (such as Canon's STM or Nikons AF-P) requires power to engage the manual focus rings on the lens, since manual lens mount adapters do not power the lens, those lenses will not be able to focus.
  • • Set your exposure manually or meter using your camera's Aperture Priority (stop-down) mode.
  • • If your lens does not have a manual aperture control ring, the lens aperture will revert to its default position, which depending on the lens is either stopped down to its largest f-stop or opened up to its smallest f-stop.
  • • To determine what the new 'Crop Factor' or 'Equivalent Focal Length' of the lens when used on your camera will be, please check the Fotodiox Knowledge Base article.

Customer Reviews (5.0 / 5 · 5 reviews)

Isabella ★★★★★

The build quality is surprisingly solid for the price—the metal construction locks onto my Sony body with zero wobble. Infinity focus works perfectly, so my old Mamiya glass now focuses to the horizon without any issues.

Henry ★★★★★

I was worried this adapter might feel flimsy, but the metal construction is rock solid on my Sony body. Focus ring turns smoothly and infinity focus locks in perfectly every time.

Brian ★★★★★

Finally got infinity focus with my M645 lenses on my Sony body, and the tolerances are so precise that even the aperture ring turns with zero play. I’ve shot a full wedding with it and never once felt the mount flex or shift. Worth every penny for the sharpness it preserves.
