    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.

    Christopher ★★★★★

    The all-metal build feels incredibly solid in hand, and I’m impressed that it maintains perfect infinity focus with my M645 lenses on the Sony body. No wobble, no light leaks—just a smooth, precise fit that makes adapting medium format glass a joy. This adapter turned my old lenses into sharp new to

    Emily ★★★★★

    I was pleasantly surprised that it locks onto both my Mamiya 645 lenses and the Sony A-mount body with zero play; infinity focus is spot-on, which isn't always the case with adapters. The hardened metal construction feels reassuringly solid, too.

    Timothy C. ★★★★★

    I was worried about losing infinity focus with vintage lenses, but this adapter locks on perfectly even at f/22. The all-metal rings fit my Mamiya glass and Sony body snugly with no wobble.
