    Note:

  • • 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.

    Lucy ★★★★★

    I was a little worried about compatibility, but this adapter locks onto my RB67 lenses perfectly and the focus ring moves smoothly. Being able to hit infinity focus on my Pentax body is exactly what I needed.

    Ruby B. ★★★★★

    The built-in focusing helicoid is a lifesaver for adapting old Mamiya lenses to my Pentax body—I was worried about losing close focus, but this adapter handles it perfectly. Sharp results at infinity too, which is exactly what I needed for landscape shots.

    Evelyn V. ★★★★★

    Finally got my vintage RB67 glass working on my Pentax — the integrated focus control dial is a game-changer for precision adjustments. Build quality feels solid and everything locks in tight.
