    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.
  • • To remove the adapter, move the release lever (circled in red) in the direction of the red arrow:

    Jason Q. ★★★★★

    The aperture dial is a lifesaver—I can finally control exposure on my old Pentax glass without fiddling with adapters. The mount feels rock-solid on my camera, and infinity focus locks in perfectly for landscapes.

    Aurora ★★★★★

    I was worried about losing aperture control with my old Pentax glass on my Sony body, but the built-in dial is surprisingly smooth and precise. The fit feels solid, no wobble at all, and infinity focus works perfectly. Exactly what I needed for adapting my vintage lenses.

    Natalie N. ★★★★★

    The aperture control dial on this thing is a lifesaver for using my old K-mount glass on my Sony—no more fiddling with stop-down metering. Infinity focus is spot-on, and the fit is snug with zero play. I've shot a whole weekend with it and haven't felt the need to take it off once.
