    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.

    Benjamin ★★★★★

    This adapter preserved infinity focus on my old Pentax 645 lenses, which was my main worry when switching systems. The high-tolerance construction makes every lens feel like it was meant for the MFT mount—tight and precise. Exactly what I needed for adapting this glass.

    Charlotte ★★★★★

    The fit onto my Lumix body is rock-solid with zero play, and I love that it still allows infinity focus with my old Pentax glass. Image quality through this adapter looks sharp corner to corner, no noticeable degradation. Really impressed with the precise machining.

    Ella N. ★★★★★

    I was worried about light leaks or a loose fit, but this thing locks on with a satisfying click and allows infinity focus beyond what I need for landscape work. The tight tolerances mean my old Pentax 645 glass finally feels native on my M4/3 body.
