    • Mirrorless cameras aren't only revolutionary because of their compact size; they're even more versatile for mounting lenses than their full-sized counterparts! Fotodiox offers strong support for mirrorless camera platforms with hundreds of options for mounting both modern and vintage lenses. Our adapters deliver infinity focus, manual aperture control, and a sturdy build for lasting quality. This macro adapter allows you to extend the lens from the camera body giving the ability to focus closer than normal as well as correct for any possible back focus the lens may have, in effect this adapter acts like a small built-in bellows.

  • • 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.

    Evelyn P. ★★★★★

    The built-in focusing helicoid is a game-changer for adapting old M42 lenses—I can fine-tune focus down to a few centimeters without any extra gear. It locks onto my Sony body with zero wobble, and infinity focus works perfectly for landscape shots. One of my favorite cheap photography upgrades this

    Joseph Y. ★★★★★

    The built-in focusing helicoid is a game-changer for adapting my vintage M42 lenses, letting me fine-tune focus well past infinity. It threads on smoothly and feels solid on my Sony body, no wobble at all. Exactly what I needed to breathe new life into old glass.

    Claire ★★★★☆

    The helicoid ring has a nice, smooth resistance for precise micro-adjustments. It feels solidly built and works perfectly for adapting my old M42 lenses to the Sony body. Only wish it came with a lens cap for the mount side.
