Mirrorless cameras aren't only revolutionary because of their compact size; they're even more versatile for mounting lenses than their full-sized counterparts! Whether you're shooting digitally or on film, Fotodiox offers the world's largest selection of lens adapters with strong support for mirrorless camera platforms with hundreds of options for mounting both modern and vintage lenses. Mix camera/lens platforms or reinvigorate vintage glass; our adapters deliver manual aperture control and a sturdy build for lasting quality.


One of the problems of using manual focus lenses on Canon EOS bodies is that focus confirmation is disabled. When AF lenses are used - even in manual focus mode - all Canon EOS bodies confirm focus with a green dot in the viewfinder and an (optional) audible beep. However when non-EF compatible lenses are used via an adapter, the focus confirmation is disabled. Unless the camera thinks that an EF compatible lens is attached to it, it switches off both visual and audible focus indication. Focus confirmation chips 'trick' the Canon EOS body into thinking an EF lens was attached, so that the focus confirmation indicators work with any lens attached. Focus confirmation chips are great because:

  • • Without live focus, all that is available is a smooth dim viewfinder
  • • Even with live focus screen it's really hard to see when focus is properly achieved on the subject you want.
Pro Tip: Split prism viewfinders made a huge difference when manually focusing, kind of like your own phase detect focusing system.

Putting old lenses onto new, high-performance DSLR or mirrorless cameras seems counter-intuitive so why would anyone want to? The simple answer is that many older lenses can capture images that have that elusive quality known as character. For photographers or videographers who want to create unique images that express their personal style, character can be even more important than resolution numbers, corner-to-corner sharpness, and other advantages of the near perfect lenses that are quite common today.

The imperfections and aberrations of older lenses are the very strengths that set them apart from modern lenses. Additionally, a fully mechanical lens is likely repairable longer and less expensively than modern focus-by-wire lenses. Old lenses also let you change camera systems, or your mount can get retired and your lenses won’t be bricked. At the extreme case, some mirrorless lenses require firmware updates for every new body, so even if the mount stays around lenses won't stay on that update list forever (for instance Nikon's new E lenses are incompatible with cameras just two generations old).

The Fotodiox standard adapter is the perfect purchase for anyone who’s new to using adapter systems or doesn’t switch their lenses often or are using off brand lenses that may not have been machined to the exacting specs of the mount they were designed for. An affordable alternative to our Pro adapter, these adapters can be adjusted to prevent light leaks and ensure the perfect fit.

Fotodiox adapters feature all-metal, no plastic construction to create a secure connection between your glass and camera that will not degrade over time, keeping the lens-camera connection secure with every use. We use metal mounts for durability and reliability. All Fotodiox products are backed by our 24-month Fotodiox Manufacturer Warranty.

  • • Limited focusing range, macro work only (will not focus to infinity), great f/ close-up work. Due the difference in Focal Flange Distance between the lens and camera, this adapter will not allow the lens to focus to infinity. Visually focusing using the viewfinder or camera screen is the best way to ensure proper focus - not the distance markings, as they will not match up 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 Knowledgebase Center for possible solutions on a variety of camera brands.
  • • 'Focus-By-Wire' lenses require 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.
  • • All pictures are for illustration purposes only. Actual product may vary slightly due to ongoing improvements in design.

David ★★★★★

Finally got my old CCTV lenses working on my Canon DSLR, and the focus confirmation chip makes manual focusing a lot less frustrating. The adapter itself feels solid and clicks into place securely.

Riley ★★★★★

The focus confirmation chip on this adapter locked on faster than I expected with my old Helios lens, though it’s a bit finicky in low light. It feels solid and gives my footage that vintage character I was after.

Charlotte W. ★★★★★

The focus confirmation chip is spot-on with my Canon body, so my old CCTV glass finally locks focus without the usual squinting at the screen. Built solid too, no wobble or play when I torque the lens on. Exactly what I needed for adapting these vintage lenses.
