This FotodioX Lens Mount Adapter allows an M42-mount lens without an aperture pin, or with a non-fully depressible aperture pin and tabs along its screw-mount, to be used on a Canon EF or EF-S mount camera. It is designed to support focusing to infinity and utilizes an aluminum-alloy lens mounting ring to provide a durable, yet lightweight camera-to-lens connection.
The leaf spring design in the adapter holds the lens tight to the adapter, mimicking the leaf springs in the camera body, ensuring there is no play between the camera and the lens. The all metal design and polished surface are designed to guarantee a smooth mounting experience for years to come. The depth of the adapters are designed to take into account the differences in focal flange distances between the lens and camera ensuring that all lenses, both brand name and third party, will focus at least to infinity (if not slightly past).

Generation v10 Focus Confirmation Chips
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.
Those old split prism viewfinders made a huge difference when focusing, kind of like your own phase detect focusing system.

Notes:
- 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'.
- 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.

Additional Notes:
Not all camera models and firmware updates are available for testing, some test results come from customer feedback
Focus Confirmation Chips do not support Canon EOS film cameras and should not be mounted to a film camera as this may result in short circuiting the film camera system (film cameras use older electronics that do not support this function).
Chipped adapters are not intended to be used on Smart Adapters that take EF/EF-s lenses.
