This FotodioX Lens Mount Adapter allows an M42-mount lens with a fully depressible aperture pin 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.

A Generation v10 chip built into the adapter enables focus confirmation within a Canon EF or EF-S mount camera when used with a compatible M42-mount lens. This feature allows focus to be quickly and accurately achieved through a compatible camera's viewfinder or live view feature.

A: Even if one were to test it today, firmware updates to the camera could enable or disable that feature at any time. As with any third party accessory of this type, if you find such a feature to be both functional and essential to you then you'll want to avoid updating the firmware before you're able to ascertain from someone using the new firmware whether or not they consider its performance satisfactory. As of the time of this writing (June 2021), we do at least allow 30 days to return this product with all included packaging material if its performance is in any way unsatisfactory to you.
