Which lenses are compatible with this adapter?
This adapter is designed to mount Canon EF and EF-S mount lenses on EOS R series mirrorless cameras. It is compatible with most EF and EF-S lenses, both autofocus and manual.
Does the adapter affect image quality or autofocus?
The adapter maintains electronic communication between the camera and lens, so autofocus and stabilization (if the lens has it) work normally. It introduces no optical elements, so it does not degrade image quality.
What is the control ring and what is it for?
The control ring is a rotating ring on the adapter that you can customize to quickly adjust parameters such as aperture, shutter speed, exposure compensation, or ISO, according to your preferences. It works similarly to the control ring on native RF lenses.
Does this adapter work with EF-S lenses?
Yes, the adapter is compatible with EF-S lenses. When mounting an EF-S lens on an EOS R camera, the adapter maintains the focal length and angle of view, although the camera may automatically crop the image to fit the smaller image circle of the EF-S lens.

Light marks from normal use. Optically clean and fully functional.
Visible signs of use (scuffs, marks, brassing). Works perfectly.
Not guaranteed for use: sold for parts or repair.
Why buy used?
