Compatible Canon RF mount mirrorless cameras include: EOS R, EOS RP, EOS R5, EOS R6 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. '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.
