FD to EOS R Mount Adapter, Compatible with Canon FD/FL Mount Lens and Compatible with Canon EOS R Mount Cameras
SKU: KF06.378
Q
Why doesn't it work with canon rp?
Answer Question
A
This is a manual lens adapter, it won't work with autofocus lenses. If you check the base of your EF/EFS lens you will see multiple gold electrical contacts but the K&F Concepts lens adapter does not have any of these. Hence it is unable to pass signals from the camera to the lens. The product description says, "As Canon's EOS lenses are electronically controlled,most Canon EF mount lenses do not feature a manual aperture ring,so when used on our EOS-EOS R, which is a fully manual operation adapter ring, the aperture could not be transferred to the camera, it will stop down to its smallest f/stop by default."
