Q: 10. Can I change lenses on the adapter without removing the adapter from the camera? I know the directions say to remove the adapter from the camera first, but I would like to know why.

A: Yes, Canon Drop-In Filter Mount Adapter EF-EOS R with Circular Polarizer Filter has a lens release switch to remove or interchange lens on the Canon full-frame mirrorless cameras. Canon recommends removing the lens and adaptor in the first step as a safety precaution. Also is assume that you are removing the lens to put your camera away instead of switching lenses in the field. There is no harm caused to the camera or adaptor if you keep the adaptor on the camera and remove just the lens.
