There is also an SA control ring which thankfully has a lock so you don't accidentally hit it and affect your image quality unknowingly. One control ring can be programmed to adjust any setting you might want (e.g., aperture, shutter speed, etc).

: Canon EOS R5 C training series is released. I can't tell you exactly where to look, but I don't doubt that one of the other regulars will be able to help you. Obviously this requires a certain degree of finesse, but the procedure has been described several times in the forum.
The cure that often works is to forcibly manhandle it back into position. The usual cause is trying to focus manually while the lens is in AF mode. Unlike the situation with the OP's macro, this sounds like one of those cases where the autofocus motor got stuck. I didn't see any more replies and was hoping for an anserw since I have yet to find any others with the same problem. I hope it's okay to jump on someone else's post. I have 3 other lenses and these all work fine so i know it is in the lense, not the camera. Sporatically it will find focus and stop but most of the time it goes on for as long as I hold the button in. When I have it on auto focus it just keeps going in and out. I can manually focus and the red lights show when I push the button half way in. I have a canon rebel xs with the 18-55mm lense and is doing the same thing.
