I just received my RF 85mm f2 macro lens and got excited clicking tiny things around the desk. The focus range limiter switch is a tad stiff. Perhaps it will become better with use. However the one thing that piqued me was this low grade constant buzz sound from the lens. I turned off the IS thinking it was causing the sound (My old EF 70-300 makes a racket when IS is on) but that didn't stop it. I also turned off auto focus on the lens. That didn't help. The sound does not seem to change much, like when during IS or focusing. It just seems to be constant. Can leave the camera with lens on the desk and still hear it. Is this normal? Does anyone else notice this? I don't want to return this as I can't seem to find it stock.

I have the same stiff focus range limiter switch problem as you—it was so stiff I almost returned my copy. Better than a switch that’s too loose and could be budged by accident, I guess.

As for the buzz sound, it’s there on my copy as well, but it isn’t audible even in a silent room unless I bring my ear close to the lens.
