I just received a canon 135 f/2 from b&h and the autofocus seems really loud, kinda squeaky, to me. Not as bad as, say, my 50 f/1.4 but much worse than a 24-70 f/2.8 or any other L lens I've owned. Is this normal or did I receive a defective product?
Thinks Hiero. That sets my mind at ease. It's not so loud that other people take notice of it, so the noise itself isn't an issue, but I had worried that it was indicative of some other problem that might manifest over time if not addressed.
