Hey guys, sent my 5DII into CPS for the first time for clean & check, along with my 70-200II. The 70-200 is making a very slight grinding sound when it focuses. When the lens was new it focused silently. I also feel like my 70-200 is missing a bit more and isn't as sharp wide open as it used to be. Perhaps I removed the 70-200 from the body while the IS was still active? I remember the manual saying that could damage the lens. But that's all I can think of. I'll let you know how it turns out.
Last time I sent something to CPS it was a 580EX with a blown bulb, they kept it for 2-3 weeks and then told me they were tired of waiting to get the parts in to fix it, so they sent me a 580EXII, nice upgrade, I think they charged me $82.
