What puzzles me is why I would need to send the body in, too, since when I bought this lens, it worked perfectly on my 5DII. I had tried an AFMA on it, previously, but it didn't give me satisfactory results, being a zoom lens. I wasn't sure which end I should do the adjustment, so I left it as is. But, that wasn't a negative, since the lens was quite sharp without any adjustment.

So, now, I've got a lens that isn't what it was when I bought it, and all I would like Canon to do, is bring it back up to the specs that existed when I bought it, originally.
