Re: Calibrate or not bother?

The only possible reason I would disagree with the previous posters (just a bit) about not sending your lens in is because it started acting up after a fall .

Since your 7D and other lenses are all working together as they should, that makes me think that something got knocked out of alignment on you 15-85.

Me, I'd first go ahead and try doing an MFA anyway as suggested by the others, you've got nothing to lose but your time!

However, I wouldn't be surprised if you find some other issues once you do that, such as decentering. If it does MFA and is sharp edge to edge, and you aren't having any other issues with the zoom or IS or MF; then you've certainly dodged a bullet haven't you?

Was there any cosmetic damage? Did you notice how it fell? I've had a camera drop and go down a concrete staircase, and just magically hit the edge of the hood or land on the cushioned camera strap, not even a scratch!
