Doesn't Canon ask you for the body as well when you send in a lens for "recalibration"?


I read somewhere that front-focus / back-focus issues can only be resolved when you have both the lens and the body, and that they may be able to correct it for that lens/body combination - but your other lenses may perform differently after the adjustment. That's what's so great about bodies with the micro-adjustment feature - you can do it yourself.


I guess maybe for soft corners and other problems they can work with just the lens...(?)
