Lens calibration Q

Can a L-series lens be calibrated to different bodies, e.g if you own two bodies can you have the same lens calibrated to the two bodies? I was under the impression that a lens can only be calibrated to one body at a time.

EOS 5D MK3 - 24-70 MK2

IIRC the adjustments are stored in the body so I can't imagine why you wouldn't be able to, assuming the bodies have microadjust. (external link)"Vacuous images for the Vapid consumer"

^ Yes this is correct - you can adjust different amounts for each lens on each body, as both the camera bodies and the lenses have individual fluctuations. For example, you may need to be +X on one body and -Y on another... However, I don't think you can send a lens off for calibration to two bodies, but I might be wrong.

Canon (or whichever manufacturer) calibrate a lens to the body if you send both off, OR they calibrate the lens to one of their own bodies that ensures the lens is within acceptable tolerances (if you don't send a body with the lens).

That's my understanding anyway, but someone else may know more :)

Lens calibration is just that and it entails sending the lens and body to a Canon centre (or an approved one)

AF micro adjust is an "adjustment" (you do this yourself) where an offset value is stored in the camera's memory.....each body can be independantly optimised for the lens.

You can buy a software called FoCal. Get the Pro level, or the most expensive version. This version will make the micro adjustments to your camera automatically. The program will also tell you the optimum lens zoom value, called sweet spot. I have bought and used FoCal on my 50D and Canon lenses and Tamron lenses, it has improved the AF with every lens in my bag, including my "L" glass.
