I have a 70-200 2.8 II IS, which had some focusing inconsistency with my 5d3 in the past (AFMA wouldn't solve it because it was randomly misfocusing).
I've sent them both to Canon and after a month it came back perfectly calibrated, nails focus all the time without need for any AFMA. However, my backup camera (a 100D or SL1) is hopeless with this lens, misses focus a lot of the time. It works well with my other lenses though.
It doesn't really bother me because I rarely use that body especially with that lens. I could send it to Canon for a month to calibrate but not with the lens (which I need for my work). Questions:
1- Can Canon do anything about my 100D calibration without me having to send in the lens as well?
2- If I buy a 5d4, I'm afraid it could have the same issue and I don't want to send it in for a month right after buying it. Since the 70-200 has been serviced and calibrated for my 5d3, will it also work perfectly with the 5d4 (assuming I don't buy a lemon)?
