My copy of 24-70 f/2.8 II needs -9 at wide end and 0 at tele end on my 5D III. My Canon 70-200 f/2.8 II needs 0 at either end, and my 100L also needs 0. Some of my fast primes including 35L, 50L, 85L II range between -1 and -3.
A brand new Canon 17-40 f/4L I just borrowed needed -6 at wide and 0 at tele.
-9 seems a tad too much for a $2100 lens, so I'm just wondering what 24-70 f/2.8 II owners have experienced with AFMA (and 5D III)? Is it worth sending in the lens to Canon while still under warranty for calibration?
Is my copy of 5D III partly at fault here, as the body seems to need Minus AFMA on lenses, never positive. The body is out of warranty, but should I send in both the 24-70 II and body to Canon for calibration together (does Canon even calibrate a specific lens+body combo?).
Any help would be appreciated.
