I've never had to micro focus adjust/calibrate any of my lenses for my canon bodies so far.

I'm looking into getting a general purpose used third party lens for my 5D4 & 6D.

Eg. Tamron/Sigma 24-70, 24-105 etc.

Do third party lenses usually need AF adjustments? I've only ever had native canon lenses.


I found improvements in both Canon and third party lenses. Probably time to recalibrate and see if there was any drift.

Based on my aging memory without digging through the cal files of FoCal I remember more adjustment generally with third party lenses but, as I said, all benefited. Wide angle less so than tele-zooms
