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

I think that this usually means that a person hasn't looked hard enough but not everyone is into pixel peeping .

haha. It might be because I only own two lenses which are both primes and seem super sharp. Maybe I’ve just been lucky, but maybe I just haven’t owned enough lenses 😂

Every lens I have owned (since getting a 70D - my first body with AFMA) has required some adjustment (usually minor). Lenses have been EF 35 f2 IS, EF 24-105L, EF 24-105 L ii, EF 100L f2.8 IS macro, EF 100-400L & EF 100-400L ii.

I don't think I have ever had to go back and redo the AFMA periodically.

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 can't comment on 3rd party AF lenses as I stopped buying them after a poorly performing Sigma 17-50 f2.8. Nearly all of them (3rd party AF lenses) seem to have some sort of issue with some or other Canon body (especially newer DSLRs) - even if it is a non-AF related issue like the Sigma 24-105 chewing batteries faster than a Canon lens. I have one 3rd party lens and that is a Samyang 14mm f2.4 XP (their premium range of lenses) and it is MF.


ah that’s good to know about third party lenses.
