Re: Does Canon 6D MFA work for 35/1.4 ART?

Unfortunately Sigma + Canon DSLR can be problematic.

I had a Sigma 17-50mm f2.8 zoom and tried it on both 600D and 70D. No AFMA on 600D, so I assumed that the 70D would be better - it was .... sort of, sometimes.

I spent many hours trying to fine tune it in using AFMA (on 70D) at both wide & tele, and got it to be generally quite good. But sometimes (erratically) the lens would just mis-focus - often at the wide end and f2.8, but not always.

When it worked, it was a nice sharp lens, but I just couldn't rely on it because it cost me a number of irreplaceable shots, so I gave up on Sigma and have stuck with Canon AF lenses. YMMV.
