ive tried various large aperture lenses: 3 copies of canon 50 1.4, my current 50 1.2, and a sigma art 35 1.4 and have many other lenses. I have the most problems with autofocus with the large aperture primes. All my other lenses focus far more accurately. And for me it's not a dof problem. Sometimes it will focus consistently one way. Then in other conditions focus a different direction consistently.
I think such lenses seem to be prone to af problems. Especially when dark. And of course ironically that's what I need them for.
My normal procedure now is to do a test shot wherever I go with one of those lenses and do some quick micro adjustments before using the lens.
