I use this lens as well in my A7RII and the focus is slow and sometimes not accurate, mostly if you're not using the central point. And outside the center is less sharp than my manual Canon FD 50 1.4 until f4 or so. You should have better kept the AF 50 1.4 I guess...

The 85 1.8 with the USM focusing system is awesome though.

It's certainly accurate enough, but it is definitely slow, hesitant, and man... That motor noise... Wow.

It's slow, yes, but I would not call it hesitant. The old one was acceptably fast [i]if[/i] it nailed the focus exactly on the first try; if it overshot, which it did in many cases, it would start to grind and whine on and on and on for what seemed like an eternity, causing you to reach for the focus ring, only to curse when you remember that the lens wouldn't allow full-time AF.

At least the STM never does that.
