I've been shooting it pre-release. Unfortunately, TTA seems to have some issues with the Z mount that I test on that the E mount doesn't have...I like what I see so far when the lens works well, but it for sure has some AF issues that their 75/2 doesn't have, at least on my Z copy.
It has a little bit of that dreamy/bloomed look wide open too, if you enjoy that sort of thing.
