This lens has a much more crisp feel--the SA is very minor, and much less than the 35/40/50 1.2 I've shot. Below are crops from a modded a7--I took a series at 1.5, f2 and 2.8. One with dark subjects, and one with brights that SA shows up on more in my experience a bit.
Then I included 3 actual photos, at different distances, all WO. You'll see there's very very minimal SA.
