I tested SEL 50/1.8 in shop and first sample had a soft corner even at f/4.
Quite interestingis that lens passed local fast test with defocused image well - blur was very symmetric.
Second sample was good.
My 16-50 has small assymetry in defocus image and two corners are slightly softer then other two.
