I made some new test shots (it gets a bit dark, but managed). Completely open is a bit hard. Even in the center the result is not razor sharp. The corners do not look much worse than the center. When I stop down to f2.8. everything starts to look really sharp. Maybe my focus was just a bit off. Will try again tomorrow, in daylight.
Will also try the same setup with the NEX-5n, which is in general better behaved in the corners, although I have little experience with this, use mostly retro focus (DSLR) glass.

The center sharpness is very good at f/1.4 according to my results here. The corners aren't bad but nothing to write home about.
