Which lenses did you try? Do they show strong distortion, requiring in-software correction? You got any lens with a nice long exit pupil? Could the semi- transparent mirror in the adapter be playing tricks?
Just a few ideas to check for. I assume you went and searched for available full scale samples available from other sides. If the effect is as strong as I understand from you post, one should see that in real world stuff.

So far - the Zeiss ZA 85mm and Sony E 30mm. The Zeiss is "Ok" although with worse borders compared to the initial test. The E lens is sharper in the center but the borders are soft. I haven't analysed the data from the E 18-55 and A 16-50 yet but subjectively (based on the viewfinder feedback) I'm not expecting wonders in the border region either.
