Seems to be the AF variant of the manual focus 12mm f/2
Odd MTF curve - especially for a lens targeting Astro. It seems to have quite some astigmatism at the corners.
I think the MTF is just a bit more realistic than the Sony MTFs, and the astigmatism probably is pretty good. I thought coma actually is the big fiend of astro?
Coma and astigmatism are very reasonable, according to LensTip:
