Spoiler from upcoming work - zeiss' MTF curves are compensated for field curvature, so in practical use the resolution will be somewhat lower in the corners, though it may not be noticeable if MTF starts high enough.
Distortion in the 85 is very hard to believe, personally. The u/u' format is not the same as "TV" distortion as found by sites like photozone and TV dist is typically exactly 1/2 that of "true distortion", for simpler distortion shapes, so I would expect under 2% for the 85.
