I've given mine a good going over and have some preliminary conclusions.
Sharp wide open, improves to the sweet spot of F4 to F5.6, diffraction quite noticeable at F8.
Very good but not perfect resistance to flare and CA
Quite low colour shading effects
Nice bokeh, generally round looking but in at least one shot, pentagonal. Go figure.
Just over medium contrast.
Mine is (grrrrr) decentered. The third Sony Zeiss lens in a row where the first copy I had should not have passed QC IMHO.
Here's a growing gallery with Lens Cast shots (with and without corrections on) and flare and bokeh and CA examples, and some focus shift tests that imply there is indeed a tendency for the field of focus to move backwards but for the subject to remain in good focus as you stop down. There are also near and far aperture series, best from bracketed.
The camera totally missed focus with this lens in good light a small number of times, not something I was seeing with the 35mm F2.8..
