I recently finished adapting this rare lens to the Sony A7R II for general photography. This adaption allows focus from 1:3 to infinity.
Lens details is here: http://www.macrolenses.de/ml_detail.php?ObjektiveNr=78 by Dr. Klaus Schmitt.
After one week of testing, I must say that the sharpness and smooth bokeh of this lens in general, closeup and macro is impressive.
The lens on the AR7R:

In macro mode, I stacked the lens in front of the Gretag 120mm for 2X and test against the well known Minolta scanner lens. The target is the wafer chip from Macro_Cosmos (thanks).
100% crop, Upper is Minolta, Lower is Zeiss.

Corner
From this quick test, I have to say that the Zeiss combo is better both in contrast and resolution.
A quick note from using the wafer. It is very difficult to get the lighting the same when testing lenses. For this test, the camera was set in A with +0.3 for both lenses in room light. Both lenses were flocked with filter on. The outside area of the target was also blacked out to prevent stray light. Any suggestion?
Edit to add:
I finally got my flash to work. Same story, but much better quality.
