... got a chance to take a quick walk this morning with Z7ii and Plena + Zeiss 135/2 apo sonnar ( the earlier version, not the Milvus one which I understand, has a update coating ).
Thank you for the tests.
I too own the "Classic" version of the Apo Sonnar: I like it more.
Those pictures show the oof rendition of both lenses. The Plena wins; the Zeiss can be used on DSLR too, though
However, I would love seeing how even is the sharpness of both lenses across the frame, and how do they compare near minimum focus distance.

Surprisingly, I am not sure what T stop the Zeiss is but on Plena, shutterspeed was consistantly about 1/2 to almost 1 stop faster using A mode and matrix metering. But the exposure is not identical so it is hard to tell.
It's not surprising at all: the Plena has less vignetting and this does influence the automatic exposure with matrix metering.
EDIT:
Just a side comment on coatings.
Both me and an Italian Nikonian fellow own the (early) Made-in-Japan AF-S ED Micro-Nikkor 105/2.8G VR. The coatings (front element & rear element) have different colors ...
We haven't performed a side-by-side test. However, I don't think that same lenses, manufactured in the same plant, and whose elements have slightly different anti-reflective coatings, could exhibit sharpness, or bokeh, differences larger than those ascribable to sample variations.
