Yes Bastian. We hear you.
I would very much doubt that the lens performs equally on a stock Z7 as it does on the M-240 as my understanding is the sensor stack thickness of the Z7 is about 2.3mm, not 1.1mm as reported by Kolari Vision (that figure did not include the total sensor stack thickness). So, unless you are using the lens stopped down to about f5.6 or smaller, I would not expect the lens to perform as well as an M-body. If like an Ultra Thin sensor stack thickness of around 1.1mm of a Z7 or a Sony body (as an example my Kolari Vision UT sensor modified A7rII) then the lens should perform close to an M body. This was confirmed by Fred when he had compared his Kolari Vision UT sensor modified A7rII that he has since sold with his M10R.
