That's not quite accurate I think (on the Nikon front) because:
"That was what many people thought, including me. However, what this teardown shows is the thickness of the removable glass. There is also a glass layer epoxied to the sensor itself, which adds to the total thickness. If the real, total, sensor glass thickness actually was 1.1mm, then even "difficult" M mount lenses would perform flawlessly on a stock Nikon Z camera. Unfortunately, that isn't the case."

That's From LarsHP who is quite active on FM as well. I have a NKIR modded A7r2 with a v3+ version, which has a thickness of 0.75mm. Their WB issue is far less severe than Kolari, otherwise I would have went Kolari UT mod. They were working on a V5 a while ago, which would would result in .58mm. I am curious about that as it might make even Contax G lenses better.
This really gets back at that, I wish someone (not me), would do some legit testing of BSI Z bodies versus a native Leica or UT Mod which is a known quantity at this point....Show more →
I just came across this info from Diglloyd commenting on the Nikon Z sensor stack:
From Kolarivision PANASONIC S1R DISASSEMBLY AND TEARDOWN:
These layers of sensor cover glass (Panasonic S1R) have a combined thickness of roughly 1.45 millimeters. This is thinner than the EOS R, but a decent sight thicker than the Z7’s 1.1mm [diglloyd: actual total thickness is 2.3mm], the thinnest we’ve come across yet. This makes the S1R a poor candidate for legacy Leica lens performance despite the partnership with Leica, meaning this camera is another excellent candidate for our Ultra-Thin filter modification service.
The Panasonic S1R at 1.45mm thick (is this the total thickness?!) is far thinner than Sony mirrorless at ~3mm thick. Hence the horrible performance of M-mount lenses on Sony cameras and the slightly better performance on the Nikon Z7. Judging by my testing, I’m skeptical that the total glass thickness on the Panasonic S1R is only 1.45mm. Even if accurate, that’s a lot thicker than the optimal of 0.8mm thickness.

We haven’t tested the SL2 yet so I can’t comment.
The numbers we report on the sensor glass is only the removable UVIR cut layers, and excludes the permanent clear cover window in the sensor itself. This layer is typically 0.8-1mm but is hard to measure non destructively.
That would make the Panasonic S1R around 2.4mm and the Nikon Z7 around 2.1mm.
