Another interesting article where the author documents how to measure and adjust for camera lens-mount tilt on mirrorless cameras with a rotating lens adapter.

Lenses themselves often also have tilt from 50-200 microns, which you can also measure and shim.

Linked in TFA, with Roger noting he's been "outgeeked", means it's likely excellent reading.

I liked the technical content of both articles, but wow, those are a lot of words to cover their respective content. I get it that it is like long-form journalism, it adds personality and humor, but I also find that (for me) it takes away from the learning. Also, after skimming through the second article, I had to wonder: if the first article found dropped cameras and other problems in flange-to-sensor data, wouldn't they also find mount tilt if they looked for it? Given that drops don't usually impact the camera exactly orthogonal to the plane of the flange, it seems like flange-to-sensor distance won't be their only problem. But maybe replacing the flange on these also fixes any tilt. Then again, there may be damage that affects the tilt but not the flange-to-sensor distance. Someone posted technical illustration of the Denz measuring equipment, and I wonder if they couldn't make a similar apparatus with 3 or 4 pairs of measuring beams (or 2 in a cross pattern), thus it could measure the distance at several points and thus the parallelism of the 2 planes.
