So the size of the sensor stack can cause high variation in the results
from a lens, but Canon and Nikon both have wild differences in stack
size between cameras designed to use the same lenses? I’m not sure what
conclusion to draw from that, but it’s weird.

I think most of us don't notice this stuff since it requires a very
short exit pupil distance for anything seriously bad to show up. That
may well be the case with RF lenses and especially short focus RF lenses
but note that the Canon 17/4 has a 90.4mm exit pupil distance... much,
much greater than the focal length of the lens.

Something I have never thought about--seems to matter quite a bit for
fast RF lenses.
MFT has quite a thick stack--wonder what that does to some OMZ lens use.

Nice to see that Oly and Panny are coordinated in stack thickness, so
the lenses are truly interchangeable.
As the only non µ4/3 lenses I've seriously considered using are 600 and
1000 mm, it shouldn't be a problem.
Might be interesting to see how the deep stack affects 'drawing' for
fast lenses for those interested more in lens character than MFT
numbers. Finding a lens with some of the soft/detailed character of old
LF lenses would be pretty nice. :-)
