Okay. My suspect lens is on the A7iii here, my good copy of the same lens is loose. Both are stopped down to f/16, which is clearly not the same between them. I hope this is the problem because that's nice and easy to solve

I don’t think that would cause the banding. Have a look at https://en.wikipedia.org/wiki/Focal-plane_shutter#Two-curtain_shutters

Its possible that there is some timing issue between the two shutter curtains.  Do you get the same issue with shots with openings longer than 1/30s (say) and less than (1/30s) ?
