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) ?

Could be. Any way to check that without shooting a whole roll on different shutter speeds and logging it?
