Collimation in a Leica M body is the alignment of the RF optical patch between the stationary and moving components in the viewfinder, and has nothing to do with a lens's RF calibration. Two of my bodies, the M4-2 and M10-R ... both bought used, have had both collimation errors and distance calibration errors which require a service to correct.
I have used the same set of lenses, including the 'Lux 35, on M9, M-P240, M-D262, and M10-M. RF distance calibration is the first thing I check whenever I buy a body or a lens. The RF distance calibration in the body is a separate thing from the RF calibration of the lens, which has to do with the positioning of the RF actuating cam in the lens rather than the calibration of the RF mechanism's moving mirror in the body. None of my lenses have shown any RF calibration errors.
