Adjusting the focusing lever of the RF with a 2mm hex wrench is well documented. However, when one has multiple lenses, some do not have the same calibration, and they need to be sent off with the camera to be adjusted. This results in loss of camera, trepidation about possible damage in shipping, return of lenses that are not aligned (reported across multiple forums), and cost. Of course, it is ONLY recommended that one do this rather than try to adjust at home. However, if one decides otherwise....
I have multiple newer ASPH lenses that are perfectly aligned, and some older lenses that are not aligned now that the M9 is adjusted for these lenses - an F1 Noctilux, a 75mm Lux, and a 90mm pre-asph. All were backfocusing. I have read that others describe applying a thin layer of copper to the lens cam. Application of a thin layer of black nail polish allowed all my lenses to be perfectly aligned with no cost other than the nail polish. It is completely reversible/removable with no damage to the lens, and I have not had any change in the focusing with use, as there is no significant wearing. I know some will not like this :angry: , but it is a simple solution that worked very well for me. :loco: Thoughts???
