Most service that I do on the Mamiya 7/7II involve rangefinder adjustments. When a Mamiya 7 comes into the shop for rangefinder adjustment, first step is to check the lens flange flatness and flange to film distance. These are corrected before any adjustments are made using Mamiya factory test equipment. The rangefinder is carefully adjusted for infinity and one meter. Finally, adjustment is made for the rangefinder vertical image.
I also service all the lenses for Mamiya 7/7II and have equipment to adjust and restore them to factory specifications.
