Obviously this lens is very much worth some TLC. You could get a CLA at the same time ;-) Focus shift is certainly a characteristic that you need to take into account in use but that doesn't invalidate correct adjustment. If you do have your M9 adjusted at the same time they can compare where each component lies within its tolerances in case it is possible to tweak either for absolute best compatibility. Within tolerance is within tolerance of course and every properly adjusted body should work properly with every properly adjusted lens. Nevertheless I know that the Solms people can and do make extra efforts to refine adjustments further. In the immortal words of the Solms technician who checked my 50 and 75 with my M8 upgrade "Your lenses are good! We can make them better" I have no personal experience with NJ but you can of course deal directly with Solms if you choose.
