I can HIGHLY recommend Kanto camera. They serviced two older Canon LTM lenses for me - including making and fitting a new properly coated element in the 50mm F1.2. Both lenses are now amazing, and the 50mm F1.2 is probably better than when it left the factory. It helps that I am based in Tokyo, so the process was much simpler for me. I have seen some their work repairing and painting M3 bodies - these guys are professionals of the highest order.

Great to hear that you were happy with the work they did!
