Mamiya 7II repair. Needed a rangefinder adjustment, repair to back latch and replacing damaged bottom cover. I am often asked about the difference in the rangefinders between the Mamiya 7 and the 7II. Well, the rangefinders are identical. What is different is that the 7II has a bright frame window on the top cover that has an anti-reflection coating to increase contrast in the frame lines visible in the viewfinder. It has a blue/yellow cast to the glass and some Mamiya 7s have had this upgrade done by Mamiya. But the actual rangefinder is the same. Exception: one very small difference in the rangefinders is the addition of a gold reflector for better frame finder brightness in the Mamiya 7 after production of October 1995. Production of the Mamiya 7 started in June of 1995 so this lack of a gold reflector is not seen in many examples today.
