the Mamiya lenses are rated as being just about the sharpest lenses ever made for a 120 camera. The Pentacon lenses, on the other hand, even the CZJ multifoated ones, are adequate at best, and awful at worst(in the case of a lot of the Russian lenses). That’s optical quality. When you look at mechanical quality, you are comparing one of the best examples of Japanese design and engineering, to one the eastern bloc’s best examples of design and engineering.
