Rangefinder roller has to be *centered* to work correctly with 40 Summicron-C or ELmar-C. They have sloping cams, requiring the rollers to be precisely centered. Other SM and M lenses have flat cams that move back and forth as the lens group moves (50mm) or uses a differential helix to correct the actual lens group movement (smaller for focal length ,50mm, greater for FL >50mm) for other lenses. THis helix is expensive to manufacture, the C lens were made less expensively.
