Mamiya K/L 180mm f/4.5 lens for RB67 There is slight clouding on the internal lens. It should be usable for shooting if it doesn't get worse, but it's listed as junk, assuming it will need repair. The shutter fires crisply at all speeds, even 1 second, without sticking. As another seller mentioned, balsam separation can be fixed for around 10,000 yen, and I believe the clouding is simpler and can be fixed with cleaning, etc.
