This sale is for one really excellent condition genuine No. 1 80mm Lens Hood for use with any RB67 or RZ67 50mm or 65mm lens, or also with the original version Mamiya 645 45mm f2.8 C lens.
This hood collapses for storage on or off the lens. There are no real signs of use but there is slight surface oxidation. Easy enough to clean off if it bothers you – just a bit of damp kitchen roll will do the job, it just rubs off.
