This sale is for a probably unused, certainly near mint 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. Three available at the time of listing. There is a little surface oxidation on the rubber – purely due to age – but this can easily be rubbed of if you want to.
