This sale is for a used but really excellent condition genuine Mamiya 77mm lens hood for use with the RB67 or RZ67 90mm and 110mm focal length lenses.
This hood collapses for storage on or off the lens and has only very minor signs of use. This is the earlier type hood originally released for the RB67 and much easier to fold back than the later more rigid RZ67 (“No. 1”) version of this hood. Also cheaper!
