This sale is for one pair of near mint condition rear lens and body caps to fit all RB67 (other than the 50mm f4.5) and RZ67 lenses, plus the RB67 ProSD and all RZ67 bodies.
These caps are genuine Mamiya, not an Indian or Chinese clone, and show only minimal signs of use.
Plenty in stock – but just one listing here. If you want a few caps (or other sizes), just ask.
