Mamiya RB67 RZ67 Genuine Medium Format Bayonet Body Cap
This is a nice bayonet style body cap for the RB67 or the RZ67. Use it while traveling to preserve your lens mount. I always unmount my lenses for travel and cover the exposed areas with caps, it's much safer and extends the life of your camera and lenses.
This one is in clean condition and works perfectly. There are no cracks or breaks in the plastic. The mount shows light wear.
