This sale is for a really excellent condition Mamiya RB67/RZ67 Prism Finder, suitable for use on all RB67 and RZ67 cameras.
This non-metered prism is optically and mechanically in great condition and in perfect working order. The prism has superb glass, connects perfectly to the camera, but has light but obvious rub marks on top of the prism case, probably due to rubbing in a camera bag or something similar. Otherwise there are no issues. Please note that this prism does NOT include the eyecup or bottom cover. The price takes this into account.
