This sale is for a superb, near mint condition Mamiya RB67 ProS Prism Finder, suitable for use on all RB67 cameras, and also the RZ67 series if you want to.
This non-metered prism is in great condition and in perfect working order. There are just a few tiny paint chips on the edges, but otherwise this prism is superb with minimal signs of use. Please note that the eyecup is included, but the base cover is missing. The angle of view when using the prism is slightly downwards compared to the newer type L2 prisms – which is really nice is many situations, especially on a tripod.
The instructions can be downloaded from the Downloads section of this web site.
