This sale is for an excellent / excellent + condition Mamiya 645 Super AE Prism Finder N, fully tested and in perfect working order. It is suitable for use with the newer Mamiya 645 Super, Pro and ProTL cameras and will not fit the earlier M645 models.
This prism is in great condition. It has only normal very minor signs of use, just typical light scuffs on the case but is otherwise near enough perfect. It is in perfect working order and comes complete with the eyecup.
Instructions for this prism can be downloaded from this website. This AE prism is functionally identical to the later 645 Pro AE prism FE401 – just in a different shaped case.
