This sale is for an excellent overall condition Mamiya M645 CdS Prism Finder for manual exposure metering, in perfect working order, suitable for any of the older Mamiya 645 cameras – the M645, M645J or M645 1000S.
This prism has optically perfect, really superb, metering working – just make sure you read the manual (in the Downloads section) before using it. Takes a small LR44 button cell.
It is cosmetically really excellent with just a few paint chips along the top edges, but the hotshoe has come off. If you do not use the hotshoe then this is not an issue (you can still use the flash contacts on your camera body) but it could be glued back on – everything you need is there and the hotshoe is included.
Please note that you cannot use it with any of the newer Mamiya 645 Super, Pro and ProTL cameras.
Instructions for this prism can be downloaded from this website.
