This sale is for a poor condition Mamiya M645 Prism Finder, suitable for any of the older Mamiya 645 cameras – the M645, M645J or M645 1000S.
This prism is mint cosmetically but has chipped glass inside and a big silvering patch across the centre. This is very intrusive but the prism still just about usable. It is pretty horrible but it works – a real bargain if you want a prism for very occasional use. Or for spare parts? Please note that you cannot use it with any of the newer Mamiya 645 Super, Pro and ProTL cameras.
