This sale is for a mint condition Mamiya M645 Split Image focusing screen – suitable for the three Mamiya M645 series cameras (M645, M645J and M645 1000S). This is the screen with just the split image focusing aid and no microprism for M645 cameras. It cannot be used with the 645 Super / Pro / ProTL cameras.
This screen is unmarked; a superb screen. This is the diagonal split image screen without the microprism. Personally, my preferred screen..
