This sale is for an excellent condition Beattie Mamiya M645 Matte focusing screen – suitable for the three Mamiya M645 series cameras (M645, M645J and M645 1000S).
This screen is boxed. It has light marking where someone has tried to clean the screen, but this is barely visible in use. There are no scratches and it is otherwise mint. This is the matte only screen, without any focusing aids. Very cheap for one of these rare Beattie screens.
It gives around 2 to 2.5 extra f stops of brightness in the viewfinder compared to a standard Mamiya screen. You can find loads of information about Beattie screens in the Downloads/Miscellaneous section on my website. It will be very securely packed for shipping.
