For Sale: 2 BrightScreen focusing screens for Mamiya C330 (see bright-screen.com). One is MP, microprism style with a 13mm microprism field in the center (good for portraits and waist level finders in general). The other is MPH (micro prism, horizontal),and has a horizontally oriented split prism in the center with a surrounding microprism collar. Both have engravings for exposure compensation exactly like the original screen for the C330. These are much brighter than the original. I’ve used both but recently sold my C330. They are in new condition. They cost me $125 each new. They come with original instruction (takes less than a minute to change screen!). I’d like to sell both for $90. Free shipping CONUS.
