Hi, I'm interested in the Beattie split image screens for converting my F-801 into a nifty manual focus camera. The manufacturer says that their screens are significantly brighter (up to 1.5 stops) than the original screens. This makes me wonder if the metering would be affected. A cross-section illustration of my camera shows that the metering cells are mounted after the screen (ie., light has to travel thru the screen before hitting the cells). Has anyone had any experience with Beattie screens, and if so is exposure compensation required? Thanks, Zig
