I've heard different things about the problems when using these screens. Some one mentions metering problems in the "What camera should I buy?" forum. Long ago I think I recall reading something about it afecting the available f-stops. Meaning the f-stops previous available at at a certain ISO/shutter speed would no longer be possible.

Opinions? Has any one installed one on a 40D or D300? I would be interested in the "rule of thirds" grid focusing screen.

I have read a number of posts regarding these, and other split-prism screens. These are what I was used to on my MF 35mm cameras. From the way they operate, I can anticipate that the metering differences would vary somewhat with aperture, as they begin to get quite dark with smaller apertures, yet are somewhat brighter when wide open. This could create a situation where the camera overexposes at smaller apertures and underexposes at wider lens openings. If you use manual focus lenses a lot, it might be worthwhile to get one.
