Further, that a linear polarizer That person is wrong. It has nothing to do with metering or focus. It has to do with beam splitters, which are polarizers. Some metering systems use them, and most AF systems do. So if there are beam splitters (and ALL R Leicas have them) in the meter, the metering will be thrown off. If the camera is AF, it will need circular polarizers. The M Leica bodies don't have beam splitters for metering, so no problem. Focusing is independent. ========== Eric Welch St. Joseph, MO http://www.ponyexpress.net/~ewelch .'Sounds like art,' the instructor says. 'Well, it is art,' I say.
