Does anybody know whether the Leitz polarizer > is a circular polarizer or a linear one? Most current, and for quite some time, Leica polarizers for the SLRs are circular polarizers. There's a very good reason. Any system that uses beam splitters (i.e. all R cameras, and any AF system too, which sends the light through a beam splitter to a secondary mirror) has to work with circular polarizers, because you will get bad meter readings from a linear polarizer. There's a way to avoid the problem manually, but it's not worth the money savings. With M cameras, that's not a problem, since there's no beam splitter. So I suspect they use linear polarizers there, because they are less expensive to manufacture. ========================== Eric Welch Grants Pass Daily Courier
