The partial silver reflector that directs the exposure light to the photocell within the R cameras acts like a polarizer. Pitting a linear polarizer on your lens will block most, if not all of the light from getting to the cell, thus giving you an improper reading. All Leica R cameras REQUIRE a circular polarizer. That's why Leica makes them. Some autofocus systems require a circ polarizer, some don't.
