Leica Universal Top (Linear) Polarizer Glass Filter - for M Lenses

Cat #13356 New 

A hinge allows it to be swung exactly 180° over the viewfinder for composition and setting, and back again over the lens for metering and shooting. The two special adapters (threaded rings) for the filter sizes E 39 and E 46 delivered with the filter enable the use of the majority of the present interchangeable lenses for the LEICA M-models; others for earlier lenses are also available. The new universal polarizing filter replaces the former polarizing filter A42.
