Haida Drop-In Circular Polarizer Filter for Haida M10 Filter Holder

This Haida Drop-In Circular Polarizer Filter helps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface. Mounted within a geared filter ring assembly, it is made specifically to fit between a separately available Haida M10 Filter Holder and an adapter ring for the filter holder. The geared filter ring assembly's external dial allows for the independent rotation of the circular polarizer filter in order to adjust the intensity of its effect.
