NiSi Cinema 4" x 5.65" Rotating CPL Filter

The NiSi Cinema 4" x 5.65" Rotating CPL Filter reduces reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface. A polarizing filter arranges, and filters, this directionally polarized light perpendicularly to the reflected light, allowing for the absorption of much of this light. This results in a noticeable increase in the saturation of skies and foliage.

NiSi designed this rotating circular Polarizer with the cinematographer in mind. The filter fits into a standard 4x5.65" mattebox stage and uses a 0.8 gear to turn the circular polarizer inside the filter frame, making it easy to find the desired polarization with the turn of a finger. Its double-sided waterproof coating lets water slide right off, leaving no trace on the filter. Less dust and dirt will stick to the filter, making it easier to clean. The edge of the Polarizer is sealed to keep moisture from entering the filter.
