The True Color Pro Nano Coated Circular Polarizing Filter from NiSi is designed to reduce glare and reflections from non-metallic surfaces and increase saturation and vibrancy in the sky and foliage while ensuring true color reproduction. The proprietary NiSi Pro Nano Coating helps to reduce unwanted reflections and provides a waterproof and scratch-resistant layer to assist in the cleaning of unwanted fingerprints, dust, and water stains. This circular polarizer removes the warm tone seen with other brands of CPL filters and provides a closer true color representation of the scene. It also utilizes Cine seal technology that blackens the edge of the CPL for added durability, to reduce the influence of temperature fluctuations, and to keep out condensation.

This filter is made to fit the NiSi S6 150mm filter holder system. It can be used with an older generation S5 adaptor, but it must be used in combination with the S6 holder frame.
