The True Color Pro Nano 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.

The True Color CPL features a unique two-tone frame with a silver back ring and black front ring, both made from high-quality aluminum. This 77mm slimline frame design is durable and tough and has front threading to allow a lens cap, additional filter, or other accessory to be attached.
