The Cinema 4 x 5.65" True Color Pro Nano Linear 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 linear polarizer removes the warm tone seen with other brands of CPL filters and provides a closer true color representation of the scene. It is made of optical glass and features Cine Seal technology that blackens the edge of the filter for added durability, to reduce the influence of temperature fluctuations, and to keep out condensation.
This filter is compatible with all leading brands of matte boxes that fit the 4 Ã¿ 5.65" standard. The cinema filters also conform to the 4mm thickness allowing them to fit into filter cages or slot into cageless designs
