NiSi 58mm Pro Nano Natural CPL Circular Polarizer Filter

The NiSi Natural CPL is designed to reduce glare and reflections from non-metallic surfaces, increase saturation and vibrancy in the sky and foliage while ensuring true color reproduction is at its best by eliminating the warming effect that many polarisers create. Our Natural CPL removes the warm tone seen with other brands of CPL filters and provides a closer true color representation of the scene. The Natural CPL features a unique two-tone frame with a silver front ring, black back ring and both are made from high-quality aluminum. NiSi's Natural CPL utilizes Cine seal technology which blackens the edge of the CPL for added durability. This technology reduces the influence of temperature fluctuations and keeps out condensation.

A 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. The light from the sun naturally becomes partially polarized due to reflecting off electrons in air molecules, causing the light to scatter into what appears as haze. 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 reduction of glare and reflections from non-metallic surfaces and an increase in the saturation of skies, foliage, and allows the camera to capture what is under the surface of shallow water.

Our 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. The slimline frame of the NiSi Natural CPL is durable and tough and allows a lens cap to be attached for convenience.
