K&F Concept Nano-X HD Green Multi-Coated Waterproof Circular Polarizer Filter (77mm)

This Nano-X HD Green Multi-Coated Waterproof Circular Polarizer Filter from K& F Concept is a 77mm multi-coated glass circular polarizing filter that helps reduce reflections and glare by filtering out light that has become polarized due to reflection from a nonmetallic surface. The light from the sun 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 directionally polarized light, allowing for the absorption of much of this light. This results in a noticeable reduction of glare and reflections from nonmetallic surfaces and an increase in the saturation of skies and foliage.

This filter is constructed from German Schott B270 optical glass for clarity as well as color fidelity, and it features green multi-coating to prevent internal ghosting and reflections. In addition, each surface features resistance coating to prevent minor abrasions, repel water droplets, and resist smudging from grease and oil. It is made with an aluminum alloy filter ring that can be rotated to adjust the intensity of the polarization effect.
