The KW Revolution Magnetic Circular Polarizer Filter helps to increase saturation while also reducing reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface. An included Kase magnetic lens adapter ring allows the filter to be used on a lens with 58mm front filter threads. Mounted within a nonthreaded filter ring, the KW Revolution Circular Polarizer Filter includes multiple layers of anti-reflection coatings to prevent internal ghosting and reflections while further enhancing clarity as well as color fidelity. These coatings also offer greater protection to the filter substrate and help it to stay clean for longer than with uncoated filters. The KW Revolution line of filters from Kase are color-coded for quick and easy identification and feature front threads allowing them to be compatible with a wide range of filters and accessories.
