The EVO circular polarizing filter is engineered to work seamlessly with the Cokin EVO Filter-holder system but will fit any lens with 95mm or 105mm thread. The EVO CRPL uses an HRT polarizing film that absorbs only 1 f-stop of light providing faster and more accurate AF than traditional polarizing filters. 

Its effect is controlled by rotating its front ring. Reflections are removed or reduced revealing the natural color and subject behind the reflection. This results in more colorful leaves, bluer skies, and increased clarity. It also works great on windows and water by cutting the reflection and seeing through to your subject. The filter comes with an elegant soft-touch box to carry it safely.
