Haida 72mm NanoPro MC Circular Polarizer Filter #HD3291-72

The NanoPro MC Circular Polarizer Filter from Haida 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 and foliage. To prevent internal ghosting and reflections, each glass surface includes 10 layers of antireflection coatings which offer protection for the filter itself.

An anti-static coating has been applied to the surface of the filter, too, to provide easy removal of dust and dirt, which furthermore offers resistance against water and oil to aid in cleaning and removal of water drops and fingerprints.

The thin filter ring design is ideally suited for use with wide-angle lenses and features multiple light-blocking ridges, a satin finish, and a black ink coating to help further reduce the likelihood of surface reflections that can cause lens flare and ghosting
