NiSi 77mm S+ Ultra Slim Pro MC CPL Filter (Adorama Exclusive)

NiSi S+ Ultra Slim Pro MC CPL 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 a 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.

NiSi S+ CPL filters are constructed from optical glass for increased clarity and feature a 5.0mm thick aluminum-alloy filter ring for durability while remaining lightweight. It minimizes the potential for vignetting and includes corresponding front filter threads for use with other screw-on filters. To prevent internal ghosting and reflections, each glass surface also includes an anti-reflective, nano-coating that results in an improved beading effect when in contact with water for greater cleaning efficiency.
