The NiSi S6 PRO CPL for S6 150mm Holder is designed for use with a NiSi S6 150mm filter holder system. When screwed into a NiSi S6 150mm filter holder adapter ring, it can help 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. It is constructed from optical glass for clarity and features an aluminum-alloy filter ring for durability while remaining lightweight.
Please note if using this with an older generation S5 adaptor, the S6 holder frame must be used in combination.
