NiSi S5 Landscape NC CPL

This NiSi Landscape Circular Polarizer Filter is designed for use with a NiSi S5 150mm filter holder kit. When screwed into a NiSi S5 150mm filter holder kit's 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.

A circular polarizer only differs from a linear polarizer in that it contains a quarter wave plane in addition to the linear polarizing filter. The addition of this quarter wave plane is to circularly polarize the linearly polarized light for the use of auto focus and exposure functions. Due to how the light is broken down and filtered with a linear polarizer, auto focus and exposure accuracy become skewed during use. When the light becomes circularly polarized, it permits the use of these functions.

This landscape circular polarizer filter is designed to provide a saturation effect that is approximately 25% greater than a NiSi Circular Polarizer Filter for NiSi S5 150mm Filter Holder Kits. It is constructed from optical glass for clarity and features an aluminum-alloy filter ring for durability while remaining lightweight.
