Description
NiSi Landscape Circular Polarizer Filter isdesigned for use with a NiSi S5 150mm filter holder kit. When screwed into aNiSi S5 150mm filter holder kit's filter holder adapter ring, it can help toreduce reflections and glare by filtering out light that has become polarizeddue to reflection from a non-metallic surface. The light from the sun naturallybecomes partially polarized due to reflecting off electrons in air molecules,causing the light to scatter into what appears as haze. A polarizing filterarranges, and filters, this directionally polarized light perpendicularly tothe reflected light, allowing for the absorption of much of this light. Thisresults in a noticeable reduction of glare and reflections from non-metallicsurfaces and an increase in the saturation of skies and foliage.
A circular polarizer only differs from alinear polarizer in that it contains a quarter wave plane in addition to thelinear polarizing filter. The addition of this quarter wave plane is tocircularly polarize the linearly polarized light for the use of auto focus andexposure functions. Due to how the light is broken down and filtered with alinear polarizer, auto focus and exposure accuracy become skewed during use.When the light becomes circularly polarized, it permits the use of thesefunctions.
Features：
●This landscape circular polarizer filteris designed to provide a saturation effect that is approximately 25% greaterthan a NiSi Circular Polarizer Filter for NiSi S5 150mm Filter Holder Kits. Itis constructed from optical glass for clarity and features an aluminum-alloyfilter ring for durability while remaining lightweight.
