Stock Code: 66-1071057 Helps to Eliminate Reflections and Glare Reduces Haze and Blue Cast in Landscapes Greater Color and Tonal Saturation High Efficiency Kaesemann Foils Rugged Brass Filter Ring High Quality Schott Glass The B+W 105mm Kaesemann Circular Polarizer 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 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. Kaesemann-type filters feature greater optical efficiency than regular polarizing foils and are more neutral in color. The polarizing foils are cemented between plano-parallel optical glass layers, which are then precision-polished to achieve the most accurate plano-parallel surface. This edge sealing protects the filter layers from humidity and are ideal for use with high-speed telephoto and apochromatic lenses. B+W filters are constructed from high quality Schott glass for increased optical clarity and color fidelity. They feature a brass filter ring for durability as well as jamming prevention. Helps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface. Polarizing filters arrange, and filter, directionally polarized light perpendicularly to the reflected light, allowing for the absorption of much of the light. Clears up haze in distant landscapes and provides more saturated, vivid colors. Strongest effect when used at a 90° from the sun. Circular polarizers are ideal for use with digital cameras and autofocus lenses where a linear polarizer will often disrupt auto exposure and focus features. Kaesemann polarizing foils provide highly neutral coloring and higher image quality than conventional polarizing foils. Constructed from high quality Schott glass for optical clarity. Brass filter ring helps to prevent jamming and provides additional strength. Feedback is very important to us. We would appreciate if you would leave it for us once you have received your item.
