The B+W 55mm Circular Polarizer Slim Filter is highly effective in filtering out the light that causes reflections and glare, the light that has become polarized due to reflection from non metallic surfaces. The sunlight creates haze due to the partially polarized electron in air molecules, causing the light to scatter away while the polarized filter manages to filter the directionally polarized light in perpendicular to the light reflected, absorbing the most part of light. That arrangement helps in considerable reduction of glare and reflection from non-metallic surfaces; it increases the saturation of the foliage and skies.
B+W are the name of quality and are highly recognized by the professionals for its quality products. The filters made by B+W are manufactured with the scotch glass specially arranged in a formation to give you professional celerity in object capturing and color fidelity. The brass ring is durable and easy to use for longer time, slim filters perfectly suitable for using with wide angle lenses, the front threads are missed out to avoid front stacking of additional filters.
The filter is circular polarized containing quarter wave plane, an advantage over the linear polarized filters. It helps in auto focusing with high level of exposure accuracy that becomes tilted during use. The circular polarized light is filtered out for better results on image quality while outdoor shootings.
