B + W 72mm Top Linear Polarizer Multi Coated Glass Filter

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 linear polarizer only differs from a circular polarizer in that it does not contain a quarter wave plane that enables use of auto focus and exposure features. Linear polarizers are best suited for use with manual cameras such as view cameras that are not dependent on internal mechanisms to determine focus or metering settings. The Multi-Resistant Coating (MRC) is both an anti-reflection coating as well as a protective surface. It helps to increase light transmission by reducing reflections scattered light and ghosting. Additionally it offers greater protection to the filter substrate and stays cleaner for longer than uncoated filters.
