Haida Greystone CPL Filter Optical Glass MultiCoating Nano Coating Waterproof Scratch Resistant SLR Camera Lens Circular Polarizer Filter77MM

Improved ImageThe CPL filter helps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a nonmetallic surface A polarizing filter arranges and filters 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 nonmetallic surfaces and an increase in the saturation of skies and foliage Ultra Slim To prevent internal ghosting and reflections the glass includes 10 layers of antireflection coating These coatings also offer greater protection to the filter substrate and helps it to stay clean for longer than with uncoated filters Circular PolarizerCircular polarizers are ideal for use with digital cameras and autofocus lenses where a linear polarizer will often disrupt auto exposure and focus features 25x filter factor reduces exposure by 13 stops Optics GlassThis polarising filter is constructed from optical glass for clarity as well as color fidelity and features an aluminumalloy filter ring that can be rotated in order to adjust the intensity of the polarization effect Easy InstallationThe filter ring can be rotated to adjust the intensity of the polarization effectStrongest effect when used at a 90 angle from the sun 77mm front filter threads allow for use with other filtersTop knurling to provide a more textured grip when mounting or removing it from a lens.
