Hoya 52mm NXT Circular Polarizer Filter + TheImagingWorld MicroFiber Cloth 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. - Non-coated. Circular polarizers are ideal for use with digital cameras and autofocus lenses where a linear polarizer will often disrupt auto exposure and focus features. Strongest effect when used at a 90 angle from the sun. - Over 97% average light transmission. - Constructed from heat-resistant, high-transparency optical glass.
