The Nikon 62mm Circular Polarizing Filter II reduces the amount of light reflected from non-metallic surfaces to preserve image saturation. Its slim design blends with the lens construction. The lens filter allows you to adjust the sharpness of the blue sky and clouds. You can obtain the pure blue color of the sky when taking photos in bright conditions. The filter also makes it possible to photograph objects behind reflective non-metallic surfaces such as water and glass. You get optimum results from the filter by placing it 90° to the sun. A plastic case is provided with the filter for safe storage.
