Light rays which are reflected by any surface can become polarized, so polarizing filters are used to select which light rays enter your camera lens. The Hoya 58 mm NXT Circular Polarizer Slim Glass Filter allows you to remove unwanted reflections from non-metallic surfaces such as water, glass, etc. It also enables colors to become more saturated and appear clearer with better contrast. This effect is often used to increase the contrast and saturation in blue skies and white clouds. Hoya's polarizing filters do not affect the overall color balance of a shot.
This popular filter is renowned for their ability to minimize reflection at the filter surfaces which reduces flare and ghosting. The result is an average light transmission of over 97%, giving sharp contrast and well-balanced color. Hoya HMC filters are recommended for enhancing the performance of today's multicoated lenses.
