The Hoya Pro 1 Digital CPL 52mm Filter Cir PL Circular Polariser has a more specialised coating to cater for the shinier surface of the digital image sensors.

Color and Contrast Enhancement

Light rays which are reflected by any surface can become polarised so the Hoya Pro 1 Digital CPL 52mm Cir PL Circular Polariser is used to select which light rays enter your camera lens. CIRCULAR PL filters allow you to remove unwanted reflections from non-metallic surfaces such as water, glass etc. They also enable 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 polarising filters do not affect the overall color balance of a shot.
