Compare prices :  Hoya 52mm Circular Polarising Filter

Light moves through space in straight lines vibrating as waves in many different directions. Light which is polarized however only vibrates in one plane. A polarizing filter or polarizer is a lens filter which polarizes light along one plane. This can cut non-metallic reflections and enhance contrast under certain conditions.------Polarizing filters contain a layer of polarizing material which is laminated between two glass circles and mounted in a frame. You can then rotate this filter which affects the amount of light passing through. Even at their brightest setting however polarizing filters reduce the amount of light entering the lens - they always cost a stop or so of light.------Polarisers are useful for cutting reflections from water and glass (ie: non-metallic) surfaces. Theyre commonly used for cutting reflective glare off of windows or for taking a photo of a lake without a reflection on the lake surface for instance.------The Circular Polarizer also increases contrast and colour saturation. Recommended for TTL & AF cameras and Video camcorders. less info
