Eliminates reflections from non-metallic surfaces such as water, glass etc...
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 a stop or so of light.
So what use are they? Well, polarizers are useful for cutting reflections from water and glass (ie: non-metallic) surfaces. They’re 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.
These G series filters offer both amateur and professional photographers HOYA's famous quality at reasonable prices. They have coatings applied to both surfaces to suppress reflection and increase light transmission.
