Hoya, a world leader in the production of polarizing filters has set the standard for excellence in the polarizing filter market. Hoya has been producing specialized optical glass since 1941 and they have it down to a fine science.
The purpose of polarizing filters is to filter the light rays that enter your camera lens. This filtering eliminates undesired reflections, increases color saturation and enhances contrast. The result is a clearer, more detailed picture. A Hoya polarizing filter is often used to enhance the contrast between blue skies and white clouds, but the filters do not alter the actual color balance of a photograph.
Hoya polarizing filters are also used to prevent undesired reflections from non-metallic surfaces like water and glass.
Hoya produces two kinds of polarizing filters: linear and circular. Linear Polarizing and Circular Polarizing filters have the same effect. Choosing the correct one will depend upon your camera recommendations.
Hoya polarizing filters are made with a hardened 8-layer waterproof multi-coating that is both scratch and stain resistant. This coating allows an average light transmission rate of greater than 99% on average distance shots. This impressively reduces reflections that bounce off the surface of the glass and enable you to capture greater light in your photographs.
Serious photographers should always carry a Hoya polarizing filter in their camera case. Great for outdoor shots, these polarizing filters are made for most types of cameras, from the medium format to the digital type point-and-shoot. Single lens reflex cameras with Autofocus require the Hoya circular polarizing filter, which allows front-side rotation.
Whatever the light or reflection challenge, the professionals at Hoya have created polarizing filters that can eliminate the problem. Consider making one part of your camera gear.
