• Light rays which are reflected by any surface become polarised and polarising filters are used to select which light rays enter your camera lens. They allow you to remove unwanted reflections from non-metallic surfaces such as water, glass etc. They also saturate colors and increase contrast.
• These professional quality EVO filters are made in Japan using precision opticalglass that is carefully smelted and blended to yield perfect optical results. Hoya has applied the same care and precision to the multi-coating process, usingan Improved Super Multi-coating (IS-HMC) formula to greatly reduce or eliminate reflections off the surface of the glass.
• These coating are over-layed with a clear water & stain resistant coating that is easy to clean. This makes for easier care and handling of the filter in the field. All coating layers are applied in a furnace to bond the coating to the glass.
• All Hoya EVO filters have very low-profile aluminum filter frames to house the glass and keep it perfectly parallel to the plane of the CCD or COS sensor while providing enough rigidity to hold up to years of use. The low-profile frame alsomakes the filters compatible with a wide array of super and ultra wide-angle lenses.
