Hoya 77mm EVO SMC Circular Polarizer Super Multi-Coated Slim Frame Glass Filter Water & Stain Resistant
ThisHoya 77mm EVO SMC Circular Polarizing Filterallows the photographer toremove unwanted reflectionsfrom non-metallic surfaces such as water, glass, etc. Polarizers also enable colors to become more saturated and appear clearer, withbetter contrast. This effect is often used to increase the contrast and saturation in blue skies and white clouds. This circular polarizer from Hoya produces these effects without affecting the overall color balance of the shot.These professional quality filters are made in Japan using precision optical glass that is carefully smelted and blended to yield perfect optical results. Hoya has applied the same care and precision to the multi-coating process, using anImproved Super Multi-coating (IS-HMC)formula togreatly reduceoreliminate reflectionsoff the surface of the glass. In addition, the filter is overlaid with aclear water & stain resistant coatingthat 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.In addition, all Hoya EVO filters have verylow-profile aluminum filter framesto 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 also makes the filterscompatible with a wide array of superandultra wide-angle lenses.Key Features:• Removes unwanted reflections from non-metallic surfaces• Boosts color saturation, clarity and contrast• Does not affect overall color balance• Improved Super Multi-coating (IS-HMC) greatly reduces lens flare and ghosting• Low-profile aluminum filter frame helps avoid vignetting on super wide angle lenses
