Hoya 52mm EVO SMC UV Super Multi-Coated Slim Frame Glass Filter Water & Stain Resistant
ThisHoya 52mm EVO SMC Ultraviolet UV Filteris a multi-purpose filter that is designed to optimize the photography experience of the digital SLR user. UV filtersabsorb ultraviolet raysthat often make outdoor photographs hazy and indistinct, and should be constantly fitted to a lens to provide improved clarity and color balance, as well as toprovide protection to your lens.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:• 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• Improves clarity and color balance• Protects your lens surface from dust and scratches
