Hoya 58mm DMC PRO1 Digital Multi-Coated UV (Ultra Violet) Filter.

Hoya DMC PRO1 Digital Filters are specifically designed and engineered for Digital SLR Cameras. Digital Multi Coated (DMC) construction greatly reduces lens flare and ghosting. The Black Almite Frame (BAF) is a black matte finish aluminum frame that reduces reflections to enhance contrast. In addition, the Black Rimmed Glass (BRG) reduces light reflection around the filter edge. Low Profile Frame (LPF) is an Ultra thin frame which helps avoid vignetting on wide-angle lenses. The Knurled Edge Frame (KEF) aids easy attachment and removal. UV filter absorbs invisible ultraviolet rays which make outoor photographs hazy and indistinct and serves as a permanent lens protector.
