Marumi Digital High Grade filters have been specially designed with Digital Photography in mind. Each filter uses a specially developed ultra-low reflection coating to minimize internal reflection off the cameras built-in CCD and CMOS Sensors. Other anti-reflect features include a special slim frame with satin smooth finish and a black ink process on the glass edge to eliminate flare.\n\nMarumi DHG Super Lens Protection filters incorporate the same features as the Digital High Grade range plus 2 additional benefits:\n\n1. HARD PROTECTION – Guards lens surface from scratches even with heavy duty use.\n\n2. WATER AND OIL REPELLENT – Water and oil spots simply wipe off.
