The high-quality Marumi filters were specially developed for digital photography. Each filter is equipped with a specially developed coating that prevents internal reflection of the camera's CCD and CMOS sensors. In addition, a special, thin frame with a satin finish and the BlackInk Process prevent reflections. Marumi DHG Super Circular Polarizing Filters have the same features as the High Grade Filters, with 2 additional benefits:

Hard protection: protects the surface of the lens from scratches, even with very frequent use.
Water and oil repellent: water and oil drops are easy to wipe off.
