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 camera's built-in CCD and CMOS sensors. Other anti-reflect features include a special slim frame with a satin smooth finish and a black ink process on the glass edge to eliminate flare. This neutral density filter reduces light volume, allowing the photographer to use slower shutter speeds under bright conditions, providing more control and creativity. It features a thin mount and ultra-low reflection coating.
