DHG (Digital High Grade) Lens Protect Filters are colourless. They protect the lens and reduce reflections - they do not alter the image. They have a thinner frame than other filters, to prevent vignetting when used with wide angle digital lenses. The frame has a satin smooth finish and the edge of the glass is coated black to futher reduce lens flare and reflections. Made by Marumi.
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.
