The Marumi DHG Variable ND Filter cuts the light reaching your sensor by 1-9
stops (ND2 to ND400). Great for slower shutter speeds, creative waterfall shots,
lowering ISO on bright days, and optimizing video shutter speeds.
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 DLSR sensor, as well as a special slim frame with satin smooth finish and a black ink
process on the glass edge to eliminate flare.
