The Marumi 82mm DHG ND2- ND400 Neutral Density Filter allows continuously variable light adjustment through from ND2 to ND400. With one single filter the user can create different densities by rotating the filter in the same way as using a Polarizing Filter. The Neutral density filter reduce light volume, enables the photographer to use lower shutter speeds under very bright sunlight without altering the colour tone of the picture.
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 facilitates to eliminate flare. Japanese optics and original light reducing material is used for construction of this filter. Its super lightweight and extremely thin design makes autofocus more optimum.
