Hoya 49mm PRO ND 64 Filter

The PROND64 has a 6-stop light reduction equal to a ND optical density of 1.8.

The ACCU-ND technology in the Hoya PROND filters yields a truly neutral color balance that will not add any noticeable color-cast to your images. The Hoya PROND series is aimed at the still photography and HDSLR video markets. The series provides 10 filters from one stop to 10 stop light reduction.

The Metallic ACCU-ND coating on the PROND filters do not color shift as you move from one density to the next, a common problem with other series of neutral density filters. Now you can set your white balance once and have the same color balance even if you need to change filters due to changes in lighting, or for creative effect.
