The ACCU-ND technology in Hoya PROND filters delivers truly neutral color that will not add any noticeable tint to your images. The Hoya PROND series targets both the photographic and HDSLR market. The series provides 9 filters, ranging from two stops to 10 stops of light reduction. The metallic ACCU-ND coating on PROND filters prevents color shift when switching from one density to another, a common problem in other neutral density filter series. Now you can set your white balance once and have the same color balance, even if you need to change filters due to lighting changes or for creative action.

PROND filters exclusively use Hoya optical glass that has a metallic ACCU-ND coating to create the neutral density effect.

Neutral filters are designed to reduce the amount of light entering your camera lens and should have no other effect on the image. Reducing the amount of light allows the use of larger apertures or slower shutter speeds for creative and dramatic effects in bright lighting conditions.

The PROND32 provides 5 stops of light reduction equivalent to 1.2 optical density ND.
