Filter ND 77mm Hoya ND32 PRO- HOYA PRO ND filters reduce the amount of light entering the lens. Allowing you to shoot in bright light on an open aperture and use slower shutter speeds to achieve a dynamic effect. In order to meet the high level of demands of photography enthusiasts and professionals, neutral filters of the Hoya PRO ND line are manufactured using new technology. Light attenuation is ensured by Metallic ACCU-ND proprietary coating sprayed onto high-quality optical glass. It provides uniform dimming and does not give stray shades in the pictures. Due to this, the photographer will not have to spend time on color correction, and setting the white balance will give an identical result in pictures taken with and without a filter.
