The Hoya ND 64 reduces light by an equivalent of 6 stops.

Neutral density filters (ND filters) are among the most sought-after and important types of photographic filters for several reasons. For photographers, ND filters mean precise control over the amount of light that enters the lens, allowing for greater creative control over exposure. For content creators, ND filters are very helpful in adjusting shutter speeds to match frame rates while maintaining the depth of field of the footage.

Hoya offers an exclusive and extensive range of ND filters embedded in the PROND series for both photographers and filmmakers. PROND filters utilize Hoya's clear optical glass, which is mounted in a lightweight, precisely crafted aluminum frame. The frame features a front filter thread, allowing you to attach additional filters or a lens cap.

Thanks to the leading ACCU-ND technology, the image experiences no negative effects from color shifts that can occur due to inferior materials, poor quality control during manufacturing, or issues with infrared leakage in the light spectrum. This last issue is currently the most significant in photography and videography. With Hoya's exclusive ACCU-ND technology, a uniform reduction of light in the visible and IR spectrum is achieved. As a result, photographers need not worry about color shifts when using Hoya ND filters under various shooting conditions.
