Hoya 77mm Pro ND64 Filter

Neutral density (ND) filters are the most demanded and essential type of photographic filters because of several reasons. For photographers ND filter means precise control of the amount of light passing through the lens for greater creative control over exposure. For video content creators ND filters helps much to set shutter speeds to match the frame-rate while maintaining the depth-of-field of the footage. 

Middle density filters (ND16 - ND200) will help you to add motion blur to the object in the conditions that generally will not allow camera shutter speed to do so.

HOYA offers its own exclusive and wide lineup of ND filters that are branded into PROND series for both photographers and filmmakers. PROND filters adopt HOYA's clear optical glass that is mounted into a lightweight, precisely crafted aluminum frame. The frame has front filter threads so you can attach additional filters or a lens cap.
