Neutral density (ND) filters are the most demanded and essential type of photographic filters for several reasons. For photographers, ND filters mean precise control of the amount of light passing through the lens for greater creative control over exposure. For video content creators, ND filters help immensely to set shutter speeds to match the frame-rate while maintaining the depth-of-field of the footage.
The HOYA NDX4 is an excellent ND filter with a great cost-performance and therefore especially recommended for beginners. It features a high-quality ND coating for an even light reduction across the visible light spectrum and a low-profile frame for a reduced chance of vignetting.
The NDX series applies an anti-reflection ND multi-coating to avoid random ghosts and flares. The ND coating technology provides an even light reduction across the visible light spectrum.
NDX filters are equipped with a low-profile aluminum frame for best durability and minimal chance for vignetting. Especially convenient in landscape photography with wide-angle lenses as well as when stacking filters, which can be done thanks to the integrated front-thread in the frame.
