Hoya PRO ND4 55 mm Neutral Density Filter

The Hoya PRO ND4 55 mm Neutral Density Filter is a high-quality optical filter designed for photographers and videographers who need precise control over exposure. With a 2-stop light reduction, this filter allows for slower shutter speeds and wider apertures even in bright conditions, enabling creative effects such as motion blur and shallow depth of field. The slim aluminum alloy frame minimizes vignetting on wide-angle lenses, while the multi-coated glass ensures excellent color neutrality and reduced reflections.

Advantages
