The Urth 55 mm ND4 (2 Stops) Lens Filter Plus+ is a professional circular neutral density filter for photographers and videographers. This filter provides a fixed light reduction of 2 stops, allowing for better exposure control in bright conditions and supporting creative techniques such as long exposures and depth of field effects. Made from high-quality German B270 SCHOTT optical glass, the filter features an advanced 20-layer nano-coating that ensures uniform light transmission and protection against water, oil, and scratches. The ultra-thin edge design prevents vignetting with wide-angle lenses, and the robust magnalium construction guarantees long-term reliability. With double-threaded mounting, this filter supports stacking with other filters or standard screw-on lens caps. The 55 mm thread size makes it compatible with a variety of camera lenses, providing photographers and videographers with enhanced creative control over exposure settings without compromising quality. The filter is particularly useful for achieving cinematic motion blur effects, controlling exposure in bright light, and maintaining optimal aperture values for depth of field regulation. The advanced coating technology ensures minimal color cast and maximum accuracy of light transmission, making it suitable for both photography and video applications where precise exposure control is crucial.
