The Urth 46mm ND4 (2 Stops) Lens Filter Plus+ is a circular neutral density filter designed for photographers and videographers who require precise light control. This filter provides a fixed light reduction of 2 stops, allowing for improved exposure settings for long exposures and depth of field techniques, especially in challenging lighting conditions. Made from German B270 SCHOTT optical glass, the filter ensures exceptional clarity and accurate color reproduction. The application of 20 layers of advanced nanocoating maximizes light transmission while maintaining a consistent transmission curve for reliable light reduction performance. This sophisticated coating system effectively minimizes reflections, lens flares, and ghosting, resulting in enhanced image contrast and quality. The rounded design is optimized for wide-angle lenses and significantly reduces the risk of vignetting when used with various lens configurations. The ultra-thin edge construction further prevents vignetting issues, while the robust magnalium frame offers durable protection. The double-threaded design allows for convenient filter stacking and secure attachment of screw-in lens caps, increasing operational versatility. This filter enables creative control by allowing the use of wider apertures in bright conditions for shallow depth of field effects and supports cinematic motion blur techniques through controlled shutter speed adjustments. The protective coating resists water, oil, and scratches, making maintenance and cleaning straightforward. With its precise 46mm thread diameter and professional construction, this filter delivers reliable performance for photographic and cinematic applications that require controlled light reduction.
