The Urth ND4 2 Stop Circular Lens Filter Plus is an 82mm camera lens filter designed for professional photography and videography applications. This neutral density filter provides a fixed 2 f-stop light reduction, enabling enhanced control over exposure settings in various lighting conditions. Constructed with industry-leading German B270 SCHOTT optical glass, the filter ensures optimal optical clarity and minimal color distortion. The advanced 20-layer nano-coating technology provides superior protection against water, oil, and scratches while facilitating easier cleaning maintenance. This coating system also delivers higher maximum light transmission and a more consistent transmission curve for accurate light reduction performance. The ultra-slim rim design prevents vignetting issues when used with wide-angle lenses, while the durable magnalium construction offers long-term reliability. The double-threaded design allows for convenient filter stacking capabilities and compatibility with standard screw-mount lens caps. This filter enables photographers to achieve beautiful shallow depth of field effects by allowing wider aperture settings in bright conditions without overexposure. It also facilitates creative long exposure photography by permitting slower shutter speeds for motion blur effects in daylight situations. Videographers can utilize this filter to create cinematic visual effects by controlling depth of field and motion characteristics in various lighting environments. The 82mm diameter makes this filter compatible with lenses featuring corresponding filter thread sizes, providing versatile application across different photographic equipment. The neutral density filtration maintains natural color reproduction while effectively managing light transmission for professional imaging results. This filter represents a practical solution for photographers seeking precise exposure control and creative flexibility in their photographic workflow.
