The Urth 82mm ND16 lens filter offers a fixed 4-stop light reduction for professional photography and videography applications. This circular neutral density filter allows for precise exposure control in bright lighting conditions and enables photographers to use wider apertures for shallow depth-of-field effects without overexposure. Made from German B270 SCHOTT optical glass, the filter features 20 layers of advanced nano-coating that enhance light transmission while providing protection against water, oil, and scratches. The ultra-slim Magnalium frame design prevents vignetting and maintains image quality across the entire frame. With a double-threaded construction, this filter supports stacking multiple filters and accommodates standard screw-on lens caps. The 4-stop density is particularly effective for long exposure photography, motion blur effects, and cinematic videography, where controlled light reduction is essential. The optical glass preserves color accuracy and image sharpness, while the robust construction ensures reliable performance under various shooting conditions. This filter is compatible with all 82mm threaded lenses and serves as an essential tool for landscape photographers, videographers, and enthusiasts seeking precise exposure control. The advanced coating technology facilitates easy cleaning and maintenance while maintaining consistent light transmission properties. The filter design prioritizes optical performance with minimal impact on image quality, making it suitable for professional applications where color fidelity and sharpness are critical requirements.
