The Urth 67 mm Variable ND2 400 + 1/4 Black Mist Filter Plus+ is an optical dual-function filter for photographers and videographers who require precise exposure control and subtle diffusion effects. This professional filter combines a variable neutral density filter with a black mist element in one unit, eliminating the need for multiple filter discs and reducing potential image quality loss. The variable ND component offers adjustable light reduction from ND2 (1 stop) to ND400 (approximately 8.6 stops), allowing for creative control over shutter speed and aperture in bright lighting conditions while maintaining optimal image quality. The integrated 1/4 black mist filter creates a gentle diffusion effect that softens highlights, reduces harsh contrasts, and produces subtle halos around bright light sources without significantly affecting overall sharpness. Made from high-quality optical glass, the filter features multi-layer nanocoating technology that minimizes reflections, ghosting, and lens flares while enhancing color accuracy and contrast. The slim aluminum frame measures about 5 mm in thickness, reducing the risk of vignetting with wide-angle lenses, and includes front threads for attaching additional filters or lens caps. With a 67 mm thread diameter, this filter is compatible with a wide range of camera lenses, making it suitable for landscape, portrait, and film photography applications where both exposure control and atmospheric representation are desired. The Urth Variable ND2 400 + 1/4 Black Mist Filter Plus+ offers a practical solution for creatives looking to expand their toolkit with reliable, professional optical accessories.
