The 2 in 1 Variable ND Filter combines a variable neutral density (ND) filter with a circular polarizing (CPL) filter, providing essential functionality for filmmakers and photographers. This filter allows you to manage exposure in bright conditions while reducing reflections and glare from surfaces like water and glass. With a light reduction range of ND2 to ND32 (1–5 stops), it enables smooth motion blur effects.Designed to prevent vignetting, the filter's self-locking technology ensures consistent performance, even with wide-angle lenses. Constructed from high-definition optical glass with 30 layers of nano coatings, it minimizes flare and ghosting while protecting against water, oil, dust, and scratches. The aircraft-grade aluminum alloy frame features a non-slip texture for easy installation and removal. Filter Type: Circular polarizing + variable ND Thread Sizes: 58mm, 62mm, 82mm Density Range: ND2–ND32 (1–5 stops) Frame Depth: 0.3” / 7.6mm Material: Optical glass, aluminum alloy Includes: Protective case and cleaning cloth
