This Nano-X Series Variable ND2-32 Filter from K&F Concept provides a 1 to 5-stop adjustment for motion blur, shallow depth of field in bright conditions, and smooth cinematic video without overexposure. It has a 28-layer nano coating that resists water, oil, and fingerprints. It eliminates ghosting and flare, and delivers ultra-high light transmittance, ultra-low reflectivity, and true-to-life color neutrality. Made of optical glass and CNC-machined aluminum, it has a stepped ring for smooth, precise exposure adjustments. A protective case is included.
