The K&F Concept 100×100×2mm Nano-X ND16 Square Filter is engineered for photographers who require precise exposure control and superior optical performance. With a 4-stop (1.2) reduction in light, it allows longer shutter speeds to capture motion effects such as flowing water, moving clouds, and smooth long-exposure visuals without overexposure. Crafted from premium AGC optical glass, the filter undergoes fine grinding and double-sided polishing to maintain exceptional sharpness—even on telephoto lenses—ensuring clean details and high-definition image quality. Its advanced 28-layer nano coating reduces surface reflections, effectively cutting glare and ghosting while enhancing color accuracy. The surface features mold-resistant, waterproof, scratchproof, and oil-repellent protection, allowing you to easily wipe away moisture or smudges during outdoor shooting. Measuring 100×100mm and 2mm thick, this ND16 filter fits standard square holders and supports lenses up to 82mm in diameter. A protective leather-style pouch with soft sponge lining is included to safeguard the filter during travel and storage.
