The K&F Concept 100×100×2mm Nano-X ND2000 Square Filter is designed for photographers who require maximum exposure control during bright daylight or for creative long-exposure effects. Offering an impressive 11-stop (3.3) light reduction, this ND2000 filter allows extremely long shutter speeds to capture silky-smooth water, dynamic cloud trails, and motion-blur artistry even under intense sunlight. Constructed with high-quality AGC optical glass, the filter is precisely ground and polished on both sides to maintain exceptional sharpness across all focal lengths, including telephoto lenses. Its advanced 28-layer nano coating minimizes reflections, enhances contrast, and significantly reduces glare and ghosting, ensuring clean, high-fidelity imaging. The surface features protective coatings that make it waterproof, oil-repellent, scratchproof, and mold-resistant, allowing quick and effortless cleaning in outdoor shooting conditions. With its 100×100mm format and 2mm thickness, the ND2000 filter fits standard square filter holders and supports lenses up to 82mm in diameter. A premium leather-style pouch with a soft sponge lining is included for safe storage and transport.
