The K&F Concept 100×100×2mm Nano-X ND32000 Square Filter is engineered for photographers who demand maximum control over light and exposure in the brightest shooting conditions. Offering a massive 15-stop (4.5) reduction, this ND32000 filter allows ultra-long shutter speeds that transform moving subjects—such as waves, clouds, rivers, and crowds—into smooth, ethereal visual elements. Made from high-quality AGC optical glass, the filter is precisely ground and polished on both sides to maintain exceptional sharpness, even when paired with telephoto lenses. Its advanced 28-layer nano coating dramatically reduces reflections and glare, ensuring high contrast, accurate colors, and clean long-exposure results. The surface is protected with mildew-resistant, waterproof, oil-repellent, and scratchproof layers, allowing easy cleaning and reliable performance in harsh outdoor environments. Designed in a universal 100×100mm square format with a stable 2mm thickness, the ND32000 fits all standard square filter holders and is suitable for lenses up to 82mm in diameter. A premium leather-style pouch with a cushioned sponge interior is included to protect the filter during storage and travel.
