K&F Concept Variable ND Filter ND8-ND2000 40.5mm

The K&F Concept Variable ND Filter ND8-ND2000 is a high-quality variable neutral density filter designed for photographers and videographers. With a filter thread size of 40.5mm, it offers a light reduction range of 3 to 11 f-stops, allowing for creative control over exposure in bright conditions. Crafted from Japanese AGC optical glass and aviation aluminum alloy, this filter features a 28-layer nano-coating for waterproof, scratch-resistant, oil-proof, and anti-reflection performance.
