K&F 49MM Nano-X Variable/Fader ND Filter, ND32~ND521, W/O Black Cross

The K&F Concept 49MM Nano-X Variable ND Filter (ND32–ND512) delivers smooth light reduction for long exposures and motion blur without color shift. Featuring advanced no–X-cross technology, premium optical glass, and 28 multi-layer nano coatings, it ensures sharp, high-quality images with zero vignetting in a slim, durable frame.

The K&F Concept 49MM Nano-X Variable ND Filter ND32–ND512 is designed for photographers and filmmakers who need flexible exposure control in changing lighting conditions. This variable neutral density filter reduces the amount of light entering the lens while maintaining accurate color rendition—perfect for long exposure photography, silky water effects, motion blur, and video shooting. Equipped with peak no-X-cross technology, the filter eliminates the common “X” pattern seen in other variable ND filters, ensuring clean, artifact-free images. Its premium optical glass maintains edge-to-edge image sharpness and minimizes glare, while the 28-layer nano coating provides hydrophobic, scratch-resistant, oil-resistant protection for superior durability and ease of cleaning. The ultra-slim 7.6mm aircraft-grade aluminum frame is precision-engineered to prevent vignetting, even on wide-angle lenses. With smooth rotation and built-in endpoint stops at ND32 and ND512, this filter offers controlled, reliable performance for both still photography and video production.
