The K&F Concept 49mm Nano-X Magnetic Variable ND2-32 Filter is a high-performance, professional-grade neutral density filter designed for photographers and videographers seeking precise light control and hassle-free use. Its magnetic design allows the filter to attach to the lens in just 1 second, dramatically faster than traditional threaded filters. The package includes a magnetic adapter ring for easy installation and removal.

Constructed with premium Japanese AGC optical glass, this filter ensures high-definition image quality without color cast. The self-locking frame technology eliminates the common “X” cross effect often seen in variable ND filters on wide-angle or telephoto lenses.
