K&F Concept 52MM Adjustable Black Mist 1/4 & Variable ND2ND400 Filter

The K&F Concept 52mm Adjustable Black Mist 1/4 & Variable ND2ND400 Filter combines cinematic diffusion and flexible light control in a single, high-performance tool ideal for creators seeking dreamy visual effects and smooth exposure adjustment.

This versatile 2-in-1 solution is designed for photographers and filmmakers who want both atmospheric diffusion and precise exposure flexibility. It merges the soft-glow, lowered-contrast style of a Black Mist 1/4 diffusion filter with the adjustable light reduction of a variable ND, offering continuous control from ND2 to ND400. The unique putter-style adjustment system provides accurate stop control, making it easy for video shooters to fine-tune exposure during live recording. Constructed from premium imported AGC optical glass with 28 multi-layer nano coatings, the filter ensures exceptional clarity while resisting scratches, water, oil, and mildew. K&F's self-frame lock technology helps eliminate the common X cross pattern found in conventional variable ND filters, even when used with wide-angle lenses. This reliable, multifunctional filter is ideal for cinematic footage, portrait photography, landscapes, and more.
