K&F Concept 58MM Adjustable Black Mist 1/4 & Variable ND2ND400 Filter

The K&F Concept 58mm Adjustable Black Mist 1/4 & Variable ND2ND400 Filter combines cinematic diffusion with precise exposure control, offering a versatile 2-in-1 solution for photographers and videographers seeking dreamy highlights and smooth light adjustment.

This premium 2-in-1 creative tool merges the atmospheric glow and reduced contrast of a Black Mist 1/4 diffusion filter with the flexible exposure management of a variable ND, offering seamless adjustment from ND2 to ND400. The putter-style adjustment system provides precise stop control and smooth 360 rotation, making it especially useful for video shooters who need fine-tuned, real-time exposure changes. Made with imported AGC high-definition optical glass and enhanced with 28 multi-layer nano coatings, the filter delivers exceptional clarity while remaining resistant to water, scratches, oil, and mildew. Thanks to K&F's self-frame lock technology, it eliminates the common X cross pattern seen in typical variable ND filters, even when shooting with wide-angle lenses. This multifunction filter is perfect for cinematic video production, portrait work, landscapes, and any creative shooting scenario requiring both diffusion and variable light control.
