K&F Concept Nano-X Variable ND2-ND400 77mm
K&F Concept Nano-X Variable ND2-ND400 is a 77mm variable neutral density filter for fixed-lens or threaded-lens use. It gives a wide density range for controlling shutter speed and aperture in bright light, making it useful for video, long exposures and shallow-depth-of-field stills. Nano-X filters are known for slim metal frames and multi-layer coatings designed to reduce flare and maintain usable contrast, while variable ND construction offers quicker adjustment than swapping multiple fixed-strength filters. As with any variable ND, the strongest settings can produce cross-pattern artefacts on some lenses and focal lengths, so it is best used within the practical range for the shot. On the used market, check the glass carefully for scratches, coating wear, dust, haze and cleaning marks, and make sure the front and rear threads are not cross-threaded or dented. Also confirm the rotation is smooth and even across the full range, with no stiffness or play in the ring, and that the filter has its original protective case if possible.
