K&F CONCEPT 43MM, True Color Variable ND2~ND400, ultra-thin adjustable filter, optical glass

The K&F Concept 43mm True Color Variable ND2–ND400 Filter delivers smooth, adjustable light reduction while preserving accurate, neutral color rendition. With premium optical glass, ultra-thin construction, and precise rotational control, this VND filter is ideal for long exposures, wide-aperture shooting, and eliminating the need for multiple fixed ND filters.

Achieve flexible and precise exposure control with the K&F Concept 43mm True Color Variable ND2–ND400 Filter, designed for creators who need versatility in changing lighting conditions. Covering an extensive range from ND2 to ND400, this adjustable neutral density filter allows you to reduce light by 1 to 9 stops, enabling longer shutter speeds, wider apertures, and smooth motion effects even under bright sunlight. Made from high-quality optical glass, the filter maintains true-to-life color without unwanted tinting, staying faithful to the “neutral density” principle—reducing light without altering the scene’s natural tones. By rotating the front element, you can easily fine-tune density levels, replacing the need for multiple individual ND filters. This VND also functions similarly to a polarizing-style mechanism by controlling the amount of light entering the lens through rotational adjustment. Whether capturing flowing water, soft-motion clouds, cinematic video footage, or shallow-depth-of-field portraits outdoors, this ultra-thin, lightweight filter eliminates vignetting while ensuring clean, high-clarity images. Its design makes it an essential tool for photographers and filmmakers who want full exposure flexibility without post-processing replacements.
