The K&F Concept 55mm KV34 Slim Variable/Fader ND Filter (ND2–ND400) is a versatile exposure control solution for shooting in bright or changing light conditions. With a variable optical density range of 0.3 to 2.6—equivalent to 1 to 8.6 stops of light reduction—this filter evenly darkens the entire image while maintaining natural color balance. It enables wider apertures for shallow depth of field or slower shutter speeds to create smooth motion blur, making it ideal for landscapes, waterfalls, streams, and creative video applications. The blue multi-coated surface helps reduce reflections and glare for clear, high-quality results. Designed with a slim aluminum frame, the filter minimizes the risk of vignetting on wide-angle lenses and allows smooth, precise rotation for easy adjustment. Compatible with lenses featuring a 55mm filter thread, this variable ND filter is a reliable and essential addition to any camera kit.
