The K&F Concept 77mm KV34 Slim Variable ND Filter (ND2ND400) provides smooth, adjustable light reduction from 1 to 8.6 stops, offering precise control over exposure without color shift. Its blue multi-coated, slim design minimizes vignetting and allows creative use of wider apertures and slower shutter speeds.

The K&F Concept 77mm KV34 Slim Variable/Fader ND Filter (ND2ND400) is designed for photographers and videographers who require versatile exposure control in bright or dynamic lighting 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 for smooth motion blur, making it ideal for landscapes, waterfalls, streams, and cinematic video. The blue multi-coated surface minimizes glare and reflections, ensuring clear, high-quality images. The slim aluminum frame reduces the risk of vignetting on wide-angle lenses and provides smooth rotation for precise adjustment. Compatible with lenses featuring a 77mm filter thread, this variable ND filter is a reliable and essential tool for creative photography and video production.
