K&F Concept 67MM KV34 Slim Variable ND Filter ND2ND400

The K&F Concept 67mm KV34 Slim Variable ND Filter (ND2ND400) provides smooth, adjustable light reduction from 1 to 8.6 stops, enabling precise exposure control without color shift. Its blue multi-coated, slim design minimizes vignetting and supports creative shooting with wider apertures and slower shutter speeds.

This filter is designed for photographers and videographers who need flexible exposure control in bright or changing lighting conditions. Featuring a variable optical density range of 0.3 to 2.6 (equivalent to 1 to 8.6 stops of light reduction), it evenly darkens the entire image while preserving natural color balance. It allows 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 work. The blue multi-coated surface reduces reflections and glare, helping maintain image clarity. Its slim aluminum frame minimizes the risk of vignetting on wide-angle lenses and ensures smooth rotation for precise adjustment. Compatible with lenses featuring a 67mm filter thread, this variable ND filter is a reliable and essential addition to any camera kit.
