K&F Concept 43MM KV34 Slim Variable ND Filter ND2ND400

The K&F Concept 43mm KV34 Slim Variable ND Filter (ND2ND400) offers smooth, adjustable light reduction from 1 to 8.6 stops, giving you precise control over exposure without color shift. Its blue multi-coated, slim design helps minimize vignetting while enabling creative use of 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), this filter evenly darkens the entire image while preserving natural color balance. It allows wider apertures for shallow depth of field or slower shutter speeds to capture motion blur, making it ideal for landscapes, waterfalls, streams, and creative video. The blue multi-coated surface reduces reflections and glare for clear, high-quality results. Its slim aluminum frame minimizes the risk of vignetting on wide-angle lenses and ensures smooth rotation for precise adjustment. Compatible with lenses that have a 43mm filter thread, this variable ND filter is a compact and reliable tool for creative shooting.
