K&F Concept ND8-ND128 variabel neutral density filter 55mm

The K&F Concept ND8-ND128 Variable Neutral Density Filter is a versatile tool for photographers and videographers seeking precise exposure control. With a stepless adjustment from 3 to 7 stops (ND8-ND128), this filter allows you to achieve creative effects like silky smooth water and motion blur even in bright conditions. Crafted from Japanese AGC optical glass with 28-layer multi-coating, it ensures true color neutrality and eliminates unwanted reflections.

Advantages

This variable ND filter offers exceptional flexibility by combining multiple ND filters in one. The ultra-slim 7.4mm aviation aluminum alloy frame minimizes vignetting on wide-angle lenses. The smooth rotation mechanism enables quick adjustments without color shift, and the X-pattern prevention design eliminates the cross pattern at maximum density. Water-repellent, scratch-resistant, and oil-proof coatings keep the filter clean and durable.
