K&F Concept Variable ND Filter ND3-ND1000 43mm Gray

The K&F Concept Variable Neutral Density Filter is an essential tool for photographers and videographers seeking creative control over exposure. This 43mm filter allows you to smoothly adjust the density from ND3 to ND1000, reducing light by 1.5 to 10 stops. Crafted from high-quality optical glass with multi-layer nano coating, it ensures neutral color balance and protects against water, oil, and scratches. The ultra-slim aviation aluminum alloy frame prevents vignetting, even at maximum density, and features a smooth rotation mechanism with hard stops for precise adjustments. Ideal for long exposure photography and videography, this filter enables wider apertures and slower shutter speeds in bright conditions.

Advantages

Versatile light control with a wide ND range, durable construction, and excellent optical clarity. The multi-layer coating repels water and oil, making it easy to clean. The slim frame avoids vignetting on wide-angle lenses.
