K&F CONCEPT 58MM ND2-ND400 Variable Filter (1-9 Stop), 24 Layers of Nano-coating

The K&F Concept 58mm ND2–ND400 Variable ND Filter provides adjustable 1–9 stop light reduction for long-exposure and motion-blur photography. Built with HD AGC optical glass and enhanced with 24-layer nano-coating, it delivers superior clarity, minimized reflections, and a durable ultra-slim frame for wide-angle shooting.

The K&F Concept 58mm ND2–ND400 Variable Neutral Density Filter offers flexible exposure control for photographers and videographers working in dynamic lighting environments. With its wide 1–9 stop range, this filter is perfect for achieving smooth long-exposure effects such as silky waterfalls, blurred clouds, and balanced bright-light video footage without overexposure.

Constructed from premium HD AGC optical glass, the filter features 24 layers of nano-coating that reduce reflections, enhance light transmission, and provide exceptional resistance to scratches, dust, water, and oil. The ultra-slim 7.4mm aluminum alloy frame is designed to minimize vignetting, making it ideal for wide-angle lenses. A CNC-machined trapezoidal grip surface ensures smooth and precise rotation for easier control over density levels.

In rare cases, a dark “X” pattern may appear when using extremely wide angles or maximum ND values—this is a normal optical phenomenon with variable ND filters and resolves naturally with continued rotation. Compatible with all 58mm thread lenses, this filter is a versatile tool for landscape photographers, travel shooters, and filmmakers.
