K&F Concept Nano-X Series Variable ND Filter 55mm ND2-ND2000 (1-11 Stops) - Gray

The K&F Concept Nano-X Series Variable Neutral Density Filter is a premium photographic accessory designed for photographers and videographers who demand precise control over exposure and depth of field. With a filter diameter of 55mm, this variable ND filter offers a density range from ND2 to ND2000, equivalent to 1 to 11 stops of light reduction. It is ideal for achieving long exposure effects, smooth motion blur, and cinematic video production in bright conditions.

Advantages

This filter provides seamless adjustment of light intensity without the need to carry multiple fixed ND filters. The Nano-X multi-coating ensures excellent light transmission, minimal color shift, and protection against scratches, water, and oil. The ultra-slim aviation aluminum alloy frame prevents vignetting even on wide-angle lenses, and the rotation mechanism is smooth and precise for easy adjustments.

Suitable for

• Landscape photographers capturing silky waterfalls, smooth clouds, or motion blur
