K&F Concept 77mm Nano X-Pro HD Variable ND2-400 Filter KF01.1618

K&F Concept 77mm Variable ND Filter ND2-ND400 (9 Stops)

Adjustable Neutral Density Filter

This variable ND filter allows precise light reduction from ND2 to ND400, providing up to 9 stops of light control. It features a putter design with each stop clearly marked on the frame for easy 360° rotation and adjustment, suitable for various shooting scenarios.

High-Quality Optical Glass

Constructed from premium Japan-made optical glass, the filter minimizes internal reflections and glare, ensuring crystal-clear image quality without affecting color or sharpness.

Advanced Nanotec Coating

Both sides of the glass are treated with state-of-the-art Nanotec multi-coating technology, making the filter waterproof, oil-proof, and scratch-resistant. This coating protects your camera lens during outdoor photography and maintains filter durability.

Ultra Slim Frame Design

The filter features an ultra-slim 7.4mm frame designed for ultra wide-angle lenses down to 16mm focal length, minimizing vignetting. Due to lens type and focal length differences, a dark "X" cross pattern may appear at certain settings; this is normal and can be eliminated by rotating the filter.
