K&F Concept Nano-X Series Variable ND Filter (72mm, 1 to 5-Stop)

Overview

The K&F Concept Nano-X Series Variable ND Filter (72mm, 1 to 5-Stop) is a versatile neutral density solution designed to provide precise exposure control for both photography and videography. By rotating the slim aluminum ring, creators can smoothly adjust density from 1 to 5 stops, enabling wider apertures, slower shutter speeds, and refined depth-of-field control across various shooting environments.

Core Features

• Variable density range of 1 to 5 stops.
• Smooth exposure adjustment via rotating ring.
• No “X” cross artifacts on wide-angle lenses.
• Darkens the full image for consistent exposure control.
• Supports slow shutter speeds and wider apertures.
• Ideal for motion blur, depth-of-field, and video frame-rate control.

Optical Performance

Japanese Optical Glass

Constructed using premium Japanese optical glass, this filter ensures high-resolution imaging with accurate color reproduction and optimal light transmission.

28-Layer Nano & Resistance Coating

Its 28-layer nanometer multicoating minimizes flare and glare while repelling water, dust, salt, and fingerprints. The protective resistance coating delivers durability in harsh outdoor environments.

Design & Build

Ultra-Slim Aluminum Ring

The aviation-grade aluminum frame features a slim profile to reduce vignetting, with a knurled edge and marked density scale for secure, precise adjustments. The front of the filter is threadless for reduced wind resistance and minimal optical interference.
