K&F Concept Nano-X Variable ND 3-7 Stops Overview

This 3- to 7-stop, 72mm Nano-X Magnetic Variable ND Filter from K&F Concept allows you to quickly install the filter adapter ring on the lens thanks to its magnetic properties. The filter utilizes cutting-edge technology to avoid the common "X" cross on a wide-angle and telephoto lens. Both sides of the glass have nano-coating layers that make it waterproof, scratch resistant, and glare resistant, effectively protecting the camera lens.

This variable ND8-ND128 filter with magnetic technology can be installed in seconds for a faster installation than traditional thread filters.
The adapter ring has a thread to be screwed onto the lens. The ND8-ND128 magnetic filter engages in a magnetic way. Magnetic adapter rings are also suitable for other magnetic filters such as the magnetic CPL, magnetic ND8, magnetic black mist, and the magnetic ND1000 by K&F Concept.
K&F Concept utilizes cutting-edge technology (frame self-lock) to avoid the common "X" cross on a wide-angle and telephoto lens.
Both sides of the glass have nanometer coating (a total of 28 layers) that makes it waterproof, scratch resistant, and anti-glaring, effectively protecting the camera lens.
