K&F Concept Nano-X Series 2-in-1 True Color Variable ND & CPL Filter (77mm, 1 to 5-Stop)

K&F Concept Nano-X 77mm Variable ND & CPL Filter Overview

The K&F Concept Nano-X Series 2-in-1 True Color Variable ND & CPL Filter in 77mm combines exposure control and polarization in a single filter for lenses with a 77mm front thread. It provides 1 to 5 stops of variable light reduction while helping reduce reflections and improve color and tonal saturation.

The variable ND and circular polarizer functions can be adjusted independently using the tabbed ring design. This allows photographers and filmmakers to control exposure, reduce glare from non-metallic surfaces and enhance skies or foliage without stacking separate filters.

True Color technology is designed to maintain a more neutral color response while minimizing the warm cast that can occur with some variable ND filters. The optical design also helps avoid unwanted cross-pattern effects during normal adjustment.

AGC optical glass is protected by a 28-layer nano coating that helps reduce reflections while adding resistance to water, scratches, fingerprints, dust and other contaminants. The 77mm diameter makes this version a practical fit for compatible professional lenses using a mid-size filter thread.
