The Nano-X Series 2-in-1 True Color Variable ND & CPL Filter from K&F Concept ensures true color reproduction while providing 1 to 5-stops of light reduction, reducing glare and reflections from non-metallic surfaces, and increasing saturation and vibrancy in the sky and foliage. A tabbed ring design makes it possible to adjust the CPL and VND independently for the ideal exposure in any scene. The 28-layer nanometer coating helps to reduce unwanted reflections and provides a waterproof and scratch-resistant layer to assist in the cleaning of unwanted fingerprints, dust, and water stains. This filter removes the yellow tone and black cross in frame seen with other brands of CPL filters and provides a closer true color representation of the scene.
