The 82mm 2-in-1 Variable ND4-ND64 (2-6 Stop) & CPL Filter from the Nano-X series by K&F Concept is a versatile accessory for photographers and videographers. This filter combines the functions of a variable neutral density filter (ND) and a circular polarizing filter (CPL), making it a practical tool for controlling lighting conditions and reflections. With an adjustable ND range of 2 to 6 stops, it allows for precise exposure adjustments, while the CPL filter reduces unwanted reflections from non-metallic surfaces and enhances color saturation. The filter features a special green coating that not only optimizes light transmission but also provides water-repellent and scratch-resistant properties. This 28-layer coating ensures high image quality and protects the filter from environmental influences. The filter is ideal for landscape, portrait, and architectural photography, as well as for video recordings under various lighting conditions.
