The K&F Concept 1/4 Black Mist Filter Nano X with a diameter of 72 mm is a professional optical filter designed for portrait photography and video recording. This black soft 1/4 filter effectively softens skin imperfections such as wrinkles, freckles, and pores while maintaining overall image sharpness, resulting in a more delicate and refined skin texture. The filter produces a subtle, dreamy film effect with controlled diffusion that enhances cinematic quality without compromising image clarity. Made from high-quality Japanese AGC optical glass, the filter undergoes double polishing processes for high-resolution performance up to 550 mm focal length. The optical glass features 28 multi-layer coatings that provide water-repellent, scratch-resistant, and oil-repellent properties while maintaining a consistent light transmission of 84 percent. The ultra-thin frame made of aircraft-grade aluminum measures only 3.3 mm in width, preventing vignetting and dark corners even when used with wide-angle lenses and long focal lengths. The CNC-machined frame has rounded edges with an improved grip for easy adjustment and secure handling. This 72 mm filter is compatible with all lenses that have the corresponding thread diameter and is recommended for video recordings where controlled diffusion and skin softening effects are desired. Please check the thread size of your camera lens before purchasing, which is typically marked on the lens barrel or lens cap, to ensure proper compatibility.
