K&F Concept 82mm Nano-X Soft-Edge GND16 1.2 4-Stop Filter

GND16 (1.2) 4 stops filter made of top optical galss, provides up to a 4-stop reduction in light in selective areas.Reduce the amount of light entering the lens, but not affect the overall coloration of the image.Precision grinding and double-sided polishing. It will not affect the sharpness on the telephoto lens, ensuring high-definition imaging. Soft-Edge Graduated Neutral Density 1.2 Filter darkens bright areas of an image, such as skies, while the remaining regions of the image are exposed with a progressively decreasing effect.With a soft-edged line of transition is particularly useful for images that do not have a strongly defined transition between the sky and the foreground.The surface of the frame is designed with CNC trapezoidal patterns to ensure a large area of friction when rotating, and the lens and other accessories can be installed/removed anytime and anywhere.The thin frame design is only 5.3mm, and ensures that there will be no vignetting at the wide-angle end and the telephoto end.
