This 55mm Nano-X Soft-Edge Graduated ND Filter from K&F Concept is a glass filter that provides up to a 4-stop reduction in light in selective areas. The filter darkens bright areas of an image, such as skies, while the remaining areas of the image are affected progressively less. The soft-edge transition is especially useful when there isn't a well-defined separation between bright and dark areas of your shot. Featuring dual-sided multicoating, the filter is waterproof, oilproof, and scratch resistant.

The frame of the filter is only 5.3mm thick, ensuring there will be no vignetting at the wide-angle and telephoto ends. It has a nonslip grip that allows you to rotate it with precision. This filter does not have front filter threads.
