Become a master of light manipulation with the 77mm Nano-x Nd2-32 1-5 Stop Magnetic Variable Neutral Density Lens Filter from KandF Concept. This innovative lens filter offers a seamless 1-second swap feature, eliminating the need for screwing on the lens and ensuring you never miss capturing a perfect moment. The KandF Concept Magnetic Variable ND filter is designed to extend exposure time, making it an ideal tool for photographers who want to capture the beauty of motion blur or achieve a shallower depth of field. By reducing the amount of light entering the lens, this neutral density filter allows you to control light reduction from 1 to 5 stops simply by rotating the filter. Designed with the wide-angle lens photographer in mind, this filter features a front diameter larger than its back diameter, effectively eliminating vignetting.
