This 1- to 5-stop Nano-X Green Multicoated Variable ND Filter from K&F Concept is a 49mm variable neutral density filter providing an adjustable light reduction of 1 to 5 stops. It darkens the entire image evenly, allowing a photograph to be made with a wider aperture or slower shutter speed than normally required. By slowing the exposure time or increasing the aperture, it is possible to control the depth of field and create motion blur, creating a dynamic look for streams, waterfalls, landscapes, and more. This multicoated variable neutral density filter does not affect the color of the image, and it features a waterproof and scratch-resistant coating for durable performance in the field.
