K&F SLIM Variable ND Filter 9 stops

This Filter from K&F Concept is a variable neutral density filter providing an adjustable light reduction of 1 to 9 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 convey blurred movement easily, creating a dynamic look for streams, waterfalls, landscapes, and more. This multicoated variable neutral density filter does not affect the coloration of the image, and it features a waterproof and scratch-resistant coating for durable performance in the field.
