Description Product Description Fotodiox Pro 186mm Slim ND4 Filter is a true neutral density filter designed to darken the image by 2 stops. The filter is double threaded and thinner than a standard filter to minimize any possibility of vignetting when used with a WonderPana 186 filter system. It features an even, neutral grey colour for creative photography applications. ND4 filter offers a 2-stop EV value which allows you to slow down the shutter speed or use a larger aperture in bright light conditions.
