Enables slow shutter speeds to be used, allowing film to record movement in subjects such as waterfalls, clouds, or cars. Decrease depth of field by allowing wider apertures to be used, in turn helping to separate subjects from their background. Decrease the effective ISO of high-speed film and allow it to be used outdoors in bright situations. Allows video cameras (which have fixed shutter speeds) to film subjects such as snow, sand or other bright scenes that can cause overexposure. 24-Month Manufacturer Warranty
