K&F Concept Variable ND Lens Filter -------Extend exposure time. Try an ND, or neutral density, filter. ND filters reduce the amount of light entering the lens. This makes it easier to achieve effects such as a shallower depth of field or blurred motion. Neutral density can be adjusted from 2 to 5 stops, easy to create different neutral density by rotating the ring. The front diameter is larger than the back diameter of this filter , which is specially designed to avoid vignetting at wide angle lens. Allows the use of slow shutter speeds, with high speed films or digital cameras, to record movement/image blur in subjects. Decrease the depth of field by using wider apertures, which helps separate subjects from their background. Note: The front diameter is larger than the back diameter of this filter. Eg. for the 82mm nd filter, the lens cap/hood size should be 86mm.
