40.5mm Variable ND Filter, Adjustable Neutral Density ND2 to ND400, Slim Threaded Camera Lens Filter with Storage Case - Black

40.5mm screw-in variable neutral density filter for camera lenses with a 40.5mm filter thread. Turn the outer ring to set the density anywhere from ND2 to ND400 (about 1 to 8.6 stops) without changing filters. Cuts the light reaching the lens so you can use slower shutter speeds or wider apertures in bright light, for smooth water, motion blur and shallow depth of field. Slim aluminium frame with a front thread so other filters or a lens cap can be fitted on top. Package contents: 1 x variable ND filter, 1 x storage case (camera and lens not included).
