Vivitar 37mm Variable NDX Filter

The Vivitar Variable NDX Filter allows less light to pass through to your camera with and effect of ND2 to ND1000. Vivitar filters are made from high-quality optical glass and each individual filter is heat treated to prevent distortion. The Variable Neutral Density filter reduces the intensity of light evenly and without colour loss by ND 2 to 1000, giving you more control over your aperture/shutter speed and allowing you to use the largest aperture openings and long shutter speeds even in bright light. The Vivitar Variable NDX Filter is also great for use in video so you can always keep the shutter speed at 1/50.
