Become a better photographer with the Starblitz neutral grey filter 1000x 52mm ND filter. The filter's main advantage is that it reduces the amount of light that ends up on the camera’s sensor, allowing you to use a longer shutter speed. It also captures objects in motion and adds a blurred effect. Another great feature of all ND filters is that you can use a wider aperture with the same ISO sensitivity and shutter speed for a more intense depth of field effect. The Starblitz neutral grey filter 1000x 52mm ND Filter has a 52 mm filter diameter, so it's compatible with many different lenses. The ND factor of 1000 indicates a light transmittance of 0.1%, so you can set up a 1000x longer exposure.
