Improve your photography with the HOYA ND 8X PROND 82mm ND filter. The most notable feature of the ND (neutral-density) filter is that it partially blocks light coming into the lens, allowing you to use a longer shutter speed. It also captures objects in motion and adds a blurred effect. Another interesting effect of ND filters is that you can use a wider aperture for a more intense depth of field effect. The HOYA ND 8X PROND 82mm ND Filter has a 82 mm filter diameter, so it's compatible with many different lenses. The ND factor of 8 indicates a transmittance of 13%, so you can set up a 8x longer exposure.
