Improve your photography with the HOYA ND 8X PROND 58mm ND filter. The filter's main advantage is that it reduces the amount of light passing through the camera lens, allowing you to use a longer shutter speed. It also captures objects in motion and adds a blurred effect. Another neat bonus of 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 HOYA ND 8X PROND 58mm ND Filter has a 58 mm filter diameter, so it's compatible with many different lenses. The ND factor of 8 indicates a light transmittance of 13%, i.e. a 8x longer exposure time.
