The Hoya 67mm Variable Density x3-400 Filter is a lightweight and solid variable neutral density filter that provide an exposure reduction of about 1.5 to 9 stops. The 0.45 to 2.7 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than would normally be required. The degree of density is easily controlled by rotating the front filter ring, helping you to predetermine the additional exposure length required. By slowing the exposure time or increasing your aperture, user are able to control depth of field and convey movement more easily. This filter is constructed from optical glass to maintain image clarity and is set within a slim profile aluminum ring that helps to reduce the likelihood of vignetting when used on wide-angle lenses and does not feature front threads.
