The 95mm Power XND Mark II 5 to 11-Stop Variable ND Filter from Aurora Aperture is a variable neutral density filter that is designed to mount onto lenses with 95mm front filter threads and provides an exposure reduction of 5 to 11 stops. Its 1.5 to 3.3 neutral density filter factor creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than normally required. The degree of density is easily controlled by rotating the front filter ring, helping you to predetermine the additional exposure length required. By increasing your aperture or slowing your exposure time, you are able to control depth of field and convey movement more easily. For easier, repeatable control over density settings, the front ring is visually demarcated with numbers representing different density values and includes a rotation lever to further enable fast and precise positioning of the front ring.
This filter is constructed from Schott B270 glass for increased optical clarity as well as color fidelity, and each glass surface is multicoated to prevent ghosting as well as reflections. The nano coating associated with the 95mm Power XND Mark II Variable Neutral Density Filter provides an additional layer that allows for more efficient cleaning when its surfaces come in contact with dust, dirt, water, or oil.
