Aurora-Aperture 95mm PowerXND 2000 Variable Neutral Density 1.2 to 3.3 Filter (4 to 11 Stops)

TheAurora Aperture 95mm PowerXND 2000 Variable Neutral Density 1.2 to 3.3 Filteris a solid variable neutral density filter that is designed to mount onto lenses with 95mm front filter threads and provides an exposure reduction of 4 to 11 stops. The 1.2 to 3.3 density 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 slowing your exposure time or increasing your aperture, you are able to control depth of field and convey movement more easily. For easier, repeatable control over density settings, the rear ring is visually demarcated with dots that represent different density values while the front ring includes knurling to further enable fast and precise positioning.

This filter is constructed from optical glass for clarity and color fidelity. To prevent internal ghosting and reflections while maximizing light transmission, each glass surface includes eight layers of anti-reflection nano coatings. These coatings offer greater protection to the filter substrate and help it to stay clean for longer than with uncoated filters as well, while resulting in an improved beading effect when in contact with water for greater cleaning efficiency.
