The GB Optics 62mm Slim Variable Neutral Density 0.3 to 3.3 Filter is a solid variable neutral density filter that provides an exposure reduction of 1 to 11 stops. The 0.3 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 front ring is also visually demarcated with dots that represent different density values.

This GB Optics variable neutral density filter is constructed from optical glass for clarity and color fidelity. It also features an 67mm front mount which helps to reduce the likelihood of vignetting when used with wide-angle lenses.
