This 77mm Three-Piece Solid Neutral Density Filter Kit from Vivitar contains three filters that can be used individually or in various combinations to create a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than normally required. By slowing your exposure time or increasing your aperture, you are able to control depth of field and convey movement more easily. Neutral density filters do not affect the coloration of the image and are ideal for pairing with other filters.
The included filters consist of 77mm solid neutral density filters that reduce the amount of light entering a lens by one, two, and three stops, respectively. Each filter is constructed using an aluminum-alloy frame, which can help protect the front element of a lens from scratches, bumps, or impacts.
