Variable 0.9-2.1 Neutral Density Filter Reduce Exposure by 3-7 Stops Filter Ring Rotation Lever Multi-Coated. The 77mm PROII CPL-VND 2-in-1 Filter from Haida is a variable neutral density filter that provides an exposure reduction of 3 to 7 stops. The 0.9 to 2.1 density creates a darkening of the entire image allowing you to photograph with a wider aperture or slower shutter speed than normally required. For easier repeatable control over density settings the front ring is also visually demarcated with dots that represent different density values and includes a rotation lever to further enable fast as well as precise positioning of the front ring.
