Haida 2 in 1 CPLVND Filter for Camera Pro II Multi-Coating Circular PolarizerVariable Neutral Density SLR Camera Lens Filter Waterproof Scratch Resistant Nano-Coating Filter 82mm

VND Effect: The Haida PROII CPL VND 2 in 1 Filter 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. Coating : This PROII CPL VND 2 in 1 Filter is constructed from optical glass for clarity as well as color fidelity. To prevent internal ghosting and reflections, the glass features eight layers of multi coating. These coatings also offer greater protection to a filter substrate and help it to stay clean for longer than with uncoated filters. Frame：Ultra slim aluminum alloy ring ensures durability while allowing the filter to remain lightweight. The thin, aluminum alloy filter ring minimizes the potential for vignetting, while remaining durable and lightweight.
