The Haida 77mm PROII Variable ND Filter is a solid variable neutral density filter that provides an exposure reduction of 2 to 5 stops. The 0.6 to 1.5 density creates a darkening of the entire image, allowing you to video or 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.

• 3 Stop Neutral Density Hard Graduation Filter
• Shock-resistant optical glass construction
• 10 layers of anti-reflective nano coatings on each glass surface prevent internal ghosting and reflections, while further enhancing clarity and colour fidelity
• 10 additional scratch-resistant hydrophobic coatings on each glass surface further protect the filter substrate and result in an improved beading effect when in contact with water or oil for greater cleaning efficiency
• Rounded edges for easier placement within a compatible filter holder slot
• Metallic filter case for storage and transport
