Optics Glass: This filter is constructed from optical glass for clarity as well as color fidelity. Precise Adjustment 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. ND8 To ND128 Adjustable Filter Haida 72mm VND CPL 2 In 1 ND8-ND128 Adjustable Filter (3-7 Camera Filter Rotate the outer frame to adjust the polarization angle. Haida 82mm PROII 0.9-2.1 3-7 Stops Multi-Coated CPL-VND 2-In-1 Filter This is extremely beneficial for achieving deeper tones in foliage and water when shooting landscapes, seascapes, and moving water. Waterproof To prevent internal ghosting and reflections, the glass features eight layers of multi-coating. Multi Coating: Multi-coating offers greater protection to a filter substrate and results an improved beading effect when the surface comes in contact with water or oil, allowing for more efficient cleaning. Simultaneously, the circular polarizer component of this filter can reduce reflections, glare, and the haze caused by scattered light. Aluminum Alloy Frame The Haida filter's frame is ultra-slim aluminum alloy ring ensures durability while allowing the filter to remain lightweight. Haida 67mm NanoPro Variable ND Filter - Photo4B For example, if you get the 67mm filter, you need a 72mm filter to add into the front of it. Haida PROII CPL-VND 2 in 1 Filter with 3-7 Stops ND8 ND128 for Camera... Aluminum Alloy: The lens filter comes with an aluminum alloy frame that gives better protection.
