K&F CONCEPT 55mm Variable ND2 400 Filter + Lens Cap +Cleaning Cloth, Slim ND for Camera

Variable ND2-ND400: ND2-400 filters reduce light intake from 1 to 8.66 f-stops, allowing slower shutter speeds and wider apertures, which is especially suitable for rivers, waterfalls and other waters, especially under strong light. Snap-On Lens Cap: The lens cover is made of premium ABS, an environmentally friendly material, lightweight and durable. Elastic lens cap strap for better hold. HD Optical Glass with Multi-coating: This adjustable ND filter is made of HD AGC optical glass, a total of 18 multi-layer coatings, which effectively reduces reflection from the filter itself and avoids glare, ensuring a high-quality image. Non-Slip 7.4mm Thin Frame: 9 stop ND designed with CNC trapezoidal pattern, which increases the friction in rotation and allows you to install/remove easily. The index marks on the filter let you know the exact stops of ND at a glance. Package contents: 1x variable ND2-400 filter, 1x centre pinch lens cap, 1x cap keeper, 1x cleaning Cloth, 1x filter case.
