Concept 77mm Variable ND Filter Light Attenuation Adjustment Stepless Adjustable AGC Optical Glass 24 Layer Coating Water Repellent and Stain

[NANO-D Variable ND Filter] The 77mm variable ND2-ND400 filter uses 24 layers of nano-coated Japanese AGC glass to effectively suppress reflected light from the lens filter surface. This greatly reduces the occurrence of flare caused by anti-reflection on the outside of the lens due to long exposures, and does not affect imaging. (⚠️Double structure, so if the variable ND filter is 77mm, the lens cap will be 82mm.) [360° stepless adjustment] Can be adjusted from 1 to 9 levels, and can be rotated 360 degrees to adjust the dimming level, so it can be used in multiple scenes. (⚠️X-shaped unevenness is more likely to occur when using a variable ND filter at a high stage. The position of the unevenness varies depending on the type of lens used and focal length. If you continue to rotate the filter, the shadow will disappear naturally. This phenomenon is not a quality problem, but a natural physical phenomenon caused by the rotation of the variable ND.) [Multi-layer waterproof coating] The variable ND filter uses a multi-layer waterproof coating, so if you accidentally splash water on the filter, the water droplets will solidify instead of scattering, making it easy to carry and clean. 【Thin Frame Design】The thickness of the frame is only 7.4mm, and the surface is made of CNC trapezoid pattern design pattern, which increases friction with a large area while rotating, ensuring that you can attach and detach lenses and other accessories. [CNC & anti-slip knurling] CNC integral molding combines hardness and flexibility, making installation smooth. The outer frame of the lens filter is also knurled to prevent slipping so that it can be easily attached to and removed from the lens.
