Concept 52mm variable ND filter Light attenuation adjustment unevenness control Variable AGC optical glass coating Water repellent and stain resistant

[5-level adjustment & X-shape unevenness control] The frame of the K&F Concept variable ND filter uses self-locking technology, and the 5-level dimming adjustment function from ND2 to ND32 allows it to adapt to a wide range of weather conditions. At the same time, it avoids the phenomenon of X-shaped unevenness. (⚠️Double structure, so if the variable ND filter is 52mm, the lens cap will be 55mm.) [Optical Glass] The variable ND2-ND32 filter uses 24 layers of nano-coated Japanese AGC glass, which effectively suppresses the reflected light on 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. [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. [ND2-ND32 variable type] This neutral density filter can be adjusted to 5 levels with one filter, saving you the hassle of carrying multiple filters and stacking them. While creating a variety of original expressions, you can also use a slow shutter even in environments with strong light to create a sea of clouds, the smooth flow of water in a waterfall, and the leaving of light trails.
