Concept 67mm Variable ND Light Attenuation 9 Levels Lens Cap Optical 18 Layer Thin Cleaning Cloth Ideal for Video Shooting K&F ND2-ND400 Filter,

📷【NANO-K Variable ND Filter】The variable ND filter of K&F Concept ND2-ND400 can adjust the light intensity in 9 levels from ND2 to ND400, and the density of the neutral density filter can be adjusted at any time as needed to adapt to different light environments. (⚠️This variable ND filter is not suitable for use with telephoto lenses. A lens hood cannot be attached.) 📷【18-layer coating】The variable ND filter is made of high-quality optical glass with 18-layer transparency-enhancing coating on both sides, which can effectively reduce the reflected light on the filter surface. 📷【In-house developed lens cap】Comes with a high-quality lens cover and adopts an innovative non-spring structure to avoid problems such as spring deterioration. The inner-type structural design allows it to be attached to fit a variety of lenses. 📷 [3 pieces of vacuum packaging cloth included] The included cleaning cloth is made of microfiber and will not damage the coating of optical equipment such as lenses and lens filters. Even stubborn oil films and sebum stains can be easily removed. 📷[Caution] ⚠️If the variable ND filter is on the high stage side, X-shaped unevenness is likely to occur. The location of the unevenness varies depending on the type of lens used and focal length. Keep rotating the filter and the shadows will disappear naturally. This phenomenon is not a quality issue, but a natural physical phenomenon caused by the rotation of the variable ND.
