Concept 67mm Variable ND Light Attenuation 11 Levels AGC Optical 18 Layer Thin 3 Cleaning Cloths Ideal for Video Shooting K&F ND2-2000 Filter,

[Nano-Klear Variable ND Filter] The variable ND filter of K&F Concept ND2-2000 can adjust the light intensity in 11 steps from ND2 to ND2000, and the density of the neutral density filter can be adjusted at any time as needed to adapt to different light environments. (Please note: Nano-Klear filters are non-HD lenses and cannot be used for telephoto shooting. The cap is one size larger than the variable ND filter diameter. A hood cannot be attached to this product.) [Optical Glass/18 Layer Coating] The variable ND filter uses high quality Japanese-made optical glass coated with 18 layers, which effectively suppresses 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. [Thin Frame Type] The frame thickness of the ND filter is 7.4mm thin, which prevents vignetting even with a wide-angle lens, and the surface is made of CNC trapezoidal pattern design pattern, which increases friction with a large area while rotating, ensuring that lenses and other accessories can be attached and detached. [Includes 3-piece vacuum packaging cloth] 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. [Note] 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.
