Concept 37mm TRUE COLOR Variable ND filter Can eliminate yellow cast Brightness adjustment 9 levels adjustable Optical glass coating Thin frame

[Can eliminate yellow tint] TRUE COLOR ND2-400 filter adopts a new titanium coating technology, which effectively solves the problem of yellow tint on the screen during video recording, allowing you to reproduce the original color. (Please note: Nano-Klear filters are non-HD lenses and cannot be used for telephoto shooting.) [NANO-K Variable ND Filter] The variable ND filter of K&F Concept TRUE COLOR 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. [18-Layer Coating] The variable ND filter uses 18-layer coated high-quality optical 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. [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.
