K&F Concept 82MM C Series Ultra-thin Variable/Fader,ND2-2000 Blue Coated

"ND2-ND2000 Filter Function — Variable nd2000 is to reduce the amount of light passing through the lens or extend the shooting time when using a large aperture to shoot in places with strong light.
* Premium Material — Made of high-quality Japanese optical glass, 360 degrees rotating between 1to 11 stops, it can effectively reduce the reflection of the filter surface and avoid image defects.
* Multi-coatings — The double-sided multi-layer coating and polishing effectively minimize reflections from the filter self and resistance to water, mould, dirt, and scratches.
* Extremely Slim — The filter frame is only 7.4mm, super lightweight CNC-non slip frame helps install and remove the filter quickly and easily. Vignetting can be effectively avoided when taking wide-angle shots."
