K&F CONCEPT Variable ND3-ND1000 ND Filter (1.5-10 Stops) Neutral Density Lens Filter with 24 Multi-Layer Coatings

ND3-ND1000 Filter Function
Variable nd1000 reduces the amount of light passing through the lens or extends the shooting time when using a large aperture to shoot in places with intense light.

Premium Material
Made of high-quality Japanese optical glass, 360 degrees rotating between 1.5 to 10 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, mold, 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.
