K&F CONCEPT 77mm Variable ND3- ND1000 Filters Adjustable 10 Stop ND Neutral Density Filters for DSLR Camera Lens (Nano-D Series)

Product Features

• ND3-ND1000 Filter Function: Variable nd1000 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 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, 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.
• Note: the letter MIN on frame represents ND3, MAX represents ND1000, the amount of light reduction can be adjusted in 11 steps. The main reason for the scale is to record the dimming value in shooting and does not represent the specific ND value.
