Neutral Density (ND) Variable Camera Filter K&F 82mm Adjustable ND8–ND2000 SB6582

Neutral Density (ND) Variable Camera Filter K&F 82mm Adjustable ND8–ND2000 SB6582 is a variable ND filter for lenses with an 82mm front thread. It provides continuous light attenuation from approximately ND8 to ND2000, allowing photographers and videographers to reduce light entering the lens without changing aperture or ISO. The filter is intended for controlling exposure in bright conditions, enabling longer shutter speeds for motion blur, or using wider apertures to achieve shallow depth of field in strong light.

Advantages

The variable ND design replaces multiple fixed ND filters by offering a smooth, stepless range of light reduction between low and very high densities. Compatibility with 82mm threads ensures direct attachment to lenses with that standard diameter, while the optical glass construction preserves image clarity and color balance when reducing exposure. The filter’s adjustable mechanism enables precise control of shutter speed and depth-of-field without altering camera settings that affect image noise or dynamic range.

Suitable for

• Landscape photography with long exposures to smooth water and clouds
• Video production to maintain cinematic shutter angles in bright environments
• Portraits shot in bright light where a shallow depth of field is desired
• Creative motion blur and light trails in daytime or dusk conditions

Key specifications

• Filter type: Variable neutral density
• Thread size: 82 mm
• Density range: approximately ND8 to ND2000 (continuous adjustment)
• Material: multi-coated optical glass (front element) and metal filter ring
• Primary use: photography and video exposure control

How to use

Mount the filter onto the front of an 82mm-thread lens by screwing it in until secure, taking care not to cross-thread. Rotate the outer ring to adjust the density from ND8 up to ND2000 while monitoring exposure or using the camera’s light meter. For long-exposure landscape work, set the camera on a stable tripod and use live view or a histogram to verify correct exposure. When recording video, adjust the filter to achieve the desired shutter speed or shutter angle while keeping aperture and ISO settings consistent for consistent depth of field and image quality.

Usage recommendations

Avoid extreme settings near the maximum density when using wide-angle lenses to minimize the risk of cross-polarization or uneven vignetting. Use a lens hood or secondary shading to reduce flare when shooting toward bright light sources. Regularly clean the filter with a microfiber cloth and appropriate lens cleaning solution to maintain optical performance.
