Neutral Density Filter K&F Adjustable ND3–ND1000, 82mm

The K&F Adjustable Neutral Density Filter ND3–ND1000 in 82mm thread is a variable-density photographic filter that provides continuous control of light transmission between approximately 1 and 10 stops. Designed to mount on lenses with an 82 mm front thread, this filter enables longer exposures, controlled motion blur and wider aperture use in bright conditions while preserving the scene's color balance. The filter construction delivers even attenuation across the frame and is compatible with landscape, long-exposure and video shooting workflows.

Advantages

This adjustable ND filter offers a smooth, continuous range from light reduction equivalent to ND3 up to ND1000, allowing precise exposure adjustments without swapping filters. Its optical glass and multi-coating reduce reflections and ghosting, maintain contrast and help prevent color shift. The 82 mm threaded mount fits lenses with that diameter and the slim profile minimizes vignetting on wide-angle lenses. The filter’s build balances optical performance with convenient in-field adjustment for stills and video.

Suitable for (tasks / use cases)

• Landscape photography requiring long exposures to smooth water and clouds
• Motion blur effects for waterfalls, rivers and urban traffic
• Videography needing controlled shutter speed and shallow depth of field in bright light
• Portraits or wide-aperture shooting outdoors to achieve shallow depth of field

Key specifications

• Filter type: Adjustable (variable) neutral density
• Light reduction range: continuous from ND3 to ND1000
• Thread size: 82 mm
• Optical material: multi-coated glass
• Profile: slim design to reduce vignetting on wide-angle lenses

How to use

Attach the filter to the front of an 82 mm lens thread and secure it by screwing until lightly snug. Set the camera on a tripod for long exposures or controlled motion shots. Rotate the filter ring to adjust the density until the desired exposure or shutter speed is achieved; use the camera’s meter or a handheld light meter to verify exposure. When using wide apertures or long exposures, check for vignetting and, if necessary, stop down slightly or use a lens hood compatible with the filter. For video work, adjust the density to maintain the chosen shutter angle or shutter speed while keeping ISO and aperture constant.

Usage recommendations

To minimize uneven darkening at high density settings, compose and test exposures before critical takes; if visible banding or X-pattern appears at extreme settings, reduce the density slightly or use a fixed neutral density filter for very long exposures. Store the filter in its protective case when not in use and clean with a soft microfiber cloth and appropriate lens cleaner to maintain coatings and optical clarity.
