Neutral Density Variable Camera Filter K&F FADER 82 mm Nano-C ND2–ND2000 (82mm)

The Neutral Density Variable Camera Filter K&F FADER 82 mm Nano-C ND2–ND2000 is a rotating variable ND filter with an 82 mm front thread. It offers an adjustable attenuation range equivalent to ND2 up to ND2000, allowing progressive reduction of light entering the lens. The Nano-C coating improves surface resistance to water, oil and dust and helps maintain image contrast and color neutrality across the density range. This filter is designed to support longer exposures, controlled motion blur and shallower depth-of-field effects when ambient light would otherwise be excessive.

Advantages

The variable density mechanism provides continuous control between low and high attenuation without swapping filters, enabling precise exposure adjustments in changing light. The 82 mm thread fits lenses with matching diameter and the slim profile helps reduce vignetting on wide-angle lenses. Nano-C multi-coating reduces reflections and eases cleaning while preserving accurate color rendition and contrast at different density settings.

Suitable for

• Landscape photography requiring long exposures for smooth water and cloud motion
• Architectural and urban scenes where motion blur is used creatively
• Videography and time-lapse work needing consistent light attenuation
• Portraits and shallow depth-of-field work in bright conditions

Key specifications

• Filter type: Variable neutral density (rotating)
• Thread size: 82 mm (front thread for attachment)
• Density range: Variable from approximately ND2 to ND2000 (progressive attenuation)
• Coating: Nano-C multi-coating for reduced reflections and easier cleaning
• Construction: Slim profile design to minimize vignetting on wide-angle lenses
• Material: Optical glass elements with metal filter ring

How to use

Attach the filter to a lens with an 82 mm thread by screwing it into place until secure. Rotate the front element to adjust the density continuously from light reduction equivalent to ND2 up to ND2000 while observing exposure changes through the viewfinder or on the camera monitor. Check for cross-polarization or X-patterns at extreme settings by testing in the field; if artifacts appear, reduce the maximum rotation. Use a tripod for long exposures and verify focus and composition before applying very high attenuation values.

Usage recommendations

For best results, set white balance after attaching the filter or use manual white balance to maintain color consistency. When shooting video or long exposures, use incremental adjustments and test exposures to find the optimal density. Keep the Nano-C coated surfaces clean with a soft microfiber cloth and store the filter in its case when not in use to protect the coating and thread.
