## Summary description

Adjustable variable neutral density (ND) filter by K&F with 67 mm thread, offering a density range from ND2 to ND400. The gray (neutral) glass reduces light intake for long exposures, wider apertures and motion blur control without changing color balance. Suitable for landscape, long exposure, and videography applications; fits lenses with 67 mm filter threads.

## Long description

The Variable ND Filter K&F 67mm adjustable ND2–ND400 gray (model SB7796) is a neutral density filter with a 67 mm thread that provides continuous attenuation of light from approximately 1 to 9 stops. Constructed with gray neutral glass, it reduces the amount of light reaching the sensor without altering color balance, enabling longer exposures, wider apertures and controlled motion blur. The filter is suitable for landscape photography, long exposure shots and video production where flexible light reduction is required and quick adjustment is preferred over swapping fixed-density filters.
Advantages
The adjustable ND2–ND400 range offers a wide, continuous density span in a single filter, avoiding the need to carry multiple fixed ND filters. Neutral gray glass maintains natural color rendering while decreasing exposure. The 67 mm screw thread ensures compatibility with lenses that accept 67 mm filters, and the slim profile helps minimize vignetting on wide-angle lenses. The variable mechanism allows fine control over exposure and motion effects without interrupting shooting to change filters.
Suitable for
Landscape photography requiring long exposures for smooth water and cloud motion
Portraits and outdoor shoots using wide apertures in bright light
Videography and filmmaking where consistent, adjustable light reduction is needed
Urban and architectural long-exposure shots to blur people or traffic
Key specifications
Filter type: Variable neutral density (ND)
Density range: approximately ND2 to ND400 (about 1 to 9 stops)
Thread size: 67 mm
Optical material: neutral gray glass
Profile: slim design to reduce vignetting on wide-angle lenses
Control: continuously adjustable density via rotating ring
How to use
Screw the filter onto a lens with a 67 mm filter thread until it is secure but not overtightened. Set the filter to the minimum density before composing and metering, then rotate the adjustable ring slowly to increase light attenuation until you achieve the desired exposure or motion effect. When using long exposures, use a tripod and mirror lockup or electronic shutter options if available to reduce camera shake. Check the viewfinder or live view for potential cross-polarization artifacts when using strong density settings and adjust rotation slightly if necessary.
Usage recommendations
To avoid X-pattern or uneven darkening at extreme settings, avoid using the maximum density range for very wide-angle lenses; stop down aperture or use slightly lower density settings if cross-polarization appears. Store the filter in a protective case and clean with a microfiber cloth and appropriate filter cleaner to maintain optical performance.
