## Summary description

Variable neutral density (ND) filter by K&F in 77 mm size providing adjustable light reduction from approximately ND3 to ND1000. Designed for controlling exposure and motion blur in photography and long-exposure shots, it fits lenses with 77 mm thread. Useful for landscape, seascape, and video work to achieve slower shutter speeds or wider apertures in bright light.

## Long description

The Neutral Density Variable Filter K&F 77mm ND3–ND1000 is an adjustable 77 mm screw-in filter that provides continuous light reduction from approximately ND3 to ND1000. It is designed to give photographers and videographers precise control over exposure and motion blur without changing aperture or ISO. The filter is suitable for creating long-exposure effects in landscape and seascape photography, reducing shutter speed in bright light, or enabling shallower depth of field in daytime shooting.
Advantages
This variable ND filter offers a wide attenuation range in a single unit, eliminating the need to carry multiple fixed-density filters. The 77 mm threaded design ensures compatibility with lenses that accept 77 mm filters, and the adjustable mechanism allows smooth, gradual changes in light transmission. The compact, screw-in form factor preserves optical alignment and minimizes additional weight on the lens.
Suitable for
 Landscape and seascape long-exposure photography
 Video production to control exposure and motion blur in daylight
 Portraits and outdoor shoots requiring wider apertures in bright conditions
 Creative motion blur effects for waterfalls, clouds, or moving subjects
Key specifications
 Filter type: Variable neutral density (continuous ND)
 Density range: approximately ND3 to ND1000 (adjustable)
 Mount: screw-in, 77 mm filter thread
 Construction: multi-element optical glass with rotating polarizing element (variable ND design)
 Finish: low-profile metal ring to reduce vignetting on wide-angle lenses
How to use
Screw the filter onto a lens with a 77 mm thread until it is secure but not overtightened. Adjust exposure settings on the camera first for the scene, then rotate the outer ring of the filter to increase or decrease light reduction until the desired shutter speed or aperture is reached. For long-exposure landscape shots use a tripod to prevent camera shake. Check the viewfinder or live view for exposure and color shifts, and fine-tune the filter position as needed.
Usage recommendations
Use the filter with a tripod for exposures longer than 1/30 s to avoid blur from camera movement, and be aware that extreme density settings can introduce color casts; bracket exposures or apply white-balance adjustments in post-processing if necessary.
