## Summary description

Variable neutral density (ND) filter K&F 77mm KF X Fader with adjustable density range ND8–ND128. Designed to reduce light entering the lens without affecting color balance, it enables longer exposures and wider apertures in bright conditions. Fits 77mm front threads and is used for motion blur, light streaks, and controlling depth of field in landscape, architecture, and video work.

## Long description

Variable Neutral Density Filter K&F 77mm KF X Fader ND8–ND128 (Adjustable, Gray) is a screw-on optical filter that reduces the amount of light entering the lens across a wide, continuously adjustable range. Compatible with lenses that have 77mm front threads, this variable ND filter provides smooth attenuation from approximately 3 to 7 stops (ND8 to ND128) without altering color balance, allowing photographers and videographers to use slower shutter speeds or wider apertures in bright conditions. The compact gray filter is suitable for landscape, architecture, street photography and video production where control over exposure and depth of field is required.
Advantages
The K&F adjustable ND filter offers stepless density control within a large range, enabling precise exposure adjustments without changing filters. Its neutral gray optical glass preserves accurate color rendition and contrast across the frame. The threaded metal mount ensures secure attachment to the lens, and the slim profile helps reduce vignetting on wide-angle lenses. This filter simplifies the workflow for long-exposure photography and for creating motion blur or light streaks while maintaining overall image quality.
Suitable for
 Long-exposure landscape photography to smooth water and clouds
 Creating motion blur in urban scenes and traffic light trails
 Using wide apertures in bright light to control depth of field
 Video shooting where consistent shutter angles and slower shutter speeds are required
 On-location work with lenses that accept 77mm front threads
Key specifications
 Filter type: Variable neutral density (adjustable ND)
 Density range: ND8 to ND128 (approx. 3 to 7 stops)
 Thread size: 77 mm front thread
 Color: Gray, neutral density glass to maintain color balance
 Mount: Screw-on metal mount with slim profile to minimize vignetting
 Use: Designed for both photo and video applications
How to use
Attach the filter by screwing it onto the lens front threads until it is snug but not overtightened. Rotate the front ring to adjust the density gradually; observe exposure changes in the viewfinder or on the camera monitor and set the shutter speed or aperture according to the desired creative effect. When using the filter for long exposures, use a tripod and, if possible, mirror lock-up or electronic front-curtain shutter to reduce camera shake. Store the filter in its protective case when not in use to prevent scratches or contamination.
Usage recommendations
To avoid cross-polarization effects and uneven darkening (X-pattern) at extreme settings, avoid stacking multiple variable ND filters and limit adjustment to the range that produces uniform density. For best results in critical color and sharpness-sensitive work, check exposure and white balance and consider using a fixed-stop ND filter if maximum density or absolute uniformity is required.
