## Summary description

Variable neutral density (ND) lens filter from K&F with a 46 mm thread size, adjustable between ND8 and ND128. Provides controllable light reduction for stills and video, enabling longer exposures, wider apertures in bright conditions, and motion blur effects. Designed for screw-in attachment to compatible 46 mm lenses; useful for landscape, long exposure, and cinematography workflows.

## Long description

The Lens Variable ND Filter K&F 46mm Adjustable ND8–ND128 is a screw‑in neutral density filter designed for lenses with a 46 mm thread. It provides continuous light reduction across a wide range from approximately 3 stops (ND8) up to 7 stops (ND128), allowing precise control of exposure for still photography and video. The filter supports longer shutter speeds for motion blur, wider apertures in bright light for shallow depth of field, and smoother video shutter control during handheld or gimbal shooting. Constructed for compact thread‑mount lenses, this model is suitable for outdoor landscape work, long‑exposure scenes, and general cinematography where variable attenuation is required.
Advantages
The adjustable design replaces multiple fixed ND filters, enabling seamless exposure changes without swapping glass. The 46 mm screw thread ensures direct attachment to compatible lenses and maintains a low profile to reduce vignetting on wide‑angle optics. The optical glass is coated to reduce reflections and preserve color neutrality, while the rotating ring provides fine, continuous adjustment between ND8 and ND128. The filter is lightweight and convenient for travel or field use, and it supports both stills and video workflows by offering predictable, repeatable light reduction.
Suitable for
 Landscape photography with long exposures
 Motion blur effects for water and traffic
 Cinematography and run‑and‑gun video where shutter control is needed
 Portraits in bright conditions to achieve shallow depth of field
 Travel and outdoor photography with compact 46 mm lenses
Key specifications
 Filter type: Variable neutral density (continuous ND)
 Adjustment range: Approximately ND8 to ND128 (≈3 to 7 stops)
 Mount/thread size: 46 mm screw‑in
 Construction: Slim profile metal ring with optical glass element
 Coating: Multi‑coated surfaces for reduced reflections and improved contrast
 Typical uses: Long exposures, aperture control in bright light, video shutter management
How to use
Screw the filter onto the front thread of a compatible 46 mm lens until it seats securely without overtightening. Rotate the outer ring to change the density setting and observe the exposure or viewfinder until the desired light reduction is achieved. When using for long exposures, mount the camera on a tripod and use cable release or self‑timer to avoid vibration. For video, adjust the ND level while monitoring the histogram or waveform to maintain correct exposure and consistent shutter speed. Store the filter in its protective case when not in use to keep the glass clean and prevent scratches.
Usage recommendations
To avoid cross‑polarization artifacts and color shifts at extreme settings, avoid using the maximum density setting unless necessary; fine‑tune exposure using aperture and ISO in combination with the variable ND. When shooting wide angles, check for vignetting after mounting the filter and use a slim profile filter or step‑up adapter if required.
