## Summary description

Adjustable K&F 55mm neutral density (ND) variable filter KF X Fader in gray with attenuation range ND8–ND128. Designed for 55 mm lens threads, this variable ND reduces light transmission continuously to allow longer exposures, wider apertures in bright conditions, and motion blur control. Suitable for landscape, long-exposure, and videography applications requiring exposure control.

## Long description

The Neutral Density Variable Filter K&F 55mm KF X Fader Gray ND8–ND128 is a screw-on adjustable neutral density filter for lenses with a 55 mm thread. It provides continuous attenuation from approximately 3 to 7 stops (ND8 to ND128), allowing precise control of light entering the lens. The filter is designed to enable longer exposures, wider apertures in bright conditions, and smoother motion rendering for both still photography and video work without changing camera exposure settings.
Advantages
This variable ND filter offers a smooth, continuously adjustable range of light reduction between ND8 and ND128, eliminating the need to carry multiple fixed ND filters. It is compatible with lenses that accept 55 mm screw-in filters, providing a compact and lightweight solution for exposure control. The gray neutral density coating maintains natural color balance while reducing light transmission, and the threaded design ensures secure mounting and straightforward operation.
Suitable for
 Landscape photography with long exposures to smooth water and cloud movement
 Portraits or shallow depth-of-field shooting in bright light using wider apertures
 Video and time-lapse work requiring consistent exposure while controlling motion blur
 Travel and outdoor shoots where compact, versatile exposure control is needed
Key specifications
 Filter type: Variable neutral density (gray)
 Attachment: 55 mm screw-in thread
 Attenuation range: ND8 to ND128 (approx. 3 to 7 stops)
 Adjustability: Continuous variable density via rotating ring
 Optical effect: Reduces light transmission while preserving color neutrality
How to use
Mount the filter onto a lens with a 55 mm front thread by screwing it on until snug. Rotate the outer ring to vary the density and observe exposure/readout on your camera or use a light meter to achieve the desired shutter speed or aperture. When using long exposures, stabilize the camera on a tripod and use mirror lock-up or electronic front curtain shutter if available to reduce vibrations. For video, adjust the filter gradually to avoid sudden exposure shifts during recording.
Usage recommendations
To minimize optical artifacts such as vignetting or cross-polarization at extreme settings, avoid stacking multiple dense filters and stay within the mid-range adjustments when possible. Clean the filter surfaces with a lint-free cloth and appropriate lens solution before critical shoots, and store the filter in its case when not in use.
