## Long description

The Neutral Density Graduated Variable Filter K&F 52mm Fader Gray ND2–ND400 is an adjustable screw-in gray filter for 52mm lenses that provides continuous light reduction from about 1 to 9 stops. It allows precise control of exposure to achieve long exposures, controlled motion blur, and the ability to use wider apertures under bright conditions without overexposure. The filter is designed for photographers who need a compact, flexible solution for managing light during landscape, architecture and creative shoots.
Advantages
This variable ND filter offers a smooth, stepless transition across a wide attenuation range, enabling fine exposure adjustments without changing multiple fixed filters. The screw-in design ensures simple attachment to any lens with a 52mm thread. Constructed to preserve color balance and sharpness, it reduces the need for post-processing to correct exposure while providing reliable control over shutter speed and aperture in varied lighting conditions.
Suitable for
Landscape photography requiring long exposures and controlled highlights
Architectural and cityscape shots where balanced exposure is needed
Creative motion blur and water smoothing effects
Portraits or shallow-depth images in bright outdoor light when using wide apertures
Key specifications
Filter type: Variable neutral density (gray) graduated
Thread size: 52 mm screw-in mount
Light reduction range: Approximately 1 to 9 stops (ND2–ND400 equivalent)
Control: Continuous (stepless) adjustment
Primary effect: Attenuates light while maintaining color neutrality and image sharpness
How to use
Screw the filter onto the front of any lens with a 52mm thread and rotate the adjustable element to set the desired density. For long exposures, increase attenuation until the exposure meter indicates the target shutter speed, or use a camera in manual or shutter-priority mode to preview effects. When creating motion blur, adjust density to allow slower shutter speeds while maintaining correct exposure; for shallow depth of field in bright light, reduce light enough to open the aperture to the preferred value. Check through the viewfinder or live view to ensure framing and exposure, and avoid extreme rotation settings that may introduce uneven vignetting on wide-angle lenses.
Usage recommendations
Use a tripod for long exposures and bracket densities when testing new scenes. When shooting wide-angle lenses, be cautious of potential cross-polarization or uneven darkening at extreme settings; step back density if unwanted artifacts appear. Clean the filter surfaces before use and store in a protective case to preserve optical quality.
