## Summary description

3-in-1 hybrid photographic filter for 49 mm lenses by K&F combining a variable neutral density (Fader ND2–32), circular polarizer (CPL) and Black Diffusion 1/4. Designed to control exposure, reduce reflections and soften highlights for portrait and landscape photography. Screws onto 49mm filter threads and suits practical on-camera use for creative control.

## Long description

The K&F 49 mm Fader ND2-32 + CPL + Black Diffusion 1/4 is a compact 3-in-1 hybrid photographic filter that combines a variable neutral density (ND) element, a circular polarizer and a subtle diffusion layer. It screws onto lenses with a 49 mm filter thread to provide exposure control, polarization for reduced reflections and increased color saturation, and a gentle highlight diffusion useful in portrait and landscape work. The integrated design saves time on set and avoids multiple stacked filters while enabling gradual adjustment of light and reflections.
Advantages
This combined filter offers adjustable light reduction from approximately 1 to 5 stops via the Fader ND2–32 function, allowing longer exposures or wider apertures in bright conditions without changing camera settings drastically. The built-in CPL reduces glare from non-metallic surfaces and improves color contrast, while the Black Diffusion 1/4 layer subtly softens highlights and skin textures to produce a more film-like rendering. The single-ring mounting design ensures straightforward attachment to 49 mm threads and compact on-lens profile for practical use in the field.
Suitable for
Landscape photography requiring longer exposures and enhanced sky saturation
Portraits where gentle highlight diffusion and softer skin rendering are desired
Outdoor and travel photography where reflection control and compact gear are important
Videography that benefits from controlled exposure and reduced specular highlights
Key specifications
Filter type: 3-in-1 hybrid combining variable Neutral Density (ND), Circular Polarizer (CPL) and Black Diffusion 1/4
Variable ND range: ND2 to ND32 (approximately 1 to 5 stops of light reduction)
Mount diameter: 49 mm screw-on
Diffusion strength: 1/4 (subtle softening of highlights and textures)
Material: multi-coated optical glass elements with metal frame
How to use
Screw the filter onto the lens front using the 49 mm filter thread, ensuring it is seated evenly. Rotate the ND control to adjust the amount of light reduction until the desired exposure or motion blur is achieved; then rotate the CPL element to minimize reflections and enhance contrast in skies, foliage, or water. Observe the image in the viewfinder or on the camera monitor while making adjustments. Combine ND and CPL settings as needed for balanced exposure and reduced glare. Remove the filter when not required to restore maximum sharpness and prevent any unintended diffusion effects.
Usage recommendations
Use the Fader ND2–32 to extend shutter times for motion effects or to enable wider apertures in bright light, and fine-tune reflections with the CPL rotation. Apply the Black Diffusion 1/4 for portraits or highlights that would otherwise appear harsh; check focus and contrast after fitting the filter, and avoid stacking additional dense filters to prevent vignetting on wide-angle lenses.
