## Summary description

Three-in-one screw-on filter by K&F for lenses with 49 mm thread, combining a variable Fader ND2–ND32 neutral density element, a circular polarizer (CPL) and a Black Diffusion 1/4 softening filter. The set reduces light intake for longer exposures or wider apertures, controls reflections and polarization, and adds subtle diffusion for portrait and cinematic effects. Suitable for landscape, portrait and long-exposure photography.

## Long description

The K&F 3-in-1 49 mm Fader ND2-32 + CPL + Black Diffusion 1/4 is a screw-on multi-function filter designed for lenses with a 49 mm thread. It integrates a variable neutral density element adjustable from ND2 to ND32, a circular polarizer (CPL) and a mild Black Diffusion 1/4 softening filter in a single compact unit. This combination reduces incoming light for longer exposures or wider apertures, controls reflections and improves color saturation with the CPL, and adds subtle diffusion to soften highlights and reduce micro-contrast for portrait and cinematic looks.
Advantages
This three-in-one filter saves time and space by combining neutral density, polarizing and diffusion effects without the need to stack multiple separate filters. The variable ND provides flexible light reduction for extended exposures and shallow depth-of-field control, while the CPL helps eliminate unwanted reflections from non-metallic surfaces and increases color saturation in skies and foliage. The Black Diffusion 1/4 imparts a gentle softening effect that smooths skin tones and reduces contrast in specular highlights, useful for portraits and video work.
Suitable for
Landscape photography requiring polarization and controlled exposure
Portraits where subtle diffusion and skin softening are desired
Long-exposure photography of water, clouds or urban scenes
Cinematic and video shoots needing gentle bloom and reduced contrast
Outdoor photography where glare and reflections must be minimized
Key specifications
Mount thread diameter: 49 mm for direct screw-on attachment to compatible lenses
Neutral density range: variable from approximately 1 stop (ND2) to 5 stops (ND32)
Polarizer type: circular polarizer (CPL) for use with modern autofocus and metering systems
Diffusion strength: Black Diffusion 1/4 for mild softening and highlight bloom
Construction: slim filter ring profile to reduce vignetting on wide-angle lenses
Finish: multi-coated glass elements to minimize flare and maintain image clarity
How to use
Screw the filter onto the front of any lens with a 49 mm filter thread until it is secure but not overtightened. Rotate the ND control to adjust light reduction between ND2 and ND32 while observing exposure changes in the camera or using a light meter. Turn the CPL ring to orient the polarizer and reduce reflections or enhance sky contrast; the effect is most visible at a 90-degree angle to the sun. Use the diffusion element to soften highlights and reduce micro-contrast; avoid excessive diffusion if maximum sharpness is required. When combining effects, verify metering and focus as the polarizer and ND will affect exposure and autofocus performance.
Usage recommendations
For best results in landscape photography, set the CPL to maximize sky contrast before dialing in the ND value for the desired shutter speed. In portrait sessions, keep the diffusion mild and check skin tones at different apertures to balance softness with detail retention. When shooting long exposures, use a tripod and live-view or mirror-lockup where available to minimize camera movement; bracket exposures if uncertain about ND settings.
