## Summary description

Accessory filter set for DJI Osmo Action cameras, compatible with Action 3, 4 and 5 Pro.

Mounts to the camera lens to support outdoor and cinematic shooting.

## Long description

The K&F 3-in-1 Filter Set PL + ND2-32 + Black Diffusion 1/4 for DJI Osmo Action 3/4/5 Pro is an accessory kit designed to expand the photographic control and creative options of compatible Action cameras. The set contains a polarizing (PL) filter to reduce reflections and deepen color saturation, a variable neutral density filter covering ND2 to ND32 for flexible exposure control and motion blur management, and a Black Diffusion 1/4 filter that produces a gentle softening effect and subtle highlight bloom. Each filter mounts directly to the camera lens area to support outdoor shooting and cinematic capture workflows.
Advantages
The polarizing filter improves clarity by minimizing surface reflections on water, glass and wet surfaces while enhancing sky contrast and color fidelity. The variable ND2–32 filter enables seamless control over light intake without changing lenses, allowing slower shutter speeds for smoother motion or wider apertures in bright conditions. The Black Diffusion 1/4 filter creates a mild diffusion effect that reduces contrast and adds a soft glow to bright highlights, useful for portrait-style footage and cinematic looks. Together, these filters provide a compact, interoperable solution for photographers and videographers working with DJI Osmo Action 3/4/5 Pro cameras.
Suitable for
Outdoor landscape and travel videography
Action sports footage in bright sunlight
Cinematic B-roll and interview footage outdoors
Beach, water and reflective-surface shooting
Low-light motion control where longer exposures are required
Key specifications
Filter types: Polarizer (PL), Variable Neutral Density (ND2–ND32), Black Diffusion 1/4
Compatible models: Designed for mounting on DJI Osmo Action 3, 4 and 5 Pro cameras
ND range: variable from approximately 1 stop (ND2) to 5 stops (ND32)
Diffusion strength: 1/4 stop equivalent softening with highlight bloom
Mounting: dedicated mount for action camera lens area; low-profile design to minimize vignetting
How to use
Attach the required filter to the camera lens area according to the mount design; ensure the filter is seated securely before recording. For reducing glare and increasing color saturation use the PL filter and rotate it until the desired effect on reflections and sky contrast is visible. For controlling exposure and motion blur in bright conditions use the variable ND filter and adjust its ring to obtain the required stops of light reduction between ND2 and ND32. Use the Black Diffusion 1/4 filter when a subtle softening of highlights and mild bloom are desired; this filter is suitable for close-up portraits or to reduce the clinical sharpness of high-contrast scenes. When switching filters, power off the camera or stabilize it to avoid touching the sensor area and clean filter surfaces with a microfiber cloth to prevent dust and smudges.
Usage recommendations
For optimal results, combine the PL filter with the ND filter in high-glare outdoor situations to both control exposure and suppress reflections. When using the ND2–32 filter for slow-shutter effects on moving subjects, monitor shutter speed and frame rate to avoid excessive motion blur. Use the Black Diffusion 1/4 sparingly in very bright highlights to maintain detail while achieving a cinematic bloom; always check framing for potential vignetting when stacking multiple filters.
