K&F ND Filter Set 4-in-1 (ND8, ND16, ND32, ND64) for DJI Osmo Action 4

K&F ND Filter Set 4-in-1 (ND8, ND16, ND32, ND64) for DJI Osmo Action 4 is a compact neutral density filter kit designed to control exposure and motion rendering when shooting with the Osmo Action 4. The set contains four graduated-strength ND filters that reduce the amount of light entering the camera lens, allowing for longer shutter speeds and more accurate exposure in bright conditions. These filters are intended for screw-on or magnetic attachment systems compatible with the camera, delivering smoother motion blur, reduced highlights, and improved control over depth of field during action video and still photography.

Advantages

The K&F 4-in-1 ND kit provides predictable light reduction across four stops of density options so you can select the appropriate filter for varying lighting situations. Filters are optically designed to minimize color cast and preserve image sharpness, helping maintain natural color rendition while reducing exposure. The compact set is convenient for mobile action shooting and allows quick swapping of filters to match changing light. Suitable for use with the DJI Osmo Action 4, the filters support both slower shutter speeds for motion blur and wider apertures for selective focus when conditions permit.

Suitable for

• Action video recording in bright daylight
• Capturing motion blur for dynamic scenes
• Maintaining correct exposure during outdoor photography
• Creating shallow depth-of-field effects in well-lit environments
• Time-lapse sequences with controlled exposure

Key specifications

• Filter types: ND8, ND16, ND32, ND64 (progressive light reduction options)
• Optical material: multi-coated glass for reduced reflections and improved light transmission
• Compatibility: designed for mechanical attachment compatible with DJI Osmo Action 4 filter/thread or magnetic mount systems
• Finish: anti-reflective coatings to limit flare and ghosting
• Form factor: compact, lightweight design suitable for action cameras

How to use

Choose the ND filter strength that matches ambient light and the desired shutter speed: ND8 for moderate reduction, ND16 for stronger light control, ND32 and ND64 for very bright conditions or slower shutter effects. Attach the selected filter to the DJI Osmo Action 4 using the compatible screw-on or magnetic mount. Verify secure fit and frame the shot in a preview mode; adjust exposure settings on the camera if necessary to achieve the intended shutter speed or aperture. Swap filters as lighting changes and store unused filters in a protective case to avoid scratches.

Usage recommendations

Use lower-density ND filters (ND8/ND16) for subtle motion blur or when light is moderately bright; switch to ND32 or ND64 in intense sunlight or when you need longer shutter durations. Always check white balance after attaching an ND filter and compensate exposure in manual or shutter-priority modes for consistent results. Clean filters with a soft microfiber cloth and lens-safe cleaner to maintain optical performance.
