Neutral Density Adjustable Fader Filter (ND2–32) K&F for DJI Osmo Action 3/4/5/Pro

The Neutral Density Adjustable Fader Filter (ND2–32) by K&F is designed for DJI Osmo Action 3, 4, 5 and Pro cameras to provide variable light reduction in bright shooting conditions. The filter covers a range from ND2 to ND32, allowing continuous control over exposure and motion blur without changing fixed-density filters. It attaches to compatible Osmo Action housings or lens threads and is intended for outdoor video, action footage, time-lapse and long-exposure photography where controlled light intake is required.

Advantages

The adjustable fader design replaces the need to carry multiple fixed ND filters, offering smooth transition across densities to achieve precise exposure and shutter speed control. Neutral color balance minimizes color cast so that white balance adjustments remain straightforward. The compact, lightweight construction is tailored to small action camera form factors and preserves framing and autofocus behavior while helping to reduce glare and overexposure in bright outdoor scenes.

Suitable for

• Action and sports video recording in bright daylight
• Outdoor time-lapse sequences with controlled exposure
• Long-exposure shots to create motion blur effects
• Situations requiring quick adjustment of light reduction without swapping filters

Key specifications

• Variable light reduction range: ND2 to ND32
• Designed for: DJI Osmo Action 3 / 4 / 5 / Pro compatibility (mounts to compatible housings or lens threads)
• Filter type: adjustable (fader) neutral density
• Effect: continuous attenuation for exposure and motion blur control
• Construction: lightweight, low-profile design for action cameras
• Optical performance: neutral color balance to minimize cast

How to use

Mount the K&F adjustable ND fader to a compatible Osmo Action housing or screw it onto the camera lens thread if your model and housing support threaded filters. Rotate the outer ring to vary the density between ND2 and ND32 until the desired exposure or motion blur is achieved. Check camera exposure meters or use manual exposure/shutter speed settings to fine-tune results; when shooting video, adjust shutter speed according to frame rate to control natural motion blur. Inspect the image for any vignetting or color shift and make minor white balance corrections if necessary.

Usage recommendations

Use the filter when shooting in bright daylight or reflective environments to prevent overexposure and to allow lower shutter speeds for smoother motion portrayal. For time-lapse and long-exposure scenes, set the density to achieve the target exposure, and secure the camera to a stable mount to avoid unintended camera movement.
