Neutral Density Filter (ND4/NDX4) for DJI Mavic Air — Greenl

Neutral Density Filter (ND4/NDX4) by Greenl is an optical filter sized for the DJI Mavic Air camera. It provides a consistent two-stop light reduction (ND4) to help control exposure in bright outdoor conditions, enabling proper shutter speeds for video and smoother motion portrayal. The filter mounts directly to the Mavic Air camera lens and is intended to reduce overexposure and allow longer effective exposures for controlled motion blur and balanced daylight images.

Advantages

The Greenl ND4/NDX4 filter offers stable and predictable light attenuation without altering color balance, helping maintain natural tones while lowering brightness. It supports improved video frame-to-frame consistency by enabling shutter speeds closer to cinematic standards at common frame rates. The physical design is compact and tailored to the Mavic Air so installation is straightforward and does not interfere with gimbal operation.

Suitable for

• Daylight aerial videography to reduce overexposure
• Outdoor photography in bright conditions
• Creating controlled motion blur for cinematic footage
• Maintaining consistent exposure when flying with varying light

Key specifications

• Optical density: ND4 (approx. 2-stop light reduction)
• Compatibility: Designed for DJI Mavic Air camera lens
• Filter type: Neutral density (non-variable)
• Effect on color: Neutral, minimal color cast when properly manufactured
• Mounting: Dedicated fit for Mavic Air camera carrier

How to use

Attach the Greenl ND4/NDX4 filter to the Mavic Air camera according to the drone’s lens cover or filter mounting procedure, ensuring the filter is clean and free of dust or fingerprints. Select shutter speed and ISO settings appropriate for your target frame rate—use a shutter speed roughly double the frame rate for natural motion blur in most video workflows—and confirm exposure via histogram or live preview. Remove the filter when flying in low-light or indoor conditions to avoid underexposure.

Usage recommendations

For best results, clean the filter surface with a microfibre cloth before each flight and store it in a protective case. Use the ND4 filter in bright daylight or when you need moderate reduction of light to reach cinematic shutter speeds; combine with proper camera settings (ISO and shutter speed) rather than relying solely on post-processing to correct exposure.
