RunCam Curved Precision ND Filter Set for DJI O4 Wide Air Unit (UV/ND8/ND16/ND32)
Designed specifically for the DJI O4 Wide Air Unit, the RunCam Curved Precision ND Filter Set provides a perfect optical fit for the protruding wide-angle lens. Unlike flat filters, the curved optical design maintains the full 159° ultra-wide field of view, helping to eliminate vignetting while delivering consistent edge-to-edge image quality.
Manufactured from precision-coated ultra-clear optical resin, each filter offers excellent light transmission together with reliable impact resistance, making it well suited to demanding FPV flights. The dual-lock mounting system keeps the filter securely in place, even during high-speed manoeuvres, rapid dives, and high-vibration flights, giving you the confidence to fly without worrying about the filter coming loose.
The set includes four professional-grade filters – UV, ND8, ND16, and ND32 – allowing you to adapt quickly to changing lighting conditions and achieve smoother, more cinematic footage with the correct shutter speed.
Weighing just 0.36g, the lightweight design has minimal impact on your aircraft while providing the flexibility needed for a wide range of flying environments.
Whether you’re capturing bright midday landscapes or flying in variable lighting conditions, the RunCam Curved Precision ND Filter Set is an ideal upgrade for pilots looking to get the very best video performance from the DJI O4 Wide Air Unit.
