Camera Butter DJI O4 Pro Air Unit ND Filters and Lens Protectors

No, these filters are precision-engineered exclusively for the DJI O4 Pro Air Unit. The 20.6mm diameter and silicone retention system are specific to this unit's dimensions and will not fit other models.

The filters are designed to be mounted in either direction. By reversing the orientation, you can achieve a tighter, more compact profile, which is particularly useful for FPV builds where space is limited and every millimeter counts.

Yes, the nano-coating is highly effective at repelling moisture, oil, and dust. It prevents water droplets from beading on the lens during damp flights, which helps maintain image clarity and makes cleaning the glass significantly easier after landing.

Corning Gorilla Glass offers significantly higher impact and scratch resistance than standard optical glass. While no filter is indestructible, this material is specifically chosen to withstand the debris and minor impacts common in FPV flying, providing a much higher level of protection for your camera lens.

The 7-layer anti-reflective coating is designed to minimize glare and internal reflections, ensuring your footage remains sharp and contrast-rich. Because they are high-quality neutral density filters, they are color-neutral and should not introduce unwanted color shifts into your footage.

Each filter weighs only 1.2 grams. This negligible weight increase ensures that your flight performance, center of gravity, and battery efficiency remain virtually unaffected.
