AxisFlying ND Filter Set for DJI O4 Air Unit (ND4/8/16/32)

The AxisFlying ND Filter Set for the DJI O4 Air Unit gives FPV pilots precise control over camera shutter speeds in bright environments, helping eliminate jello and achieve smooth cinematic motion blur. Custom-machined for the O4 camera module, this four-piece pack covers lighting conditions ranging from overcast mornings to glaring mid-day sun, making it a necessary addition for HD cinewhoop, freestyle, and commercial heavy-lift rigs.

• Ultra-lightweight aluminium alloy frames prevent unwanted resonance and keep front-end weight to an absolute minimum.
• Press-fit mounting design allows fast, tool-free filter swaps in the field between packs.

To follow the 180-degree shutter rule (locking your shutter speed at exactly double your frame rate, e.g., 1/120s for 60fps), use the ND32 for bright mid-day sunlight, scaling down to the ND4 or ND8 for golden-hour flying.
