An onboard LCD screen gives real-time aircraft data information and the detachable control sticks make the remote controller easier to store.

OcuSync 2.0 reduces the latency to 120-130 ms by improving the camera performance through the video decoding algorithm and the wireless link. Auto Focus is supported during shooting even in low light conditions. The Mavic 2 Pro supports aperture and shutter adjustment and the Mavic 2 Zoom supports zoom in/out by using the Zoom Adjustment Dial.
