The upgrade is worth it if you fly near obstacles, follow moving subjects or color-grade your footage. The Mini 4 Pro keeps the Mini 3 Pro's 1/1.3-inch, 48 MP camera, but adds omnidirectional obstacle sensing, DJI's O4 video link with 20 km range (FCC), 4K slow motion at 100 fps and 10-bit D-Log M. If you mainly fly open landscapes in daylight and don't edit color, a Mini 3 Pro you already own is still a very good drone.

What actually changes
Obstacle sensing. This is the biggest practical upgrade. The Mini 3 Pro can't see to the sides, so sideways moves and orbits around trees rely on you. The Mini 4 Pro senses in all directions in good light, which makes tracking and orbits safer. See Mini 4 Pro obstacle avoidance.
Video link. O4 is steadier behind trees and in busy areas than O3. Range itself matters less in the US, where you must keep the drone in sight, but a stronger link means fewer stutters and disconnects.
Video options. 4K at 100 fps lets you slow action down 4x without dropping to 1080p. 10-bit D-Log M holds more highlight and shadow detail for grading. The Mini 3 Pro doesn't support D-Log.
Tracking and automation. The Mini 4 Pro supports ActiveTrack with all-around sensing and waypoint flights in DJI Fly. See Mini 4 Pro waypoints.
What stays the same
- The same size sensor and pixel count, so daylight photos look similar.
- Both rotate the camera for true vertical shooting.
- Both weigh under 249 g with the standard battery, so recreational pilots don't register them with the FAA. With the larger Battery Plus, each goes over 250 g and must be registered. See FAA registration.
Who should upgrade
- Upgrade: you fly around trees and buildings, use follow modes, or edit in log.
- Keep the Mini 3 Pro: open-sky landscapes, mostly photos, standard color.
- Buying new on a budget: we don't stock the Mini 3 Pro. The Mini 3 ($461) has the same size sensor at a lower price but only downward sensing and 4K/30.
The Mini 4 Pro is FCC-authorized and sold in the US, and it gets DJI Care Refresh. Read is the Mini 4 Pro worth it or compare Mini 4 Pro vs Mini 5 Pro.
