Today we have the full specs of that the Mavic Air 2 can do. I believe this is somewhat a response to Skydio R2 with the new FocusTrack which is said to be much more effective than the Mavic 2 active track 2.0. From the demo we can see that the Mavic Air 2 can navigate through a forest trail avoiding the trees and etc. See the video here

Is it worth for owners of Mavic 2 Pro / Zoom to buy the Mavic Air 2?

Well, I must say I was really tempted by the 4K60p video and the 48MP camera. But without the ability to adjust aperture, to do dolly zoom is a huge sacrifice for me. Also, a 1″ sensor vs a 1/2″ sensor is also a big sacrifice for night video. You notice there is no night video of the Mavic Air 2 produced by DJI, except for the hyper-lapse video which is a series of still photos and not video. HDR Video is a plus point if the user wants to use the footage straight out of the drone. However, for most production house they rather shot in D-log and do color grading in post-production.

There are definitely some nice cool features and a huge upgrade from the first Mavic Air, but compared to Mavic 2, it may not be a real upgrade in some sense for the pro videographer who wants more control. But for those who want to have their first UAV, the Mavic Air 2 is a great choice.
