That is almost certainly a DJI Air 3S and not something new. Sorry. Also, check out the latest drone news on DroneXL.co
I mean it is clearly an Air 3S as that is DJI latest bigger drone, and there is NO WAY EVER that you are getting a gimbal that big on a mini drone.
The camera next to it is a Sony A series, the Phone is an Oppo find 7 Ultra, its a comparative testing rig, most likely to see how the various sensors are performing vs a range of tech, smartphones do it all the time as do DSLRS, although this type of rig is newly seen from DJI using the mavic 4
It's OBVIOUSLY more than one drone CAMERA mounted on a tripod, have peoples eyes stopped working or something.....
That could be Dji's new mirrorless camera
