In the Mavic 2 FAQ there is the question:

• Why can't the Mavic 2's gimbal shoot vertically as the Mavic Pro does?
• The Mavic 2's gimbal structure is optimized for increased stiffness, meaning that the camera is unable to rotate the full 90° needed to shoot vertically. However, you can choose the Vertical Mode in Panorama to get a stitched vertical photo.
  

So it does not do the Portrait mode. Ok for me.  But does the gimbal can aim the ground, I mean 90º ?
In the drone comparison there is:


Controllable Range
Mavic 2 Tilt: -90–30°    Mavic 1 Tilt: -90° to +30°  


Does Mavic 2 goes only till -30º, or this is not a minus sign, but a "to" sign ?


Thanks

Hi Emilio, sorry for the confusion, it means "to", the controllable range is -90° to +30°. Hope it helps.
