Q: 8. Can the camera be mounted in the portrait position? Can not seem to tell in the photos. Thanks!

A: If you're using a telephoto lens where the foot can be rotated then yes you can! Otherwise you'd need an L bracket and then an arca quick release adapter like this: https://bhpho.to/3kVPpGI . To set this up you'd need a base arca plate that would go into the gimbal head. That plate would screw into the bottom of the quick release clamp. Finally the L-bracket would slide into the quick release clamp.
