The gimbal is not supplied with a suitable carrying case as standard. However, there are separate carrying cases that have been specially developed for the DJI RS 4 and can be purchased separately.

No, unfortunately not. You have to buy this for approx. 75.

You can take vertical shots with the standard RS 4 without the need for a special plate from the combo. The RS 4 supports native vertical shots, which means that you simply have to turn the camera round and rebalance it to take vertical shots.

I'm not sure whether the DJI RS 4 Mini gimbal is compatible with Sony A7 and A9 cameras. To check compatibility, I recommend that you consult the official compatibility list on the DJI website. This will tell you whether these models are supported by the gimbal.

The RS 4 is sufficient up to a payload capacity of 3 kg. If the camera and lens together are heavier than 3 kg, then the RS 4 Pro is the right choice. The Blackmagic PYXIS 6K is 1.5 kg, the Blackmagic Cinema Camera 6K is 1.1 kg, so the RS 4 should be enough. The Pro version alone is already heavier and you have to carry that in addition to the camera and lens.

No is not included. Only gimbal with very few accessories, no bag either. Makes transport very cumbersome at times. If you really need the motor, it would be the Pro Combo: DJI RS 4 Pro Combo (system camera, SLR camera, 4.50 kg) Absolutely worth it in my opinion. The Raveneye system is also very useful, depending on the camera, as you can then adjust the camera settings on your mobile without having to block the gimbal every time. Object tracking (only with Raveneye) also works excellently with slow movements without a lot of foreground.
