There are multiple steps involved in getting the Ronin RSC 2 to work properly.
Due to the pandemic, we have to figure this all out online, which is not easy.
First step is getting your camera to balance on the gimbal. Balancing is essential and note that not all lenses balance properly.
DJI provided a list of supported lenses for my camera, the BMPCC4K so I bought one.
Find a tutorial video about balancing for your camera and a similar lens to yours. Once the camera with lens balances, then what?
Then you need to calibrate the camera, which fine tunes the setup:

After you watch the second video,
then you can start shooting.
Patience required.
