Dragonframe only has direct support for the first two BMD cameras: the original “Cinema Camera” and the “Production Camera 4K”.
Why? Because these camera have Thunderbolt output and provide a way for Dragonframe to directly retrieve high-resolution streams.
Newer cameras do not have the same direct control capabilities.
You can use newer Blackmagic cameras the same way you can use other HDMI sources: by using a Blackmagic capture device to take the HDMI output of the camera and bring it into the computer. This will only bring HDMI input into the computer. It does not capture RAW or DNG images.
In most situations, it is simpler and yields better results to use a supported still camera.
