Dear!I have been used Black Magic with Ronin S and Sigma Lens, but i dont know how to use Focus with Ronin S, So can you tell me how to use!
Thanks alot!

Hi there, Balck Magic is not in the compatible list at the moment, the compatibility cannot be fully ensured.
But if you would like to use the Focus function, it is recommended to use the Focus Motor, which is used with the Ronin-S Focus Wheel to control the focus, iris, and zoom.
