Hey Mathias,
I see that you are using the ATEM Camera Control panel. I have the same panel for my 3 Broadcast G2's and am also using a Fujinon 42x lens. There is a quirk with the Camera Control panel that you might try. Do you have it set in Absolute mode or Relative mode? This can affect how quickly the iris reacts to your inputs from moving the joystick on the control panel.
The highlighted "ABS" above the White balance button in the box on the photo, need to be lit up to engage the absolute functionality.
