These cameras require using the Arducam Camera Control plugin to control focus because it's not using standard v4l drivers I think for controlling the mechanical focus which is what the camera settings plugin requires. It's similar to my older generation lower resolution arducam autofocus camera.
I have tried the Arducam Camera control plugins but they do not work with my IMX519., unable to adjust the focus.
The Camera Settings plugin does adjust the focus but I am unable to save the required setting, it resets to 0 if the system is restarted. The horizontal and vertical flip function does not work.
I don't know if the Arducam Control plugins would work with the more expensive " 64MP Hawk-eye Autofocus Camera Module for Raspberry Pi" but as it is quite a lot more expensive than the IMX519 I am not sure I want to buy one without knowing if it will work.
I don't seem to be able to find any more information about my camera being used with octoprint.
