Follow/Autofocus for Broadcast G2 and Fujinon LA16x8brm

Hey Guys,
just a simple question: As i understood correct the Broadcast G2 has a autofocus in combination with the fujinon LA16x8BRM, is that correct?

Is there also a possibility of follow focus as you know it from for example a canon r5 or do i have to set the back focus lens flange new for every shot?

So, after i calibrated everything and i hit the "FOCUS" button on the camera, the thing i focused is sharp for 1 second and then it the cam looses the focus. So if if repeatedly press the focus button it sometimes gets sharp, sometimes not but when i let go, the focus is gone.

I'm a little bit confused right now and couldn't find any helping material in the web nor the manual.

I made a short video -> https://www.youtube.com/shorts/B2DDAe9LLJs

The Camera was deliverd today with Firmware 8.5.1 already installed.

There is no Autofocus on the Ursa Broadcast G2, nor is there on the Fujinon LA16x8BRM bundled lens.

Perhaps confusingly, you can tap-hold on the G2's flip-out screen to initialise focus (which as you've found out, can be a bit hit and miss). But that's it. Focus is manual from thereon.

Here's a video that explains setting up back focus on the Fujinon LA16. Ignore the thumbnail saying LA12.

Okay so i could achieve autofokus with the dji focus pro right?
