Hi Laird

How come with the new firmware updates (CineRT/Arri) in focus tracking mode that the focus is thrown to infinity when CineRT looses its readings?

It renders the focus tracking mode useless IMO as the motor will pull the focus back and forth from reading to infinity.

This wasn't the case before the firmware upgrades and focus tracking was really useful especially between takes to relax the wrist 😊.

I can't say if it's a Arri issue or a CineRT issue. But the issue was there even before the new firmware 24.06.

Tbh I'm considering downgrading again to hopefully get this functionality back 😄
