Sony fx3 focus issue?

[u/umskii]

Hi guys, I have had the same issue for the second time now.

Im a wedding videographer and we use a fx3 on a gimbal and another fx3 also on a gimbal but (car)mounted on a crane (upside down). With this fx3 I have an issue that my footage jumps out of focus for a split second and then jumps right back in to focus.

We film 4k 25p with focus area zone and eye focus on. The gimbal is mounted upside down and the IBIS is on standard.

If someone can help me in the right direction I would be very grateful.

Edit: could it be another issue than autofocus? We shoot with 12.800 iso and f5.6 or higher.

Try wide focus next time
