Focus demand issues

Hello,

I have a BMD focus demand connected to Studio 4k Pro, and sometimes it has an erratic behavior, that when I touch the demand the focus change abruptly and gets the image not focused.

I tested with both Panasonic PZ lens and both have the same behavior

The camera was updated to the last firmware version

I have been having a similar problem with my Micro studio 4k G2 cameras. I also have the Lumix 45-175 Power zoom lens with a zoom and focus demand and like you said, it glitches out at random times and needs to be turned all the way one direction before you can rgain control of the focus. I just started researching this problem, when I found this thread. Has anyone heard of any other solutions?

We're having the same problem (BM Studio 4k pro + Lumix 45-175 PZ + BM zoom demand).

I'd be interested to know if others have also found / managed to resolve this please?

Thanks

I'm having the same problem with both Zoom and Focus demand just stop working
