Follow focus wheel Zhiyun Crane 3s destroys focus BMPCC4K

PostTue Aug 03, 2021 12:07 am

Hi everyone, I hope I'm not the only one with this issue.
I have my BMPCC 4K successfully installed on the Zhiyun Crane 3s, choosing 'CSS' as the camera type gives me control over record start/stop, aperture, shutter speed and ISO, but when I do as much as touch the follow focus knob on the Zhiyun gimbal, it immediately pulls the internal (electronic) focus to the minimum distance. Turning the wheel either way makes no difference, focus seems to lock up.
Now when I have a servo attached this will react to the turning of the followfocus wheel but as you can imagine any form of proper focusing will be obstructed through the electronic, USB way.

How can I get this to work? It seemed to work for a brief moment, crazy enough. But ceased in the blink of an eye. Any advise is strongly appreciated.

Bump... would be nice to get some kind of answer though. Wouldn't know the use of this forum otherwise.

You can only get an answer if someone is using the very same setup.
Why do you think other users here "owe" you an answer is beyond me.

Have you contacted Zhiyun? It's their product behaving strangely.
Maybe they have a firmware update for the Crane 3s?
What's the firmware of your camera?

BTW, I am using a DJI RS2 with the PCC4k and focus works great in that combination.
Saying "Thx for help!" is not a crime.
