GH5 Focus via USB-C
  • Hi,

    i just wondered if it is possible to focus on the GH5 via USB-C? Either with a bought device or by building the controller by yourself. Since the Ronin S can do it i am quiet sure it should also be possible for others?

    Thank you!

  • In theory, it shouldn't be too hard to figure out how to do it as long as the communication isn't encrypted.

    I haven't used this software, but it looks like it would do what is needed: https://freeusbanalyzer.com/

    Run the software, plug the camera into the computer, load the Panasonic control app that can control the camera, and adjust focus through software. From that, you should be able to see the commands sent by the software to initialize the camera and to adjust focus.

    With that, it should be pretty easy to make a raspberry pi zero controller with a couple of buttons and a small battery.

    Otherwise, if you're willing to use EF lenses, you could use something like the Aputure DEC Lens Regain which lets you control the lens focus wirelessly.

  • @eatstoomuchjam Sounds great, i will definitly try this as soon as i have the time for it. Will keep you informed in case you are interested. I'm surprised that nobody else tried this before (at least i hadn't been able to find somebody writing about it)
