Yeah most definitely, I am thinking of upgrading to the GH5s in the new year if the Lumix S1 ends up getting released, as much as I love the GH5, the GH5s is the king of videography right now once you start using speedboosters (which I already do). Such a fantastic annoyance to have, because either way you end up with a superb camera!
Thanks for pointing this out. I have had my reservations about the Panasonic AF system, if it wasn't a flawed system, I'd have snatched up a GH5s by now as it's the one to beat on everything else
You need good autofocus then, in that case don't go with Panasonic at this point in time, even though I personally use a GH5 I can't recommend them for anyone who needs tip top autofocus. Sony won't be beaten on that front.
Also looking for something to both take quality pictures and 4k video. Next years models look quite interesting.
