No offense, but I think that if you are serious about video to the point that EM1II is not enough and you need a GH5, then you should seriously consider manual focusing (so DFD or not DFD isn't a relevant issue) and lenses especially designed for video...

I already manual focus for video and own a nice set of primes for it.

The reason the EM1 mk2 isn't under consideration is that the while the advertising states a bit rate of just under 237 Mbps it is actually variable and most of the time it spits out around 24Mbps which at 4:2:0 means that the files are brittle and can be difficult to grade.

I would like to maintain a hybrid workflow where one camera can do both stills and video, but it is now looking more likely I'll end up springing for something like a Canon C100. Shame really I had high hopes for the gh5 but the AF seems half baked.

It looks like the C100 has a max bit rate of 24 Mbps.  I recall from past reviews that the video quality is equivalent to my 70d, which I'd rate as crappy (at least as far as detail or ability to grade).  Perhaps I'm wrong.  But you can get clean HDMI out and record on an $400 1080p Atomos.  I'd expect that would look pretty darn good.  But at $3400 for C100 with Dual Pixel and an Atomos, that is quite a bit more than the GH5, and you loose high speed recording and the ability pan and zoom in post with 4k.  And you might need new lenses?

It really comes down to how much you need continuous autofocus.  And note that even Canon Dual Pixel isn't perfect - it will lose focus sometimes.  So you'll likely want to continue to use manual focus on stationary subjects.
