One thing about the form factor.
It's not going to be replacing the GH5 anytime soon as a walk around camera.
Example, I own and still love my 5D Mark III, which does great video with ML as well as outstanding stills.
But I don't carry it around for everyday stuff. For that I have a Fuji X100F and a Sony A7S.
The 5D is just simply too big, unless I am on a specific assignment.
This new BM camera feels the same.
Great for dedicated video, but not your hang around the neck, even at parties type thing.
In fact it's even a little bigger than the 5D.
So great for dedicated video work, but let's keep things in perspective. For the pocket it ain't.
