I'm super happy with this release.
I wanted a still camera that can also shoot proper video for a long time and I think this is it. I can surely live with 1.64x with the 17:9 ratio of the DCI 4K. Too bad no C-log but hey, there's the Vision Tech picture profils to play around with. Also, having used the A6300 and A7 series for sometimes now, I never took a single photo with them 'cause I can't stand the electronic EVF and the poor battery life. If my primary focus in live was video, I wouldn't buy a still camera that does video.
What I personnaly use for my A6300 is a 15mm rod clamp that I screw on the top or bottom of my cage. Then, I use a 18mm rod and two 8" 15mm rod handle and attach them to the rod. This way I can handle freely my camera and be very stable since I keep my two elbow agaisnt my body for stability. I can either put the handle going up or down very rapidly depending if I wanna go really high or low.
I'm only talking about the infos brand that's written on the camera, I'm not hiding the thing, just making it more "neutral". Just like if you would remove all the adds you see on a city street. ;)
I always use gaff tape to cover up the "brand" or "labels" on my equipment. Everywhere where it says Canon, Sony, 4K, blabla, etc. It helps if I want to take a picture where I need to see the camera in the mirror and it also avoid people making remarks, it's just more discreet.
A fast prime or versatile zoom lens? Think about your style of shooting and what you would need. Low light shooting? Thin depth of field? Go for a fast prime with 1.4 or 1.8 aperture. All around day shooting? That 18-105mm is surely a good choice. I own the 20mm 2.8 pancake which I quite like for the size.
That Blackmagic Video Assist 4K will be the perfect companion for the Sony users.
