You are right ceteris paribus, but the bit depth statement and the visual comparison ignores the role of bitrate (that is, you have compared different bit depths for highly compressed clips (I assume)). The test posted above shows us that bitrate matters also, and that it matters more. Remove the high compression, and the difference by bit depth shrinks almost to invisibility. So you are correct, it is just that it turns out something is even more important than bit depth (they interact). That is, when you use 8 bits but do not highly compress you get much less banding. I have heard this before; I am not claiming the bitrate effect is correct other than interpreting what the poster showed (and I do not see anything wrong with his test).

Remember, S-LOG should be exposed differently to Cine 2 - at least 1 stop to the right.
That's why the Sony shots look too dark in Phil's test. But we'll forgive him. He has the flu!
What strikes me from that one is the colour on the GH5S is way better than Sony's default settings. The typical zombie yellow is there on the A7S II especially. That's what EOSHD Pro Color is for, as it fixes it.

Where did you hear this? According to Panasonic the sensor in the GH5s is a Panasonic design. Sony had nothing to do with it.

Mostly handheld, without ibis. Lenses from 12mm to 35mm on the pocket camera.
 

While IBIS is great, I agree with Axel.
In my short video life, I always shot with cameras that didn't feature IBIS and that wasn't a problem.
Something like this http://cn.aputure.com/V-Rig-MR-V1 is cheap, light and practical to carry around.
If I am to do a shot with a long lens, I know I will need a tripod.
But to each his own. I just never was someone who filmed with just his hands, always got some kind of support to minimize extra shakiness.
 
 

Yes, it’s very interesting. I think there is a lot of potential to this camera. If I was in the position that I could only have one, I would handily choose the GH5s over the GH5. Not that I ever look at my GH5 and think it’s not great, but I am constantly away of it’s limitations. I will not have my GH5s until next week Wednesday. I am looking forward to this camera.

I have also done some tests. However, I found that Canon L glass works quite well while shooting video as long as you are using the Metabones adapter.
 
 

If Mavic Pro 2 comes with the Phantom camera that would be awesome. Last year at a drone conference I told a DJI VP why on earth are you not releasing either a Phantom that folds like a Mavic or a bigger Mavic with Phantom's camera. 
I told him we are tons of videographers and photographers out there who need maximum portability (in my case mountain trekking for days) combined with maximum image quality. 

The Phantom form factor did not evolve since version 1, many years ago. It is not relevant anymore. 
He answered "we are not sure there is a market demand for that". I told him well who on earth would prefer the actual P4 Pro versus the same drone but completely foldable? 
Mavic Pro 2 with 1" camera and 4K60P is an INSTAN buy for me. However I am very afraid of this: 
They will release a Mavic Pro 2 with all advancements of Mavic Air (more avoidance sensor, gesture control, ...) + keep the better range and flight time + bump the camera to 100mbps and 4K60P which I do not care. Give me 1". Even if a bit bigger. There is a world of difference between an Mavic Pro and Phantom today in size. 
 

Since no doubt many here are interested in this camera I thought it might be nice to have a thread where we could post footage. I’ll get things started with the below submission. It’s not my work... but I did stay at a Holiday Inn express once 
 

Yeah when physics pops up with small sensor sizes and slower apertures... reality acts like a bitch in a soap opera without mercy ;-)

A key issue in this is what the uploaded HDR video looks like on YouTube when viewers do not have HDR capability. 
The good news is that YouTube converts the HDR video, if it has the correct metadata, to an SDR version and shows the SDR version if it detects no ability to display the HDR video correctly. That is, if the video is HLG and the display cannot work with HLG videos then it plays the SDR version.
And, in my experience, the SDR version of HLG videos converted by YouTube look good.
The downside is confusion on the part of viewers whether they are seeing HDR or SDR. The uploader usually labels the video as HDR, so many viewers might think they are viewing in HDR when they are not. And this could be true even if they have a real HDR-capable display but, say, one that does not do HLG.
All in all, if uploading to YouTube is what you do I am tending to go with the idea to always create and upload HDR videos.
 

Lol. Allow me to disagree.
Sigma make great lenses and they do not make you pay twice what it worth like everyone else. They make for great videos and pictures. That's what I want.

Different markets really... A7r iii is double the price of the gh5

Wha?
I'm not "looking down" per se on anything. I just don't prefer Panasonic when it comes to the character of their image, it looks "flat" or "thin" to me regardless of resolution or bit rate I view it at. Obviously, there are others who like or even love it, which is super for them. No hate here. Each to their own. 
My guess about YT's compression algorithm is a doubt, not anything prescriptive. I don't work for Google so of course I couldnt tell you their future intentions. I based my doubt off of what we've seen in the past and today.  As of today, 8bit is still the distribution standard. If that changes, great! Right? 
My "arguement" was actually in support of not looking down on 8bit rather than turning up my nose to it. Also, to get away from at size perceptible banding you really need to be at least 10bit, but more realistically in a 16bit + colorspace. 
I think there's a buzzword when it comes to 10bit right now and a misconception that 10bit means no banding. I've been a designer for over 25 years, that's simply wrong. If we're being rententively honest, you'd have to be in a 32bit/float colorspace to get zero artifacts/stepping, as far as pixel peeping in concerned. But ppl don't watch content at a 500% crop, unless they're anally retentive, so does it even matter? 
Maybe I didn't articulate this well, but basically dont worry about it. Banding, it's there, even if you cant see it at 100%, and a reality for most of us, just concentrate on making good content instead, because that's what will determine the success of it the most. 
The video you linked is very impressive on my 10bit BenQ 2.5k monitor. 
I never said YOU were demonizing anything. I don't think we're actually opposing one another here. 

Sounds very logical. 
When I worked at Microsoft, you'd be suprised how often tech companies sabotage their competitors and even themselves. Very, very politicial. Teams of various products competing constantly for budgets/headcount, and a lot of ppl being thrown under bus. The net value is the consumer receives the crap shoot of this, and marketing teams have to scramble to make somethiing out of nothing. Most of my job there was fighting to keep my job.   

I'll have to check those out sometime. 
Soft focus can be used as a narrative as much as anything else. I really like when talent moves into the plane of focus especially when it's shallow. It has it's purposes and can even make accidents look intentional. ?

A lot of tech companies make extraneous claims about their own products. Sometimes the self awarding is warranted but that's the rare exception. 
And are you sure that's not the perception you've prescribed to them? 
No camera manufacturer can meet every demand of every person. What one camera lacks, the other presents, but lacks 2 features of the next one and so on. At all price points.
The Alexa is often considered the litmus for other systems to measure up to as far as image. But is the Alexa a perfect camera? Not even close if the perfect camera to you is something you can hold in the palm of your hand and place anywhere. 
If you're happy with the image of the GH5/s, learn to manual focus like a seasoned Hollywood focus puller.
Hollywood goes to considerable lengths to acheive the image they want around tons of limitations and obstacles, but they still manage to get things done and give us stories we want to pay $20 to go see. They don't pay much attention to the marketing campaigns of camera manufactures because most of it is b.s. 

it means theyre gonna fuck us again! ?

There's nothing (not even) similar to FUJI... That's the most close to film capture in the digital realm, ARRIs included*.
* I only don't add here Blackmagic because I really can't :-)
 

It is not true!
(that guy is an entertainer)
Far from only 1-stop faster. It is beyond 2 stops to be conservative.

How about your experience? Are the diopters useful or not?

Funny that about 36 hours ago, even without camera to test, I had mention 3 stops seemed to me too much:
Here comes this one now:

@jonpais My dear fellow of these boards, I am. Just didn't express my opinion for the subject matter.
Nice to read your heads up! : )
 
Changing topic, here's another GH5S sample from distinct settings slowmo included; seems promising:
