Yeah with the same body size I think you are correct. But, but one thing this new sensor that is in the GH5s, which seems to be a Sony, is that it is more efficient ,so less heat .If that is true that it Might be possible to squeeze 10bit out of the same body?? It would be pushing it to the max I think for Sony. I really don't think Sony wants any more negative print in forums  about overheating any more.

I was all set to buy an A7RIII.  The technology is amazing, but then the issues starting coming in, and coming in, and coming in.  Then I started seeing people sell their A7RIIIs.  Way too many engineering and quality issues.  It appears Sony rushed this out the door to take away some D850 sales, and beat Christmas.  Things like Sony lenses that would fit an A7RII, but were too tight to mount on an A7RIII were reported by multiple people.  One guy bought an A7RIII, and it had a stuck pixel in the EVF.  He sent it back, got another one, same thing.  Sent that one back, got another, and third one had two stuck pixels.  Game over!  Then we have the reports of EVF and LCD pixels that turn on for no reason when you go into focus magnify mode, similar to stuck pixels  or sensor hot pixels but they are not.  Extended exposures show tons of sensor hot pixels.  This is with Sony still not fixing the star eater issue.  I started looking at video, and people's skin looks like cardboard.  Or check out Sony's so called "weather resistant" body.
And there is more.  As far as I am concerned the A7RIII is a prototype that got pushed into production on an uncontrolled assembly line.  Now contrast this with the D850 or the GH5.   You have to really dig to find any quality issues.  

Well stated. Like I said since this GH5s has proved you don't Need FF to get decent low light I see no reason to buy a Sony A7xxx camera anymore new to be honest. I doubt Sony is going to come out with Anything that is going to top the Gh5s features wise. How can they. It, other than IBIS, has everything but the kitchen sink in it now. And it is surely cheaper than any A7s mk iii will be. I doubt a Plain Jane A7 mk III will be tons cheaper.
I mean Sony is not stupid, but Panasonic in the last year, and now with the GH5s have given "Normal" people 3 cameras that are pretty much unbelievable for what they can do. They have given people a upward path from a G7 to hell, up with the big boys with the EVA1. There is no real reason, other than if you are Glenn and you HAVE to have Raw LoL, that you need some camera other than the 3 that have just come out as a average, or even half serious Pro. Sure a Arri is IT, but we ain't ever buying one of them, but you can buy a GH5s that in reality ain't far from it, for peanuts price wise, to a Arri.
We all ought to be happy as hell on here, and some people act on here like the GH5s is a piece of shit. A Downgrade of sorts. Hell I say it is a nearly a Arri for 2500 bucks! What can't you really shoot with it? What else , other than Raw, is it missing that would stop you from making a feature film on it? This ain't no Barbie Cam, this thing is the real deal, for people that want to make the real deal.
I think anyone that is serious about this stuff will have no reason Not to buy one I don't give a shit what the New Sony A7s mk III has. I say it Can Not beat this camera, unless like I said, some crazy ass breakthrough and you know that would go to the high end F55, F5, FS7, Etc. first..
The Only thing I see the Sony A7s mk III having is cleaner 52,000 ISO and above even over what they have now. But that is the reason Thomas Edison invented light people. I don't see that a big enough reason to buy it over the GH5s. That sort of ISO is not used very often to give up what the GH5s has to offer. But I am sure the new A7s will be a great product either way. I am not a Sony hater that is for sure.

Yeah but the A7s model is really Only bought by people mostly for Video. I can't see how a few might not be swayed toward the GH5s. The A7r mkIII is 3300 bucks. What if it isn't 10 bit.
That HDMI shit to me sucks on a mirrorless camera. Hell you want a small package and not Have to add a Atomos to it. That is why you bought a small camera, to stay small. Not counting how much that cost. Sure on a Arri Alexa who cares if a 7" monitor is hanging off of it.
I somewhat doubt Sony can get 10 bit out of the same body size without it overheating every 5 minutes. I think Sony keep screwing themselves making the body so dam small. If you are over 200 pounds you can barely put your hand between the grip and a faster, or longer lens. It is like my RX10 I bought, hell I can't even use it. The knurling on the lens kills my index finger. You can make stuff too damn small.
But I am pretty sure the A7s mk III will probably be using a sensor type like that is in the GH5s. But I have no clue how gaining even more ISO is going to make them that much better than they are now for the average ISO you normally use. I guess 25.000 could look like 1600 ISO. Sure that would be nice. But I guess we will see. I am sure it will not be junk. They Have to pick up the pace with this new GH5s.
And most mirrorless cameras are bought by 12 years old girls in Japan. I doubt they are worried about 10 bit. They are worried if you can get it in Pink or Yellow.
What are you doing up this late Glenn!

@webrunner5 honestly, having grown up shooting Super 8 and VHS, I am blown away by what any of these cameras are capable of. Hell, a t2i and a GH1 are insanely better than the mini DV I used for my first short and that was monumentally better than the Hi-8 camera I had before that. We’re really lucky. 

I'd say ISO12800 is the 3200 on GH5, that is, the new territory to avoid, so ISO10000 on GH5S the new 1600 limit on GH5; as my most optimistic bet... about 2 stops and a half for lowlight, not bad. Imagine a f2.8 to let you see light as could be a f1.2 pick. With about 1.15x of crop coupled to SB 0.64x XL version, the new GH5S is the new FF* in town!
Even though, from other samples I've seen I'd even include 12800 (where others have also compared 12800 on GH5S to 3200 from GH5 too, so I believe I should not be too much optimistic over here).
 
* Sorry guys but I love to provoke a few minds from these boards... LOL :-)

Question, where are you getting 1.15x crop? 2 x 0.64 = 1.28, or about aps-h. The image circle in DCI doesn't change the crop factor, its still 2, same for 4/3 or 3/2, the diagonal is alway the same - the diameter of the circle. The m43 diagonal in all aspect ratios is 21.63mm, that never changes, right? You can see from the image below, all the aspect ratios are still within the m43 image circle, so they all have the same diagonal. Unless I'm looking at this wrong, but people seem to be calculating things based on the horizontal width, not the diagonal.

p.s. There's a mint GH5 'Classic' (my new name for the original) for $1500 on Fred Miranda if you prefer IBIS. This is a good time to buy. http://www.fredmiranda.com/forum/topic/1525431

Something seemed odd with the claims floating around the speed booster brings it to almost FF FOV, its closer than the gh5 since there's no crop on the gh5s when shooting video, but its still basically 1.3 (1.28) relative to FF. If my math is correct, but no guarantees since I was a journalism major and skipped algebra for statistics.

@Trek of Joy No, you sound right! I hadn't thought about it. I was lazy and took the value from @Mattias Burling without thinking twice. My bad.

Andrew, great article! I never tested HLG! I need to try that. Seems promising. I did a review of the camera after shooting a doc, a wedding, and vlog and really believe that it’s  one of the best all around cameras right now.

Glenn, in my usual condescend tone addressed to you (sorry, couldn't resist!), no idea if I must say I really do like this post of yours or not... LOL Something I know though, even when I am in doubt or I disagree with you, you still are one of my fav readings over here ;-)

Reason why you're also right : ) I love to quote Nils Bohr for such cases:
'The opposite of a correct statement is a false statement. But the opposite of a profound truth may well be another profound truth.'
As much as Coppola's choice towards GH2 is completely out of tune for many pros out there. Means digital has changed this medium. Deeper than people out of these boards tend to want to believe.

At CES a rep said it's an "all new sensor," which got me excited... but finally found a video where a rep says 12MP stills so it's not looking like a 1" 
EDIT: Looks like there will be two sensor options!
 

It will come. Sooner or later but will come... :-)
Certain PR reps make us to feel children, uneducated or retarded... Make a triple pick LOL

Under motion picture industry perspective, no. The fact is you can mimic any one of the big guys there in much more than 50% of circumstances though. I guess this is where reality fits there. IMO I think they are going through the spot pretty well on that one.

At 8-bit for video, yes.

Like this one ? 

Sure, as much as a billionaire will miss anything if only millionaire... : D I recall when people were used to shoot on film, besides the fact I concur noise can look very filmic too, Blackmagic noise @ low light included.

[PS]
Well, I see such low light technology brings a new aesthetics approach... The question is if that's good or not under this particular perspective. Night life all shot in the same way is... boring to say the least.

Yeah, I think that´s an exellent idea. Minus the osiris lut and color will look better too:)

Better to leave it stuck on 2500 going with the GH5S... :-D
