SOOC my ass. You can say a Canon T2i has a better color science, it might be better than the GH5s, but it doesn't mean it is worth a crap to compare to each other. Hell this is sort of suppose to be a Cine type forum not a beauty contest. Ohh my Reds are better than your Reds is what is happening with this Fuji X-H1 on here. It is a nice camera but it is like comparing a Sony FS5 to a F55. Both are good, one is great. That is what I think is the difference.
It is amazing how few people on here even give the GH5s a look let alone talk about buying one. It is a miracle camera for the money. You can make a living with it. A feature movie. There is hardly anything it can't do. And there is like 20 people on here in a Cine forum that could gives a shit, and there is 1,000 that think the X-H1 is the second coming of Jesus Christ! Crazy place, just crazy LoL.

Muaha, lol. That compression blocking is massive, it´s like old 256 VGA color mode from 1998, muaha! Some tint easily corrected with a color wheel in the software of your choice. No cure for the A7s image on this 12800ISO sample. So up to 12800iso, comparable performance, even much  better on the gh5s in this scene.
But let´s read what master Ebrahim has to say about this, giving his supreme analysis on the dp forum very soon!

Quote from the video comparison with the a7S:
 

I've been saying this for a long time that is the downside of the a7S, what good is insanely lowlight if your shallow DoF is impractical??

With the GH5S you can shoot both in low light *and* a DoF that makes sense for the shot. 

Dude wtf!!!! Nice work. So this is all v-log in you're reel??? Give me some pointers on your setup with the Gh4. Your work is nice.

I second that. But @64mulford,  you must put deezid at @deezid,  so he can recognize our plead much better!
I reposted deezids Americanah trailer in the GX85 thread to show among other posters, how awesome Panasonic Lumix material can look.
Can´t wait to see Andrew´s footage with this powerhouse the GH5 must be. 400mbps will offer perfect quality
for indy and documentary shooters, if GH5 has the same high standard of quality control/mangagement, which the
production of the GH4 had.

Man, you have to do a tutorial on grading V log! Amazing!

I actually trust Kholi as well, but not this time. Comparing V-Log to S-Log on the A7sII? C'mon... 
If it is nearly as good as V-Log on the GH4 it'll put the A7sII to shame in terms of color science.

Watch my showreel to see what I mean:
Almost 99% internal V-Log!
 
 
And yes, I've been using the a7sII quite a lot, always struggeling with the color, even using different profiles and combinations (such as Cine4, Slog2/3 SGamut 3.cine/3/2 etc). On the GH4 I just hit the portrait profile with:
Contrast 0
Sharpening -5
NR -5
Saturation -2
Hue 1

And it looks almost identical to the color corrected RAW output of the FS5...

There is no better endorsement than from the people who wouldn't know a bitrate from a pixel.
This covers 99.99% of the world

After a weekend playing with the GH5 and 2 years of the GH4 I am happy with my purchase. Did the improvements warrant the hefty cost and the upgrade in general? probably not for me, as I am just an enthusiast who loves filming family occassions and taking his camera around with him whereever he goes. I am sure all the fancy stuff under the hood would be more noticeable to those using the gh5 to its limits for paid work. I was looking mainly for stabilisation as most of my work is handheld, and this camera delivers on this in leaps and bounds, especially noticeble with non OIS lenses. 
I purchased vlog and after some initial trials I am back to using standard profiles. I shot some standard footage over the weekend and showed it to my wife and mother in law , 10 bit 4k 150mb in standard profile and the first thing they both said is "wow look how amazing that looks...it feels like you are there!" Now these guys are not pixel peepers, and they watch my footage all the time and are used to high quality hd footage, but this change from the gh4 to gh5 was instantly noticeable to them, the humble viewer who normally wouldnt care if something was shot on an iphone or not!
Low light seems to be better as well, and with a bit of netvideo you can get really clean footage....
All in all if I hadnt have managed to sell my GH4 for £1000 I would not have been able to consider and\or afford the GH5. As it was though, it was a £700 purchase for me, I already had lenses so as it stands I am very happy!
 

Same here, and I'm pretty much a Panasonic fanboy. I'll wait to see if Sony does anything at NAB, or whatever the next photo tradeshow after that is. And I'd like to see how the 400mbps firmware looks, as 150mbps is a little light for the high-motion stuff I shoot.
Ahhh, who am I kidding? If I wasn't broke I'd probably have it already

James Miller demonstrates that this is an codec problem that disappears when an external recorder is used, suggesting that the 400mps upgrade will help or elimaite this occasional problem.

When you are naming as a reviewer some negative things (cons) about a camera, you are referring to things that should be there, considering the company's marketing, the product's price and the competition in this specific price range. HFR is softer than regular 1080p in all cameras since faster sensor readouts come with compromises, at least for now...But 180p imagery, slightly softer than Pana's tack sharp 1080p is not a "con", this is what I am saying. It is called "gift".

It's a problem that only came up when cameras got smaller and lighter.
They don't have a lot of inertia anymore and thus require an active effort to be keps steady,

This is always the problem with A and B comparisons.  It is better not to look at them, unless you own the better camera.

The camera has normal size micro 4/3 senser, accept it...

For the multi-aspect ratio discussion, it doesn't look like one at all. Everything looks like standard Micro4/3 sensor, I think that ship has sailed.
As for the 400Mbps All-I comment I made before. Two of the guys that shot the GH5 promo videos replied back saying that although there is nothing official, they think that the 400Mbps All-I is indeed H.265 and NOT H.264. Nick Driftwood also replied back since I tried to confirm what he said during the Live Q&A and he said "it would HAVE to be h265 I believe :-) dont you?!".
When I wrote about wanting H.265 as an additional option I thought Panasonic wasn't really bold enough to pull it off but since the GH5 already have the HEVC encoders and these guys think the firmware update will bring H.265 400Mbps All-I, although there is nothing official about it, I don't doubt it will be indeed HEVC.

When compared to FF video (16x9 cut of a 24X36mm sensor), the GH5 with the XL booster would be a 1.33x crop, and with the Ultra booster it'd be 1.47x.
Remember that the XL is less uniform in sharpness across the frame- it is a little sharper than the Ultra in the middle, but softer outside of that. The Ultra is more consistent.
Also remember that with the sensor moving due to IBIS, you end up effectively using a larger image circle than without IBIS. So even if IBIS only moves the sensor a mm in each direction,  your 13x19mm sensor now needs an image circle that can cover 15x21mm.
So APS-C lenses with small image circles, like the Sigma 18-35mm f1.8, which barely cover the sensor with the XL booster, may now go soft or dark in the corners as IBIS shifts the sensor. Or worse yet, you may have the actual edge of the image circle show up as black corners.
This is why I think it's safer to go with the Ultra booster for the GH5.

On the H.265 and HEVC topic and 400Mbps:
I was assuming that 400Mbps All-I is H.264 but there is nowhere saying which codec is it and when I asked Nick Driftwood on a Live they did on Facebook, he said like the 400Mbps codec was actually H.265 and it would be equivalent to a 800Mbps in GH4 since HEVC has about half the size of AVC.
I'm not sure if he made a mistake but that what he said.
That's something I wrote about some time ago and that it would be interesting to have H.265 All-I version for the GH5, so if it's true and the GH5 is providing both H.264 and H.265 codecs, that's very interesting and quite future oriented approach.

Funny how some of you guys have something to cry about when they're giving you a camera that's doing everything other video cameras are doing at thousands of dollars less. 

Yet I'd say that's a clear bottleneck there... Never edit off external USB3 drives, and even less if they are mechanical drives. That's an "on the field" solution, but you'll find editing with internal SSDs is much better (faster, more responsive). Also using only 2 drives is another bottleneck.
It's great to have the software running on the NVMe PCIe drive, but kind of useless; I guess the OS and Premiere load crazy fast, but once Premiere is loaded, it's loaded -and the drive becomes irrelevant-. It's crucial to have your software/OS on one drive, your source footage on another and your render/temp files on another so that you can use all of the drives at the same time and maximize the SATA bus. Keep in mind spinning discs have a slower access time (regardless of their read speed), especially when they have to access two pieces of data in faraway sectors at the "same" time. It wouldn't be so obvious with a single SSD editing drive because access time is much faster, but you'd still be able to tell the difference between a system with a single editing SSD and one with several HDDs accessed at the same time. It's better/faster to have 4 or 5 "slow" HDDs than a single SSD.
That's a Mac problem. PP uses a lot of RAM (the whole Adobe suite does) and in Windows it is much easier to control what is open and running in the background. MacOS is notorious for having tons of processes and apps running in the background. Since macs are usually overkill, the user experience is great -we've all heard people say that apps open much faster unaware that they were never really actually closed-, but when you want to push it to the limit it just doesn't deliver like a windows PC does. It's just a question of knowing the limitation and accounting for the necessary overhead. I recently upgraded the GPU in an old editing suite (GTX 1070, i7, 32GB RAM) and it edits 4K without proxies and without hiccups. It's not as fast is some processes as the new suites, but does the job without crashing/lagging or any of that.
You'll see that a single fast processor is better for Premiere. It doesn't really take advantage of dual Xeons like a 3D app does. Still, with such a beast you should consider a multiple drive configuration. You can go the HDD route (RAID) which would require many disks -but cheaper- or go all SSD which would require just 4 SSDs since there is no need for RAID configuration.

Subject tracking is surprisingly good. The stabilization is impressive.  If they can get a little more aggressive with the roll axis stabilization it'll be a huge improvement.  I think we are about 2 generations away from matching the performance of gimbals.  Still very useful with some warp stabilization. 
There stabilization noise is an issue.  But its not a deal breaker. 

I own the GH4 and just rented the GX85 to have a B cam for a wedding. I used to love the image the GH4 produced, until I used the GX85!!! It is sooooooo much cleaner, and the IBIS is a lifesaver.
Let's put it this way: When I went through the 180GB worth of video for the deliverable, 95% of the content I shipped was recorded with the GX85, as at the high ISO (1600-3200) the GH4 was undeliverable.  If the G85 is anything like the GX85, 4K delivery will be awesome.
