When I watch tests like this, it reminds me how much I dislike gratuitous slow motion. I think every filmmaker should be given a lifetime allocation of 10 minutes of slow motion that they can use judiciously throughout their career. It's like exclamation points: I remember reading a diatribe against them in which the author said that every writer should be given a lifetime supply of exactly one exclamation point.

New firmware update bringing more ALL-I options, Eye-AF & new Canon 709 profile:
@herein2020 Sadly still no (vertical) aspect ratio markers, I'm sure that would have been easy and very handy to have 

OG C300. Looks amazing. A C300 and a proper colorist / subject will give you much better results than a C70 or C300 Mk3 without.
 

Eye-AF should work ok, it does on my R6 with adapted EF lenses. The new Canon 709 is a modified version of the popular WideDR profile with better highlight curve and added contrast. Perfect for fast turnaround projects imo. ALL-I is nice when you want ultimate compressed quality, difference is noticeable in water scenes and motion. Bigger files for sure but easier to edit. 
I think its just nice to see updates with added new features. Not something Canon is known for. I'm assuming the FX30 and its aggressive price point is probably prompting Canon to do so. Competition is good for us customers. C70 keeps getting better!
They should put out a C50 in a R6/R7 body with full C70 video features under $3K.

I'm not saying C100 is the most compact or discrete camera out there. I'm just saying compared to a rigged up mirrorless offering similar run & gun options its quite comparable, more balanced, all-in-one alternative. 
And yeah C100 SOOC look using Wide DR has a special mojo. Canon had some kind of special sauce back then, the internal processing was 444. 
Speaking of it kinda makes me miss it to be honest ! 

OK so once again armchair expertise. You tend to make a lot of strong assumptions and present opinions as facts on subjects you really have zero experience with. Googling photos, watching a video on YT.. then arguing online against people with actual hands-on experience on the subject matter. Its a recurring theme I've noticed..
Again you lumped the C100 & C300 in the same category. Anybody that has used those two cams knows they are day & night in form factor, weight, operation despite them looking similar on internet pictures.
As for context, OP uses a Z6 plus an Atomos. Fully rigged that's already bulkier and heavier than a stripped down C100. To use your analogy its more like a sedan.. with a camping trailer attached to its rear!

..and again the C100 has built-in NDs, fan, all day battery life, WFM assist tools etc. even when stripped down.
Rigging the equivalent on a large sensor mirrorless will not be smaller or lighter, hence my point withstands. 

Sure you can rig up any cam, but you've also got to factor in the added cost.
An R5C + ND adapter + Tascam is already a whopping 6K€.
As a strictly all-in one cine body C100 is a pretty compact (and affordable) considering its a decade old! 
The R5C, FX3, FX30 are really a new kind of compact hybrid mirrorless camera though.
I like FX3/FX30 fairly better concerning form factor as they are more compact, have mounting options, a native top handle and XLR as well as IBIS equipped and decent battery life:

VS

 
For all day battery life though you are also going to need a big source of external power for R5C (imo its biggest con) adding on to weight and bulk. And pretty quickly you're in a situation that makes 1DX3 feel light and tiny..

You actually do not have to shoot vertical to get vertical video, most of my content I post on YT and IG and the content fits perfectly on both platforms. I would much rather shoot landscape and have the option of posting a vertical version vs shooting vertical with no ability to post a landscape version. The trick is to set up the aspect ratios in Davinci Resolve, and when you are shooting, frame the content in a way where it will work in both orientations. 
One of my favorite features of the S5 was the ability to set up aspect ratio guides which I used to frame the social media content within the landscape orientation. This is also why I discovered the bug in the C70 which does not let you set a custom aspect ratio; so far Canon hasn't bothered to do anything about it. I've been shooting this way so long though that I mentally adjust the framing to accommodate both in post.
Here is a sample video where it is in landscape:
 
 
And here is the same video on Instagram:

..and for exactly those reasons (form factor, weight, operation) a C100mkII is a better option than a C300 these days!
The C100mkII is absolutely my favorite camera for run and gun video work. I have done literally hundreds of travel and music doc episodes good enough for Greek TV and corporate and others. My previous favorite was, sadly(!yes, it was a Sony, do not judge me!), an EX1, another workhorse of that previous era.
If you want a super easy system to shoot most of your "basic" stuff with super fast turn around times and you do not mind the "weak" codec, even now is an excellent option..For extremely fast run and gun the 18-135 was ace, if you had more time one could use the whole EF selection. My ultra fast and portable kit was the 18-135, an 70-200mm 4f and a nifty-fifty used for some interviews. My most enjoyable set up of all time..great times!
..I didn't like the C300 (and C200) ergonomics, but they were also standard on most of my business back then.
oh my.. I want one now..

I haven't proven any point other than it is all relative to what camera you are comparing with.
You choose to call it "huge" compared to your GH5 or a Gopro. 
I am indeed saying it is small compared to most cinema cameras but also action sport mirrorless or a rigged up Z6/R6/A7 with external monitor.
I'll stay it again,  the C100 is small considering it has: built-in NDs, an EVF, large display, fan system, all-day battery, XLRs.
It's like the Pocket 6K Pro. The term "pocket" is really relative but makes sense if you compare it to an ARRI.

..  it is really a small camera when stripped. maybe not Komodo small but considering its got NDs, EVF, Display, Fan..

weights about the same as a Z9, R3, S1H etc..

I love the C100. Still a very capable camera. I only sold it because I can't deliver FHD anymore, even 4K downsampled. The 8-bit is also a challenge and now that I'm more into grading I don't think I could go back to 8-bit. But the SOOC IQ still holds up even though it has Canons older CS which may look more dated than the more neutral CS of recent generations. For me personally, C300 mk2 would be the only older model I'd be able to do pro work with but if you're a hobbyist and looking for one of the best FHD cams, the C100mk2 or C300 would probably be near the top of that list. 
By the way, C100 isn't large at all, C300 has that awkward tall form factor though.

Hey whatever works best for you. R5C vs C100 is an uneven comp on so many levels. That said I maintain that to get all day battery life, NDs and XLRs on R5C, you're looking at a rig and investment far away from what the C100 gives you from the get go.. and no I'm not going back there either but for under $800 if you're ok shooting FHD, still a fantastic option imo..

As an R6 user, I can tell you this is going to be Canons best selling camera (which R6 already is). 
It finally eliminates recording time limits and overheating at 4K30p. That alone is major.
Adding false color, specific easy video menu, focus breathing comp and other video centric tools is fantastic. 
DPAF 2 is indeed killer.
The faster read out times surely means lower rolling shutter. 
Really seems like the perfect mid-tier mirrorless. I don't see any cripple hammer, aside from no ALL-I codec so you'll need an M1 Mac to edit the 10-bit Log footage. Aside from that detail this is an A7IV killer.
Needless to say my R6 is going up for sale today.
Here is a pretty good rundown of the camera:
 

Well yeah you'd assume sensor & processing go hand in hand, but if you look at XH2/XH2S, here are two cameras with identical processing but different sensors, one stacked the other not. XH2S's stacked sensor allows fast read out that enables super low RS but also 14-bit processing. It does give up 8K in favour of 6.2K and is a bit more noisy. Stacked sensors are also more expensive to produce so that does add a bit to the cost. 
To me that's an acceptable trade-off. But I think that most manufacturers feel that a cheaper camera with 8K/45MP will be much more of a sell factor than more expensive faster read out 6.2K/26MP camera. Fuji were smart enough to give us both options but at Sony/Canon/Nikon, they seem to reserve the speedy stacked sensors for their expensive flagship sports/action cams. That probably won't change any time soon, so just wishful thinking on my part but I'd like to see a fast "XH2S" type hybrid from the other big players that isn't a high megapixel sports camera. like an FX30S, R6S, Z6S..

As recently discussed with you in a parallel thread, increasing MPix will inevitably decrease RS and overall read out among other things. That is why R3 has much better RS in video than Z9 or A1. Or can do 195fps max burst rate at full resolution in FF vs 120fps in 11MP crop mode for Z9. It's always a give & take. And depending on the user that will tilt balance in either direction.  
Again I think Fuji did the smart thing with XH2/XH2S giving the user the option of super fast readout or high resolution 45MP/8K.
Finally I think the R3 sits just fine against the A1/Z9 and given the choice I'd pick it over the other two. But that's because I value read-out speed in both photo/video over super high resolution. 
In the end I'm not a sports/action shooter though so no real need to invest in such cameras. I just wished there was a fast stacked sensor in a non flagship action/sports oriented body. XH2S fits the bill but I'm not sure I wanna head back to Fuji system for other reasons.

I updated the FW to 1.6 as soon as it came out, it froze 2 days later on a photo shoot...shutter button stopped working until I restarted it; back screen and everything else kept working, just shutter button wouldn't do anything when I pressed it....not exactly confidence inspiring.
Yes the EVF delay for photos is in all mirrorless cameras but it seemed excessive to me so I opened a ticket with Canon and paid $150 to ship it to them and they returned it saying nothing was wrong. The R7 has the same delay, if a person blinks while taking their picture, in the EVF their eyes are still open, when reviewing the image their eyes are closed, runway shows are the worst for me, the front foot is on the ground in the EVF, in the captured image they have already picked it back up, little things like that are decreasing my keeper count.....definitely making me miss my OVF especially since I typically have a flash setup so I can't just spray and pray; and yes I have tried the higher FPS mode for the EVF.
I had a ballerina jumping and doing twirls for a photo shoot....that was the worst, I was ready to throw the camera out of the window, there was literally no way to do anything except just hope for a few keeper shots; I had multiple flashes setup so again...no spray and pray option due to flash recycle times.
The R7 is quirky too....sometimes the hotshoe doesn't trigger the flash, I know it is not the flash because it is the same flash I have had for years. Also, pressing the record button while it is recording doesn't always stop the recording, requiring multiple presses. After stopping the recording there's a delay of approximately 3-5s where you can't record again as if the buffer is clearing out or something like that; the S5 did not do that.
I really think Canon's cameras have become so complicated that they have all the sophistication of modern computers along with all of their intermittent issues. 
So yes, when I am on a photoshoot I just don't trust the R5 it is that simple; I don't want the photo side of it to lock up or have an issue because I was off shooting some b-roll video since I value reliability above all else.  I got used to a dedicated photo camera with the 5DIV's rock solid reliability (its video was unusable), so after those issues early on I will treat the R5 the same way. Ironically, I trust the R7 more as a hybrid than the R5.
But back to the R6II 🤣 I noticed another feature they brought to the R6II that the S5 had in 2020.....the big red recording box. This is a great feature to verify that it is recording (and another feature that could be brought to the other cameras via a FW update).  I couldn't tell from the CVP video if the box stays on or just shows when it starts recording.
 
I absolutely hate proxy media because of how much time it takes and because of my particular workflow (I only import the exact clips that I need for the project, so I would need to create proxy media each time mid project). Instead, what I do is scrub through and find the piece of the clip I want, then cut it up and add it to the timeline then use optimized media since it is much faster because it is creating a proxy of just that part of the clip. 
It still stutters during the initial review process; mainly on 60FPS media. I am still waiting to see if the NVIDIA 4000 series video cards can accelerate 10 bit 4:2:2 media, for some reason that information is impossible to find and I search about once a week or so. I suppose I could email NVIDIA and ask them. It is very disappointing that in 2022 PC users still have no video card options for 4:2:2.
What you will discover with the EF 70-200 adapted is the same thing that I discovered; AF is the least of your problems. The real problem is the weight of the lens making your camera feel like it is going to tear itself apart. With the EF 70-200 lens on the R5 plus the adapter the whole body was flexing, the adapter and the lens mount was making weird noises, and it really felt like the whole thing was going to fall apart.....vs the 5DIV where the two fit together like a glove.
The flexing and sounds were so bad I ended up getting the RF 70-200 since it is my most used portrait lens; actually, it is my most used photography lens of all time due to runway shows. So yes.....YT reviewers really gloss over a lot and you don't learn details like those until you actually try to use it. I think it is both the length and weight that make the combo so bad, I assume there are RF lenses just as heavy but not as long.

well just like the original R6, it has better FF 4K60p IQ as it oversamples with no line skipping unlike R5 FF 4K60p.
as already mentioned, R6ii has new stuff like the smart hotshoe for Tascam xlr audio, a very handy stills/video switch (R5 requires mode button steps), the latest AF system with deep learning and C70's detect only, false colour, aspect ratio markers & pre-record buffer. a 10x FHD zoom. Focus breathing compensation. A new OVF simulation for the EVF. And as you already know no 30mn time limit and no overheating at up to 4K30p.
its basically a better all-rounder and substantially cheaper when buying new, especially here in EU.
if you don't need 8K RAW, 4K120p or 45MP it makes much better sense.
 
 
A step down from your 5DIV how? the only thing I can think of is the megapixel count (30 vs 20).
DXO ranks the R6 above the 5DIV in terms of DR and ISO noise performance. R6 does use the flagship 1DX3 sensor..
As for the R5 overheating, it has been substantially mitigated with v1.6 : 
https://downloads.canon.com/EOSR5_recordtime_7-21.pdf
With the high setting its basically a non-issue. So again a bit of a waste not to benefit from it for FF video. I also have battery grip, shoulder strap etc on my hybrids, that doesn't prevent me from shooting some quick handheld video bits during events thanks to IBIS. 4K120p would be even better handheld.
But ok you have it dedicated to photo duties and a C70 + R7 for video. That's a nice setup. 

Yes in this French review at around 14 minutes:
 

I don't think any manufacturer can win on these boards.
Yeah, Canon gets a lot of criticism.  A lot.  
But so does Sony.  People say their older cameras had intolerable colour science, their lenses are too expensive, their image is soul-less, people who like them are shills etc.
Good luck having a conversation about Panasonic without being drowned out by people talking about auto-focus like they have Tourettes Syndrome, and if you're talking about a MFT camera then why would you - the mount is dead don't you know? and didn't Panasonic used to have a cinema camera division......?
Fuji is criticised for not having FF options, despite offering S35 and a range of Medium Format cameras that produce lovely images, and is currently laid bare with people doing extractions of the Cr channel and wondering WTF they are doing to the image to make them so awful..... in a dedicated thread.
Sigma is loved for having one of the nicest sensors in many years, provides 4K and high-res models to choose from, but is criticised heavily because it is secretly the successor to the OG BMPCC with lovely images and almost nothing else going for it.  Plus, you know, almost no-one bought one.
Olympus?  Aren't they bankrupt?  Did you know they released a new camera recently?  No?  Neither did anyone else - there's no mention of it on here at all.  The worst kind of criticism is being ignored.
Pentax?  The 80's called and wants it's camera back!
*cough* Samsung *cough* NX-1 *cough* better go have a covid test......
