Check at 10:20, 4K standard seems alright, fine..not so..
 

I believe at the 0:38 second I saw the Video Sound Police violently interrupting the shooting!

Don't. 
Sony UWP-D21 is the standard for the minimum threshold for prosumer budget wireless.

Sorry @Rhood haven't try them on a job yet, just received them!
I have serious problems doing sound with all these various Nanlights. Good output, for sure, but very noisy cooling systems..

I know there's tons of tests out there and each one will reach some conclusion; but I also know I personally own both cameras and for me and the type of content that I shoot and the temperatures that I shoot in, the R5 overheated for me while shooting mostly photos with a few video clips here and there when the ambient temps were around 86F and 70% humidity whereas the R7 has never given me the overheating warning even when shooting in ambient temps of around 100F and the humidity was around 10%. 
The R5 was on FW version 1.5 and I haven't shot any video clips after upgrading to FW 1.6 since the R7 is now my go to hybrid camera. Another annoying problem with the R5 is that it still has the 30min record limit. I have to believe that Canon will remove that limit soon, but until it happens, I will just remain in disbelief that they removed it from the R6II, R7, and R3 but have yet to do so (if they ever will) for the R6 and R5....and we are talking years after Panasonic and Sony removed theirs.
As far as DR and IQ, I believe it would be very difficult to tell the difference between the R5, R6, R6II, and R7 in real world shooting (not pixel peeping). Even the R7's line skipped 4K60FPS is more than sufficient for social media content. I've also gained a new appreciation for crop sensors since owning the R7. The extra reach it gives me with the 24-105, 70-200, and even the 24-70 took a little getting used to but its a real treat to work with now.
I think the two main limitations that the R7 has is the fact that it does not have a dual native ISO so it can't compete with the R5 for lowlight and that line skipped 4K60FPS is definitely noticeable in the pixel peeping comparisons.

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

As I said before, it is a "fast turn around" camera, with a weak codec, but that's the beauty of it, the simplicity. Stick an 18-135 or an 24-105 and shoot all day..it was a workhorse camera of the "plain"  professional. Ready on its bag, ready to shoot in 7 seconds and for a full working day 
If you take care of the basics, the camera does the rest of the magic mixing and produces an image that punches much above its weight.
I am still waiting for a similar workhorse camera. Just put some modern internals on the same body Canon, that's so easy..
I wish they C70 was that camera, but unfortunately it doesn't feel the same.

I still use my NX1 with the 16-50mm S and 45mm f/1.8, the colors and character of the 45mm f/1.8 ... Oh my god.

Practice practice practice and a lot of dead ends!
Year 1, 100% photo + 10% video
Year 2, 100% photo + 20% video
Year 5, 100% photo + 50% video
Year 10, 100% photo + 100% video
It’s been like learning to juggle. I started with just 2 balls, added another each year, dropped them more times than I’d care to remember but otherwise dedication.
Plus the tech these days is better than it was 10+ years ago.
I’m always amazed that MORE are NOT doing it, but as long as it is not the norm, good for me and my business!

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 !

I was using 3 cameras when I was doing weddings photography, 2 NX1 and an NX500 with a speciality (oddball lens) on it. All these cameras were on me at all times, but never both video AND photo. Still can't comprehend how you do it. I always have a partner/assistant with me, even for the easiest of jobs..
Sometimes we were 3-4 people for video and 2-3 for photography..
An 24-70 as a workhorse was the most used lens usually, 24mm is good for small group photos, and 70mm is an alright focal length for portraits. The oddball lens on the NX500 could be the amazing NX fisheye or the pancake 16mm..the workhorse lens was the 16-50mm (24-75mm equiv) and 2-2.8f. unique lens and always negated the need for the Sigma 18-35, as at those mm (at 32-33mm to be precise) the NX is 2f, with an incredible I.S, both wider and longer. With the other NX I was usually using the amazingly small 45mm 1.8f for more "artistic" portraits. This lens has a ton of character, especially for the silly price..
Just a different way of doing similar things, I guess!

..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..

The R6II has breathing compensation as well.

I guess I can see why some people might feel like the C100 is too big, if they've primarily shot with mirrorless cameras, but it is, in my opinion, the perfect size and was very comfortable to hold. I would trade the mirrorless camera ergonomics for that kind of body any day.

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. 

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.

The c100 is one of my favorite cameras I've ever uses when it came to size and form factor, I just could never justify the price even on the used market. It was just so comfortable in the hands, at least for me. 
It'd be hard to "go back" to a c100 given all the new features that have come out since, but I think it absolutely would still hold up IQ wise for a lot of work. You probably wouldn't even need to use software like Topaz to upscale it to 4K.
Less DSLR style bodies and more C100 style bodies plz. 

..  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.

If I had to make a choice right now about what system to go all in on it'd be Sony. But I wouldn't be happy about it. Like @MrSMWit's not that I hate Sony, it's just I'm not inspired by them. I don't ENJOY using their cameras and I've never been a big fan of the images they produce. It's not that they're bad, it's just... They're Sony. 
The FX30 is nothing special, but the price? It's hard to beat. It'd be very easy to buy 2 or 3 of them for my work and be done with it. And the system's long term health is guaranteed. 
I'm thankful though that I'm not in a position where I need to make that choice, and can further see what everyone else does in the next year or two before deciding what direction I go in. I'm probably putting too much faith in Panasonic, but I do think they'll announce something big next year. I think they have to, their long term viability I think depends on it. 

The two industry standards tools for dialogue clean up is iZotope RX and Cedar DNS, anybody doing this seriously professionally would have both. 
Brusfri is what I'd recommend in the past instead for people doing it casually with "no budget".
