I'm happy they chose to keep the camera light, and deal with overheating in the extreme modes rather than choose to make the camera large in order to avoid it.
I don't think there is much point in a pissing match between Canon and Sony.

As I was watching it the first time I was actually rooting for it to lock-on when I saw him run away. Then it did actually snap on for a fraction of a second.
It had a weak "Sony moment".
Evidently, if you overheat the R by shooting 20 continuous minutes of 8K RAW, it will punish you with animal-butthole-AF

I understand though that some will be disappointed in the R5's inability to record long duration video at the highest quality settings.
I for one, am incredibly excited about the 20fps 45mp sensor with Sony quality AF, Canon ergonomics, and RF and EF lenses....Show more →
Someone pointed this out on another website...but here's one way to think about it. The Canon R5 can do about 20 min of 8K video...that's its limitation. But the other mirrorless cameras, including the Sony, including the new Sony A7sIII that's coming...can do 8K for zero minutes. That is its limitation. So I'll take 20 min or so rather than zero as a limitation.

Well, there is more fine print. There is overheating on all oversampled OR high frame rate modes. That is more unfortunate to me than the limitations on 8k raw. 4k30 and below will have to be set to the lower quality (tbd if it is binning or line skipping) mode in order to avoid overheating.
On a related note, I am pretty curious what the teardowns of this camera would look like. It is possible that Canon omitted thermal pads between the cpu and the metal chassis, making it difficult to dissipate heat. Only some time will tell.

This is one of the more level-headed commentaries about 8K and so-called overheating issues.
Instead of an overheating limitation, the R5 is proof that every other FF mirrorless body of similar price has the real limitation of no 8K video at all. For the few who can use it that is.

Q and A starts around 19:00 mark.
One Youtube comment summarized it:
Some interesting points in this video, which you may consider if you're looking at the R5 or R6:
EOS R5 Overheating - 52:24
• 8K raw: 20 minutes (52:32)
• 8K compressed: 20 minutes (52:32)
• 4K 120fps: 7 minutes 30 seconds per clip, 2 clips total before overheating (56:00)
• 4K 60fps no crop: 35 minutes (56:32)
• 4K 60fps crop (oversampling 5.1K): 25 minutes (56:53)
• 4K 30fps HQ: 30 minutes (57:41)
• 4K 30fps HQ disabled: no record limit (57:05) and (57:41)
EOS R6 Overheating - 1:01:55
• 4K 60fps no crop (oversampled from 5.1K): 30 minutes (1:02:13)
• 4K 60fps crop: 45 minutes (1:02:51)
• 4K 30fps no crop (oversampled 5.1K): 40 minutes (1:02:43)
• 4K 30fps crop: no record limit (1:02:58)
Additional Notes
• When you start recording you'll get a time estimate on the screen (55:48)
• Having the camera turned ON in standby mode will increase internal temperature (55:20)
• There is an option to lower display resolution to help with overheating issues (55:06)
• There is the option to record to an external recorder to bypass 4K 60fps recording limits (1:01:28)

The video I posted a couple replies back, from Armando Ferreira, interjects something different from the old specification rut that DXO can get bogged down in.
The 8K may have something in common with nitrous oxide.
Was nitrous oxide a limitation when first used for drag racing? Or was nitrous oxide a huge advantage for the first racers to use it?
Apparently 10 to 20 pounds lasts maybe 3 to 5 minutes of duration. But it's going to vary. Just as racers had to figure out when and how to use nitrous oxide, users of 8K will need to learn how much they can use it in various temperatures and shooting conditions.
As a feature that practically no other brand offers, about the only practical way to look at 8K is an extra, not a limitation.

Agreed that the 8K can be looked at as an extra and one will learn and work around its limitations....the issue is going to be when a number of other cameras have less limitations on all the 4K options and therefore are seen as better options to everyone except those dead set on 20mins of 8K every 2 hrs.
This is where the R5 may fall behind the S1H and A7SIII...one with active cooling (and no limits) and one rumoured to have some sort of passive cooling (limits TBD)

I am firmly in the camp of disappointment regarding the overheating, but I’m not really *that* disappointed.
Given the entirety of the product, I would choose the R5 over any other camera available. I am perfectly fine shooting non oversampled 4k if I ever find myself in need of long form recording.

I'm not sure that's right for all users. According to Matt Granger, at 23C the camera can go 30 minutes at 4k 30p oversampled. That or 24p would be my normal choice of video mode. I want a stills camera, mainly for wildlife, that I can also shoot short video clips with. 30 minutes is fine for that. I have very little use for slow motion, certainly not for more than a few seconds,
At this point, my concerns about the camera are the codecs and lens selection. (There is not a single lens in the R system I like. I would be adapting my EF lenses,)

The A7sIII will be 12MP and irrelevant to most that aren't heavily into video. For birding and landscape it would be a fairly useless tool for me. Not sure why people think the A7sIII is an R5 competitor, it's a dedicated videocamera in a small mirrorless body that can be used for stills if you want.
The trouble I have is that 8K might be useful if you use it for short burst action photography, 33MP at 30fps using normal shutter speeds of 1/2000s or shorter would be sweet shooting short 5-10s videos and picking best frame, but the sensor read speed won't be fast enough to stop rolling shutter. So 8K is something I thought would be great but now I'm not so sure it will be much use and I don't intend to shoot normal video in 8K. 4K120p is more interesting to me for that but it has worse overheating than 8K30p. Still I doubt I'll ever be shooting more than 5 minute clips for any video mode.

Another way way of looking at things, eliminating disappointment about overheating would have been the easy path for Canon.
All Canon had to do was cannibalize and cripple hammer the R5 by eliminating the 8K.
No 8K .. no complaints .. no negative 8K reviews.
Many video guys would have been glad with just uncropped 4K. Bet near 0% ever even imagined Canon releasing 8K before any specs leaked.
So in some online reviews we see people basically complaining about Canon refraining from using the cripple hammer.

Exactly. 12MP was decent for taking photos when the original A7s was released back in 2014, but today? Quite niche for photography besides dark venues Where you are shooting at high ISO, I would think. The Sony A7sIII is pretty much strictly a video camera with an outstanding lens selection In my book.
