    There has been a lot of concern recently about how the Canon EOS R5 and Canon EOS R6 handle heat when recording 8K and 4K video. Canon has released an official statement on the issue.
    From Canon:
    Details Regarding Canon EOS R5/EOS R6 Overheating During Video Recording
    The EOS R5, one of the latest additions to Canon’s full-frame mirrorless camera line, offers class-leading autofocus with high-resolution and high frame rate video recording options using the maximum width of the full-frame sensor at high bit rates. Inevitably, this combination of features has the potential to generate some significant heat, which will limit recording time.
    Canon has taken several steps to manage the potential for overheating, including:

    Magnesium alloy was used in the body to dissipate heat away from internal components

    I've been using video capable DSLRs for a decade now and shot maybe a total of 20 minutes of video on them so naturally that's the most uninteresting news I could think of. However, it's gonna be fun seeing everyone go mad about it and construct an issue where there really is none (if you need proper heat managaement get a cinema camera ffs).

    But you've got to factor in the cumulative effect of heat build up over a period of time, not just one take.

    I've pre-ordered however, I find the heat issues a very dissapointing with all these limittions.

    I am primarily a stills shooter, but I can see how overheating can be disappointing. I think these numbers are from a cold start.

    I wonder how it would work if I had the camera on and taking photos here and there, and then switched to shot a short video

    i second this as well as what happens if the ambient temp is warmer

    Oh, you mean to actually use it as a photo camera, not as a dedicated video camera?
    Come on, that's crazy talk! We really want those long, boring YouTube videos to get longer and higher resolution...:)

    4K 30p sounds good enough for me and a great option for normal people. I can understand some people want the 4k 120p option for slow motion but i'm not really sure why the limit would be an issue as how much slow motion would you want to film at once? As far as 8K, I genuinely think its an amazing achievement to have that in a mirrorless body this size and whilst I feel for those that want this feature and be able to have unlimited recording time, realistically unless the laws of physics can be changed, it's not going to happen any time soon. Sorry folks.

    Canon need to manufactures an EF lens adapter with a fan to suck heat directly from the sensor for the long take video shooters.

    Probably any vortex created between lens and sensor may degrade the image quality, because of different densities. The handheld photocamera form factor + weather sealing makes really difficult to dissipate heath efficiently.

    Well that didn't actually say anything we didn't already know???

    Canon need to manufactures an EF lens adapter with a fan to suck heat directly from the sensor for the long take video shooters.

    But that means using only EF lens, right? I wonder, if they could solve it somehow from within the grip? There would have to be some metal part connection, to dissipate the heat though. There seems to be some strange part close to the hinge of the LCD screen. If it would be metal and not plastic, could serve the purpose with some additional tools. But what about an external recorder for such situations?

    I find the heat issue very disturbing. There is a need to have this small sized camera for video work on a gimbal. Few years back I used 7DII to shoot TEDx conference. It was one time job in a life. But I did it. I'll still wait for a full frame camera with interchangeable lens that can shoot 4K/60, unlimited recording time and a decent codec. The R mount and drop in filter adapters could solve even the ND issue on DSLRs. With little money we could add that feature found in cinema cameras. But, I guess, Cannon won't offer this for a low price. 1DXIII has no issues regarding overheating. R6, instead, for less money, with the same sensor, has this problem. Finally everything is about marketing, about money. I'm happy that Canon somehow answered. It's a shame.
    EDIT: overheating is real:

    Perhaps I'm just a crazy fanboy, but this seems... entirely reasonable and not at all out of step with what I expected? Not only that, but I actually think Canon's transparency on the matter is enormously refreshing? Am I the insane one here?

    I am usually very quick to criticize large companies who fail to meet expectations or pull some pseudo bait-and-switch nonsense, but I genuinely don't believe the outsized criticism of these heat "issues" is warranted. The R5 is not -- and was never advertised as -- a C500 replacement. The spec sheet, even including these high end recording limitations, is more than I possibly could have asked for 6 months ago. What were others who are more critical honestly expecting? (This is not a pejorative statement by the way, I'm genuinely curious -- if you're disappointed by this, what were your expectations?)
