You are wrong. I cannot legally advertise a product I've made as a professional cinematography camera, when it is in fact a banana. I cannot please my customers or make good business selling something as "8K capable" when it isn't. To say every company does it is just not true. In fact if they tried it, they'd be on wrong side of the law and wrong side of their customers. Can you imagine the fury if your iPhone started overheating 1 hour into the day and you had to turn it off for 30 mins? I am very baffled as to why you think Canon can get away something similar... because it's a camera. No, they advertised it a certain way, and even the late admission of heat limited recording times is misleading because of how the camera behaves 10-20 mins after being switched on, or 30 mins into a stills shoot.

The camera seems to completely ignore ambient temp It carries on ticking the clock down... 15 mins, 10 mins, 5 mins... This is after just 1m 3sec of 8K recording, the rest of the time the camera was sat idle in live-view (8K enabled in the menus). The video mode you enable in the menu seems to set the timer. And after that not even liquid nitrogen seems to make the counter go up. All seems very fishy to me. I was down to 5 mins after applying the ice. To the touch the camera felt like an iceberg from top to bottom. I even had it on a bag of frozen chips at one point, but realised the chips were melting and I wanted to eat them for dinner the next day.

Maybe I should shut up now and let DPReview take over. Let's see if they take a lead on this issue. If they don't, we know the score. Ah, in fact we already know the score so I needn't bother! And the fact that Jordan is an ex-salesman tells you a lot.

It is indeed. But for Canon to fix this they might have to admit they lied to their customers, which isn't a great look to be honest https://www.eoshd.com/news/chinese-user-modifies-canon-eos-r5-to-improve-heat-management-but-finds-artificial-firmware-time-limit/

Correction! "The ability" in terms of maybe for 10 mins, during the first hour of a shoot, but then after that no ability whatsoever to record high quality video. It's no excuse at all. Canon are using 8K RAW as a marketing trick to sell more cameras. Have a think if this kind of dishonesty is what you want to be seen to be defending. Even if customers come to terms with the fact that they have mis-sold to and lied to by Canon, and they come to terms with the pixel binned 4K 30p maximum capability for reliable shooting, the damage to trust in the brand is immeasurable. The very fact you are using an EOS R camera as a B-cam to C700 is how the R5 was sold to us, with Canon's press release at launch explicitly mentioning that the camera would be comfortable on C300 III productions as a high-end 8K RAW video capable camera, with oversampled 4K and 4K/60p/120fps. There is more to this than marketing. It may be that they are entirely blameless. It could be that the camera was supposed to work far better than it does and an unforeseen manufacturing problem or design issue held it back. There's all sorts you don't know and can only speculate at. Yeah, well as one of those reviewers, you can thank me. You should really read the main article before joining the forum with your BS fountain. I said I bought it solely for the purposes of reviewing, testing and finding out the truth first hand about the overheating issues. You can apologise to me in your next post or you can fuck back out the door, up to you. Great!! Leica50mm has the solution! Let's hear it then...

Thanks @androidlad This is the kind of post we need more of.

I'd like to know what's going on there.

Do you have anything constructive to offer or just more of this? Getting a bit bored of it now.

Did you even read the article? I suggest to do that!

I see, so it disabled 4K HQ when you pull the card? And it never outputs anything better than pixel binned 4K via HDMI? Need to do some testing here. Looking at all these YouTube thumbnails looks like I need to practice my UNHAPPY FROWNY FACE for the next article.

Regarding a campaign requesting Canon to fix it I am all ears. First step should be to reach out and persuade them directly, allow them to realise how seriously their customers view this problem. The petition might be useful to show to Canon in terms of number of people they have upset. If that fails then the second step should probably be a class action lawsuit. Not sure a petition will change much in that situation but a lawsuit would.

CFexpress doesn't seem to make a difference. Yes they get hot, yes they can even throttle read/write speeds... but my camera crapped out on me with an SD card inserted only, in Wifi menu. So go figure! Maybe Canon forgot to stop the Cripple Hammer Clock in the menus? 🙂

Yes, good question. Why did it get released? It is baffling. Management would have known. Engineering would have known. Testers should have known - they tested it! Reviewers soon knew. I found out within an hour that it overheats sitting in the menus with 4K HQ set to on and overheat control set to off. So it is very confusing to me why it is on shop shelves marketed as a professional C300 III B-cam! You can speculate and make up your own theories as to why Canon thought they could get away with it, and whether it is intentionally crippled, or buggy, or just incredibly broken at the fundamental LSI level.

I think as Gerald showed it is just dropping to a pixel binned non-HQ output in HDMI mode. That isn't heat limited.

It is very strange But if you remember Gerald and Richard's live-view / stills shoot tests where 1 hour in the camera was at 0 mins for 8K without having recorded a single minute, it's a similar thing to what I experienced in the Wifi menu. The menu is just an overlay and the live-view feed is still likely active and being processed, ready to display immediately again when you dismiss the menus with a half press of the shutter. I think the 4K HQ option gets deactivated when the Ninja V is connected too, which may explain the extended record times to that, because it is pixel binning or even line skipping to the HDMI monitor.

Results of the first 1-2 hours with the camera out the box: https://www.eoshd.com/news/i-bought-a-canon-eos-r5-and-it-overheated-in-the-wifi-menu-also-a-look-at-potential-solutions/ I see. Something to test then. I wonder if Atomos will be honest about it as well and say that it's pixel binned, not "high quality"!

At the weekend I bought the enigma that is the EOS R5 for myself. Foto-Meyer in Berlin were able to find me a rare unit. A huge thank you to them! What all EOS R5 owners have in common is that they have paid a lot of money for a professional video tool. We pay the money, we get to decide what happens next, and I'll be reaching out to Canon and making this clear. We need to ask them to work on a solution for overheating. It's worse than you can possibly imagine. Just need to get something straight - my purchase is NOT an endorsement of the EOS R5. I bought it purely to cover the camera on EOSHD and to help work on fixes for the many issues this camera has. It is in no way a dependable tool for 8K, RAW, oversampled 4K, 4k 60p or 4K 120fps in the state that it's in. At the very maximum it is a pixel binned 4K 30p camera similar to the Sony A7R IV with the benefits of Canon's colour science, 10bit codec, top LCD and better ergonomics. Actually that doesn't sound so bad does it?! But this is not how it's sold to us - it is supposed to be a $4k all singing, all dancing, cutting edge 8K/4K video tool and that's how it should perform in the real world.

All the signs point to it being unintentionally crippled this time. It's astounding how broken the R5 is. I now have mine and had it overheat in the Wifi menu. It was just sitting there on the desk waiting for a connection. And the cool down periods are incredibly long. There are signs Canon knew about the problem late on and tried to patch it up with a few features. The overheat control option reduces the live-view quality so the image processor doesn't have to deal with the 8K torrent of data coming off the sensor. The live-view feed seems to be active all the time even when camera is in the menus which is why mine overheated in the WiFi menu with not a single second of video recorded. Well ok... 6 seconds to be exact! Without "overheat protection" turned on in menus, it basically cooks itself doing nothing.

Are you a moderator? No.

I don't think the Jinni thing is exactly RED's proudest achievement is it @Emanuel? In the new video, their lawyer even admits JinniTech suffered as a wronged party and offered him some vague 'lets do business' line - It was pointless for RED to fight this battle. What comes to light is disturbing. Now it is JinniTech suing RED rather than the other way round, what happens if he wins?

Really doesn't look any better than the old 8bit A7S II to my eye. What am I missing?!

Can somebody summarise the latest info?

What's the source for this? I asked B&H and they replied they had no date from Canon at all.

These are unit sales right? Unit sales do not tell you about profit or margin. You can sell a smaller quantity of more expensive high margin cameras. There is a lot of money left in the camera industry. If a couple of soulless corporations leave, then I won't shed many tears to be quite honest. They have put shareholder profits over cameras at every opportunity. And if the quality of images from the Huawei P40 Pro does suggest the camera industry is heading back to making tools for a niche of artists and professionals. I'm fine with that to be honest. Sigma, Fuji, Panasonic... the thinking man's cameras.

Media alert! All EOS R5 owners will get a free R5 shaped box delivered on Monday. Canon look forward to all the creative ways users will find to wrap the camera body and send it back to Japan.
