Shocking. Appalling.

And the most challenging situations apply to Johnnie's shoot?

Internal casing views. It looks like thermal pads conduct onto flat moulded surfaces for each chipset, on the magnesium alloy body itself which isn't a good conductor. There is a reason why PC CPU heatsinks are copper or aluminium and even smartphones contain copper.

https://www.eoshd.com/opinion/opinion-canon-r6-and-r5-heat-problems-risk-full-product-recall-class-action-lawsuit/ Looking at the internal circuit layout, it's amazing how many hot components Canon put close together. CFExpress media is almost backed into the image processor. The image processor is surrounded on both sides by what appears to be RAM. Behind that circuit board is the warm LCD backlighting when flush to the body. In front of the circuit is the warm sensor. There is literally nowhere for all the heat to go and worst of all it is centrally concentrated on the most thermally critical piece, the DIGIC X CPU in the centre. Without even a thin copper heat sink or slim heat pipe (like in a high end smartphone), there is no way of guiding the heat away from the critical components like the CPU. It really is no surprise then, if the camera is borderline defective.

Discussion can continue here in one place:

What's the source for the info "new heat dissipation system"? Please link to it.

EH? Clearly these things matter with this camera massively. So why not mention the info? Even the approximate minutes and hours? In order for us to know what his conditions on the shoot were and how long he ACTUALLY used the R6. For all we know, he could have done a 1 hour interview take, then it overheated and couldn't do subsequent shorter takes. Just in effect saying "I made a documentary, and erm, this camera wasn't suitable" is completely useless for anybody thinking of buying the R6 and working around the limitations.

Rep bullshit. On a separate note, let's reduce the number of overheating threads before the forum also overheats 🙂 I'll keep this one open for now, but overheating talk should all go in one place, don't you think....

Please continue from the other threads here. Those threads are too numerous and should be combined into one. Cheers

These rules are here to make the forum as interesting as possible to read for others. If I ban somebody, it will only be be because they repeatedly broke the rules below. I ask for everybody's understanding on this - I only have two goals - to protect EOSHD and my business, and to make the forum a source of high quality camera and filmmaking info. Cheers! 1. Please be polite to other users where possible, although lively debates and disagreements are ok and to be expected! However, when it comes to the site owner myself, I would like you to bear in mind that your remarks are in my house and on my phone screen. So it is especially important not to come here with a hostile attitude to the site owner. I do not wish to see this content in my home and it will result in an instant ban. I do not want trolling at work, or during home hours. 2. Please do not promote your own products without OK-ing this with me first, especially ones which compete with my own at EOSHD. This includes camera guides, colour profiles, LUTs and alternative blogs or forums. If an account is setup for the main purposes of selling LUTs for example, this is not OK and you must clear this with me first. If I like your work I may get in touch and work something out. However I will always reserve the final say for the very obvious need to protect my own livelihood and website. Please do not use your forum activity to take customers away from my own site. 3. Extreme topics and viewpoints relating to communism, baseless conspiracy theories, MAGA and extreme left & right-wing politics are not allowed on the forum. I welcome people of all reasonable political views but I do not accept far left or far right propaganda on the forum. The filmmaking community is largely a liberal art and Trump endorsing views aren't usually welcomed on set, so it's important to keep in mind that the same applies to this corner of the film and camera industry too. Please understand - this is not about political censorship but about avoiding a hostile and divisive atmosphere in the community. And to ensure camera topics aren't side-tracked. It is not so much about politics as about morality. 4. Please try to post original and useful content! Only linking out to other sites or YouTube content will not be tolerated as EOSHD should not simply be a rehash of somebody's private web surfing history. Please try to contribute real-life experiences of camera use, images, actual filmmaking and relevant topics in an original way. 5. Please do not regularly bump your own topics, especially curating your own editorial style compilation of YouTube videos you've found on the web. The forum should not be an advertising platform for poor quality content. A few relevant clips are fine in the context of a discussion. 6. Trolling is forbidden and results in an instant ban. Users with a hostile attitude to myself or my friends on the forum will be banned immediately as first post is moderated before being shown. So don't bother with that. If a user rejoins under a different name to continue the abuse, email, IP address and all meta data will be logged and depending on the situation, legal steps may be taken and law enforcement may be notified about threats, libel or online abuse. 7. Please do not post completely off-topic posts and please keep chat & small talk to private messages! When a topic has a lot of short opinions and off topic remarks, it can be difficult for users to find the objective, factual camera information they came to the EOSHD Forum for. 8. Any account set up for product advertising purposes or spam will be deleted instantly. This can include representatives from camera or accessories companies, who use the forum to promote a product in an obviously biased way without acknowledging the site owner or contributing beyond the purposes of promotion. Carefully disguising this as helping users on a technical level will not pass muster! 9. Fake users are not allowed on the forum, bots are pre-moderated. All spam accounts will be deleted. 10. Advisory: Whenever possible, please to avoid posting URLs in topics to the following sources: Tony Northrup (YouTube), Max Yuryev (YouTube), Fro Knows Photo (YouTube), Cinema5D (CineD), NoFilmSchool, DPReview, 43rumors, Sony Alpha Rumors, Everyday Dad (YouTube) and the DPReview Forums. In my opinion these sources have too much emphasis on advertising, too cozy with camera PR departments, too much clickbait, too much sponsored content, or even feature a hostile competitive attitude to EOSHD. For example the DPReview Forum for years had a ban on my URL, so in response, please do not link there. I won't censor it, I just discourage it.

That'll be the day. Most haven't even got past the denial stage! Sony's overheating was largely to do with the A6300. The A7S II was fine and has been a workhorse for videographers. The A6300 was one quarter of the price of the EOS R5 and very much a mid-range consumer point & shoot / slash enthusiast camera at a stretch. But the Canon EOS R5 is a $4000 professional tool. The A6300 wasn't exactly let off the hook, especially by me. It received a ton of criticism and rightly so, even thought it cost so much less than a professional camera that needs to be bullet proof reliable. I think Canon have made a catastrophic decision, and it will haunt them for a long time.

Except that isn't true. Didn't provide real world shooting times, not even rough estimates. Didn't talk about a real world shooting schedule, in terms of the amount of time the shoot lasted during the day. Didn't mention the average length of a take. Didn't say at what point during the shoot the overheating trouble began. Didn't estimate the resting gaps in-between. Or whether the camera even remained turned on during this time. Didn't say whether the indoor scenes had a lower temp than 28 degrees, due to air con, or other factors. Did not say when the ice pack was applied, how long for roughly, or whether lower ambient temps even made a difference - seems they didn't. But yes, praise away the "great job of providing real world information"! Not reading too much into it at all. Final warning. Agitate me again and you can go and use the DPReview Video forums instead.

Canon President and long-time camera business COO Mr Maeda-san has stepped down for health reasons. The change means 84 year old Chairman and CEO Fujio Mitarai once again assumes the triple role of Chairman, CEO and President until a replacement can be found for Masaya Maeda-san. https://www.eoshd.com/news/canon-boss-masaya-maeda-has-stepped-down-due-to-health-issues/

The production models aren't going to fundamentally change. It isn't a Firmware Optimisation issue. You will not lower the heat generated by tweaking the source code. Outputting 8K sensor readout, processing that to 10bit 422 with a CPU not adequately backed onto a copper heat sink and heat pipe, no fan, sealed body, poorly conducting materials, probably far from the latest silicon process node (7nm) used to make the CPU and multiple sources of heat compacted together - big sensor, fast RAM, very fast CFExpress memory (which is also capable of thermal throttling). It's like saying... my laptop gets hot in games so maybe updating Windows will help. Camera design is fixed, it's done. Besides the pre-production model is but a few weeks behind the final retail camera and 99.9% the same even at the firmware level. There is not the time to fix it before release. It needs a complete redesign of the internal hardware.

Have you actually compared the 8.2K oversampled 4K to any of the other oversampling cameras, such as the Fuji X-T4, Panasonic S1H, Panasonic S1, Sony A9 A7 III etc.? These already look perfect even on a chart. Oversampling from a 6K sensor or oversampling from 8K, there is not a huge difference. In fact the Canon EOS R5 image may even be a bit softer looking in C-LOG. Have you actually compared the original A7S II 4K output on a chart to the EOS R5 4K HQ mode? No, didn't think so. But apparently the gap is huge! 😂 Why the hell would you spend $4k on a camera to shoot 2014-standard pixel binned mushy 4K?! That's because it's atrocious, and it's the reason there were no serious 1D X III rolling shutter tests. Canon is the one handing out the cameras to those they have personal friendships with via PR people. Do you really think any of them have the balls to go for the jugular over 32ms+ rolling shutter?

Much as I'd love my forum to become a one way discussion between social media influencer self promotors and camera nerds, it ain't going to happen. Sorry to disappoint! @Django If it is famous names you want, if somebody like Roger Deakins joined he would actually deserve respect. Why don't you invite some more actual filmmakers on the forum to chat with, rather than falling in love with an ex-store sales rep?

HAH! Indeed. Professional - oh can you wait while I put ice on my camera please, thank you. I'd have kicked him off the shoot. It's a doc that anybody could have done, any amateur can ask to film somebody who wants publicity. People do it thousands of times a day all over the world and it is all out there in all its mediocre glory on the internet. To disguise this effort as some sort of 'giving back' to the camera community, helping people make informed decisions, it's all bullshit, and amazingly people do fall for it in quite surprising numbers. Which is in itself a poor reflection on the state of humanity. Why doesn't Professional Career Man answer my questions if he's such an expert. He knows roughly how long the camera rolled for on a take before an overheating warning and how far into the shoot that was. He knows whether or not the camera was turned on or off during gaps in-between takes. Was it in live-view the entire X number of hours, and how many batteries did he get through? Lastly what the fuck did Canon get out of this? The bad publicity from the article is one thing, and deserved. But zero useful feedback? No timing data? THAT is how Canon end up in situations like this in the first place.

Here we have some much higher quality and more useful information from Gerald. The external recorder situation is as follows: Let's give guys like this their due and not reward the wannabe filmmakers.

Just when you thought the Canon EOS R5 overheating drama had ended, the EOS R6 picks up the baton. But this time, not everybody can agree on what it’s good for. Read the full blog post

Behiri's motto seems to be Professional filmmaking is what you do, not what it looks like!

I tried to tease the basics out of him but he was having none of it. Just the usual Cinema5D c**ty line of "you're just a tester, leave the actual filmmaking work to us"!

Incredible that people will spend $4000 for worse than 2014 image quality.

It looks much worse than the old 2014 Sony A7R II to me The aliasing and softness at 100% crop above is worst-case scenario stuff. How that footage can wear a 4K badge I will never know.

There is so much info missing from the C5D 'review' but it isn't looking good. How long was his average take How long was the average break and how many, through the entire shoot How long was his longest take How long was the average gap inbetween clips When the ice pack came out, how many hours was he into the shoot How many hours was the total shoot?? Was the camera switched on all the time, even when not recording If so for how long How much was indoors, how much outside? Was it sunny? What was the temp indoor? There is less technical and detailed info in the review than in the average episode of The Simpsons
