Bring it on. Internal 10bit ProRes 422 (HQ and LT) GH5S oversized low light sensor. Next gen of IBIS Phase-detect AF. Under $2k. Now THAT is something to look forward to. Forget the £4000 fancy pants hand warmer.

LOL Do you think Canon's marketing would tell you?! It's buried deep into the CVP launch video around the 23:00 mark And comes from manufacturer tests with the actual final camera. "CANON have given us information on how long we can expect to get out of this camera"

"Little issues" Is it just me or does the information I posted on the blog post indicate a complete show-stopper of an issue? Even a music video shoot can take for hours where the camera is constantly turned on. One take after another. I can see the overheating problem happening then too, about an hour into the shoot if the camera has been busy, and not just in 8K. The oversampled 4K and 4K/60p are a problem too. The heat build up from multiple short clips will most likely be similar to the continuous recording issue. It was with the A6300. So I'd highly recommend seeing if it is up to the job before committing to it and selling RED gear. You'd expect for £4000 the Canon would provide a bullet proof professional 4K camera - it's what we expect. But it seems they forgot the bulletproof bit this time. Bit of a u-turn hey? This time it's the Canon Cripple Flamethrower! FEEL THE HEAT

Sounds like you're the one with wild speculation that it's the sensor and not the processor! All I know is that a smartphone can encode 8K in H.265, and that it is the most computational demanding task in the camera. The sensor readout for 8K can also be done in a smartphone form factor. The EOS R5 has no excuses for not properly managing the heat.

The guy probably peeled it off "Nothing to see here!" BUY IT NOW

It's hilarious. For years Canon have been the conservative ones, telling us they are not doing this or that for reliability reasons or waiting to get it bullet proof. Holding back on video specs to avoid reliability problems has been the Canon mantra! Then they do a complete U-turn on reliability just to put an 8K badge on the box 😂 The EOS R5 is a pro's camera. It isn't a $1000 A6300 toy. If it lets you down on a shoot that is a total disaster and something no pro would consider working around. How would you work-around it anyway? An icepack? A nice breeze? Put it in the same bucket as the lobster in the catering tent? I think some people are in denial He hasn't even used it yet

Nitpicking? Don't shoot the messenger! It's hardly nitpicking if the camera goes off in the middle of a shoot is it? What happens if you lose a shot and have to down tools for 10 minutes, and then can only go for a few minutes more before the same happens again? How in any way is that fit for purpose professionally or for paid work? And for live stuff, documentaries, interviews, it's a complete no-go, even in 4K. I'd much rather have a fan in there like the Panasonic S1H and know it is fit for paid work, or even Netflix. Can you imagine the EOS R5 getting Netflix approval, only for the entire production to be downed countless times in one session due to the overheating problems?

Will it be shot in 10 second chunks in-between 10 minute tea breaks? 🙂

Smartphone H.265 encoder / CPU are off the shelf components and not even expensive. Look at BOM cost for a Samsung S20. Nothing to stop Canon from using latest 7nm node manufacturing if they wanted to. The EOS R5 overheats because it is not the latest cutting edge silicon. Frankly, for £4000 it should be!

Dude it doesn't matter if you can't shoot! Dead camera on set. Dead camera at wedding. Excuse me priest! HALT the ceremony! My EOS R5 has overheated!

S1 / S1H with 180fps full frame anyone?

Did I miss something and the 4K/24p can have oversampling turned off? Because it doesn't look like that's the case. The non-oversampled pixel binning modes are reserved for achieving 4K/60p and 4K/120fps slow-mo

Surely you should get a better understanding of how CPUs and hardware H.265 encoders work. The H.265 encoder applies the same complex compression formula to the same number of pixels, be it with 8K in a smartphone or 8K in something else. H.265 is basically an iPhone codec. It isn't ProRes! It remains a possibility that the EOS R5 sensor is the limitation, as a hot sensor has greatly increased readout noise. But usually the mainboard LSI, RAM and CPU and the hottest and most power hungry areas in a mirrorless camera.

The overheating information comes from a very good source, who tested the camera. CVP in the UK. Are you saying I should sit on this and not give it any attention? Not sure how that serves anybody. I have criticised Canon that's true... And finally they bring very good specs on paper to the table. But if it isn't fit for purpose on a shoot or on a set - how is it innovative or groundbreaking then? I can claim on paper to be the first camera nerd to go to the moon and set out on the journey tomorrow from my back yard but if the rocket can't get off the ground, there's not much groundbreaking about it is there? "Under market price" not sure about that - It is top of the market pricing for a full frame mirrorless camera with only 3 that are more expensive (one of them is a Leica). In terms of an 8K cinema camera yes it is cheaper than a RED. But it does't work, does it? So the mission to the moon is not accomplished.

Rolling shutter isn't on all cameras, some have global shutter! Here is a £550 smartphone that shoots 8K H.265 in a much smaller chassis https://www.amazon.co.uk/Xiaomi-128GB-Twilight-Grey（UK-VERSION）/dp/B08814LC74/ref=sr_1_2?dchild=1&keywords=xiaomi+mi+10+pro&qid=1594321255&sr=8-2 Why is that image processor not overheating? The R5 is a brick in comparison, with space for potential solutions like heat sinks, heat pipes and more space for the electronics. So why doesn't it work? Plus it is £4000 and at that price reliability is vital.

He then says in next sentence that he hasn't had the chance to record for a very long time 😂 And that Canon hadn't put a recording limit on it. Which isn't true. Besides it's the usual marketing video, so he ain't saying what modes, how long he recorded in 8K and 4K for, what the ambient temps were (looks fucking freezing from the location) or any other meaningful info that would have helped users to know the score. Typical hype piece.

Bit like the EOS R5 sensor. My point is... doesn't matter how many cameras you have round your neck during a wedding if one of them stops shooting in the middle of a magic moment. The shot is lost and you don't get to rewind the wedding or ask people to repeat stuff for your B cam.

For years Canon have been saying this is why they don't push the video specs to the limit. Reliability is key, blah blah! And they suddenly do a U-turn for marketing reasons!!

You can only go on average 10 mins longer in the 4K HQ mode. So that's not good either. I think I'll get the EOS R6 instead or wait for Sony

It's not about having just one camera - two, three, A and B, all fine... It's about getting through a take! Which you may not be able to do with EOS R5. So what's it doing on set at all?

No anamorphic but the image may stretch if you reach 30 degrees C!

Magic metal heat pipe. If you look at laptops they have copper heat pipes to move heat out from the critical components and towards the edges of the chassis where there are radiators, vents and fans. Not much magic about it, it is standard practice in the electronics industry. Canon for whatever reason did not bother to implement the required cooling on the EOS R5, likely to keep size, weight and cost down. Also, with it being weather sealed, a fan and vent is a tricky thing to engineer. However the Panasonic S1H managed it without compromising weather sealing much. So the camera randomly shutting down in the middle of a very important take is fine then? "Hey we lost the shot!" "But that's ok" "Let's switch to that ALEXA waiting in the corner!" Who runs a production like this?

How can anybody trust it for paid work with this problem? It is unworkable on set. Imagine telling the entire crew and actors to go and sit down with a cup of tea for 20 minutes while the camera cools off? No wonder Canon does not consider the EOS R5 specs to cannibalise the Cinema EOS series. This guy's reply said it best:

So much clutter on that image. How does anyone shoot like that?

Did you read the article? The 4K/60p and 4K/30/25p/24p overheats in a similar way to the 8K. Instead of 20 minutes it is 30 minutes. Once the overheating warning comes on, you're basically screwed. Shoot over. You have to wait 10 minutes and then the 30 minutes cap becomes 10 minutes! This rules the EOS R5 for a vast array of work. No interviews. No wildlife. No live events, no weddings. And we have yet to see if the overheating warning comes on during normal sustained use without long continuous takes. If we shoot in 10 second bursts but leave small gaps in-between takes, will the time add up eventually to 20 or 30 minutes and the same heat situation rear its head? I would wait to see what Sony has in the pipeline. Overheating cannot be ruled out with quick successions of shorter clips either. As was the case with our famous friend, the Sony A6500.
