I completely agree. Canon thought the 8K and specs would outweigh the drawbacks of overheating problems. We'll see however if this harms the Canon brand image for reliability, and how many of the target pro customers (EOS R5 in particular) return the camera within a month because they can't get through shoots. It might end up being a non-issue, or it might end up hurting sales. By the sounds of McKinnon though he is having a lot of problems. We'll see. And yes at least they were transparent about it and made the recording time figures available.

I could buy one its own plane ticket to the UK, have it accompanied by a minder in seat next to it, buy a fire extinguisher just to be safe and still save £500 on the shop retail price 🙂

It's not even a campaign Simply about reporting the facts None of the major coverage initially mentioned any overheating issues. People were pre-ordering the camera under a false pretence. So I had to put the facts on the blog rather than have that info stay hidden in the CVP video. You seem to be suggesting that I should shut up? It's $3900 + tax. I expect it to do what a $3900 Panasonic S1H does - active cooling, 4K 10bit 422 unlimited record times. 6K or 8K is just a bonus. The RAW file sizes are unmanageable for longer record times so the overheating in that mode is only the secondary problem! Of course, you can produce lovely work with the EOS R5. It's will just be a shame about the moment on that shoot where great stuff is being captured up to the point where NOTHING is being captured because the camera got too warm.

Calm down gt3rs please. The forum has just about become tranquil again after I removed the troublemakers. Don't become the next. Nice perspective. Yes there are two sides to the coin On the one hand Canon pushed the envelope and finally gave us the specs we wanted. On the other hand I wanted a reliable camera too, and there's no excuse for not putting a proper heat sink in there - it is a bit like Intel shipping their most powerful flagship CPU without one. https://www.eoshd.com/news/heat-management-what-canon-can-learn-from-the-panasonic-s1h-and-sigma-fp/ The Sigma Fp and Panasonic S1H lead the way in that and show what's possible. So a major oversight from Canon there. I think there will be a fair bit of denial until the camera actually gives up during a shoot, then people will reconsider how practical it is to use. We have to test it for ourselves at the end of the day. If I can shoot a bunch of takes in the highest quality 4K modes no longer than 5 minutes each and keep going one after the other without heat build-up, I may like the camera more than I do at the moment! I think it's worth waiting to see what the Sony A7S III is going to be like as well. So I may not jump on a pre-order with the EOS R5. Besides as @BTM_Pix pointed out the other day, it is about £1000 cheaper in Japan so may as well go there on holiday for one than pre-order in the UK.

Smartphone can process the same amount of pixels (8K) and encode to same codec for $700 Xiaomi Mi 10 Pro

The last one where we had to find the best camera under $200 was a hoot Best technical image was the 4K GX85 but the videos also had various levels of ingenuity and creativity. I am open for ideas for that the next challenge could be 🙂 Best low light camera for under $500? Most cinematic look for $300? (Regardless of resolution) Music video shot with one prime challenge? Let's settle on a theme and see if we can get the next one going.

Canon want you to buy the EOS R5 for that Canon want you to buy the C200 for that Canon want you to buy the C500 II for that and all the rest, really is the last step up, promise. Have you considered the 1D X Mark III?

Client doesn't care if you miss an entire shot because the camera has steam coming out the card door?

I think they have work to do

Yes I probably will enjoy it for that but I have to think not just about myself when I write advice and commentary in blog posts - there are a lot of people who need the longer recording times and predictable reliability, like I described for the shooting situations in the recent post. As for ergonomics I don't feel particularly inspired by the EOS R5 looking at the design, finish or materials, but it does seem to have a decent control layout. Sony are not too bad now though - the A7R IV was a good step in the right direction and they just need to sort the menus out now.

Will be very interesting to see if the EOS R6 will also get a firmware update - compressed 4K RAW anyone? That camera is shipping a lot later - End of August. A7S III end of September. EOS R5 comes first end of July.

It mistook it for AndroidLad.

Suuuure. Canon 1D X II has 4K60. Doesn't overheat.

Doesn't look too bad to me.

Shall we make a list? S1H GH5S GH5 GH4R X-T4 1D X Mark III / II 1D C And so on

4K 120fps full pixel readout? Yes please. Sounds like a much better option than EOS R5.

The Sigma Fp records internal RAW and is the size of 2 decks of cards!

Same overheating and rolling shutter problems to the 4 years old $1200 Sony A6300.

The Canon EOS R5 works in mysterious ways. Canon chose to implement 8K and 4K/120p on this camera knowing that heat build-up will make for some short recording times. This was a risk, because the perceived hit to reliability can generate a lot of bad publicity. What was Canon thinking and what else does the camera offer for when more reliable recording is needed? New blog post: https://www.eoshd.com/8k/a-closer-look-at-the-canon-eos-r5-lower-quality-4k-mode-to-avoid-thermal-cut-off/

Top Gear and The Grand Tour - two of the biggest TV shows on the planet, use a GH4 / GH5 inside vehicles.

Thanks for this. Well... It will be interesting to see how the quality differs. I am expecting the pixel binned 4K modes to be roughly similar to the A7R IV, but with a 10bit codec, or the Leica SL2. There will be some moire and aliasing. But might not be too bad. This is one way to get away from the hot potato 4K HQ mode

Plus it runs off a GH2 battery. Incredibly efficient processor and sensor. Quite amazing really. The EOS R5 could learn a lot from it.
