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?

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.

Thanks for that. So it does need quite a bit of space to move out of the way after all. Solution would be to have the camera be wider, with larger back screen, and slide the internal filter to the right towards the grip.

All a lot more sensible specs than 8K.

And boom...I see they locked the thread! (DPreview) 😂

New blog post with the latest test results. https://www.eoshd.com/news/the-canon-eos-r5-overheating-impact-on-different-types-of-filmmaking/ The 4K/120p goes for 15 minutes. What I need to test is whether you can shoot 10 seconds here, 20 seconds there, with short breaks in-between for the duration of a shoot. Because if that produces too much heat we are truly stuffed.

When it dies in the middle of a shot will the first thought be "I am glad Canon pushed the camera industry forward" or will it be "why did I spend £4000 on this thing which Peter McKinnon said was THE GRAIL CAMERA"?

Is that a weird menu bug or what?! Total rec time: Zero! It's a new marketing feature for Canon - 8K 60p for zero seconds! YouTubers will go wild for it.

Indeed, as a crash cam - it'll probably have to roll for a good 10-30 minutes before the action is initiated. There will be a point where it's out of reach for the operator, and has to be rolling. But the rest of the sequence might not be set up and ready to go yet. The crew can't be bothered to make sure the EOS R5 on set is the last to roll. They will just use a different model. Simple as that.

I don't agree at all. Even when you edit an interview down to 10 minutes, conversations can go on for much longer. To get the required information, the subject often has to be conversed with and prompted. Documentaries a case in point. The multiple cameras just makes the situation worse. If you have to keep stopping, restarting and syncing 3 or 4 cameras every 20 minutes, that is seriously distracting - and not just for the crew but for the subject as well. When it comes to the edit all these files will be broken up from multiple cameras into 20 minute chunks and it makes the edit harder. Canon probably realise all this - they still want pros to buy the Cinema EOS cams instead. Even though the EOS R5 is £4000!

I don't really know what any of that means but the "variably" stands out. That the recording limits are variable is my worst nightmare! At least with a set and certain 30 min limit you know the score on a shoot. You know how much you can roll, and when to take a break. With it being obviously influenced by ambient temperature, often the limit could be anything between 10 and 30 minutes. There is no predictability. It's a disaster.
