I am reporting extreme overheating just shooting stills. I had the camera shut down and the Canon battery that came out was extremely hot. This was a 90d Canon battery so not a high discharge version that ships with the R5. I am going to guess most stills shooters will want 3 spare R5 OEM batteries just to shoot stills for fun. For work I would believe many more.
Any chance this is a defective one? Have others replicated this? I'd think it would still be under warranty. Maybe send it in.

So here's an idea I just thought of: since the cards get so hot that Canon had to put a warning inside the card door, is there a way to attach a heatsink/pipe in a way that it would insert into a card slot without shorting it? Maybe dummy pins connected by thermal pads? Being so hot, drawing heat away from the card slots should be great for directing heat out of the body. Then a fan could be added. Not great for hybrid work without a bit of finagling, but fine for video-only.
A concern: I don't remember how my EOS R's card door operated, but at least my 5D II disables the camera when the door is open. Is this true of the R5, as well? If so, a workaround (dummy door frame, cutting a hole in the door) would be necessary to get the above idea to work.
Another concern: does the camera need a card inserted to record video externally? If not, dual heatsinks/pipes can be installed for twice the cooling. That, along with offloading a good amount of work to the external recorder, should remedy a lot of the shutdown situations...Show more →
Maybe tape a really thin piece of copper or aluminum to the card? Not sure how much room is in there though. Maybe tape it on the other side of the contacts or something? Or at least far enough away from the contacts.
Not sure on the R5, but on the older bodies you can press the little switch that tells the camera the battery door is closed and maybe even pull the battery door completely off, if the switch is pushed, IIRC, and run the camera normally. You have to pull the battery door off for a grip
I've shot hundreds of football games in Australia on 1Dx and 1Dx2 bodies, shooting JPEG, never had any issues. My first game on an R5 (borrowed from Canon CPS) and it overheated and stopped firing, at a crucial moment. I had to turn it off and hope it cooled down. From then on I shot very sparingly, but can't vouch for R5's as a sport body at this stage.
Did you do a reset of all camera settings including custom settings? I have 2 R5's, and never have overheating in stills mode.
What will cause overheating are the 3 high output video modes, 8K, 4K HQ and 4K 120 FPS. The camera has separate presets for stills and video, C1, C2, C3. If the C3 for video is one of those high output modes, it is in standby with that setting, and will overheat pretty quickly. Make sure the C3 is not set or set it to another video setting besides the 3 above....
I haven't even looked at video settings, I used C1 only which was in stills mode. I shot another game of football yesterday and it didn't overheat. I did notice it getting slightly warm, and the cards slightly warm, but on Friday the body and cards were much warmer and it eventually stopped firing.
I was shooting in-doors so it wasn't in direct sun.
Just for info, there is no high discharge battery for these, just a higher capacity which means it can last a tiny bit longer. I think it is only about 200-300mah more, so not so significant. The battery isn’t contributing to this at all.

Maybe like my body it shipped in a very hot vehicle and the camera started off very hot inside.
Unsure about yours, but this one belongs to Canon CPS here in Australia, so they wouldn't have sent me one with known issues. I haven't purchased, am just trying it out in the field. My 1D bodies need upgrading so am looking at options.
Apart from this issue, which I do consider major, I love the R5 so far. If I had 2 R5's I think I could have swapped bodies when it overheated, but the fact it happened makes me unsure about implementing them into my kit.
I’ve had my 2 r5s since launch. One from bh and one from Texas media systems. I’ve seen the video overheat since I’ve had them but today I had my first stills over heat on the latest firmware. I was at the zoo today, 100-500 rf on. It was 64f outside, I had the camera turned on and off between exhibit lines for the most part. I took about 200 shots or so, and I saw the camera overheat warning after having been in the zoo for 2hrs. The only other time I had the camera on and off for such a long period was in the winter outside. Needless to say it was pretty shocking.
The R5 gets uncomfortably hot in normal still shooting. No warnings or apparent operation changes, just user comfort.
Yesterday, I was shooting the little kids playing in the backyard. Mild temps (75F) and filtered sunlight. In 50 minutes I shot 355 images (~7 shots per *minute*) on H and L with bursts longer than 15, and few more than 6. No breaks longer than 5 minutes so shooting was spread out.
The grip at front and rear gets warm enough to touch that prolonged sustained contact is uncomfortable. Not painful. But warm enough so that switching to the vertical (I use the battery grip) is a cooling relief.
I recall the same thing earlier this weekend shooting 198 images in 94 minutes with the same amount of occasional short bursts. Now, I'll pay closer attention and even try to image the heat with my Leopold thermal imager.
Maybe it's me. The metal rim of my insulated Yeti coffee cup gets uncomfortably warm to sustained touch even when the coffee is drinkably cooled by milk so that I move my hand to grip at the cooler bottom where it gets some relief.

What brand of CFExpress card are you using? Some cards generate a lot of heat even when not being used. Others have much better heat management. I would guess uncomfortable heat would be coming from a card with poor heat management. Is your card really hot if you take it out of the camera when the grip is getting hot? If you haven’t checked that, have a check next time.
I know this is an ongoing post, but I use a Delkin Power 256GB card (green label) and have taken thousands of shots during games with weather ranging from 50 to 85+ degrees and have never had the camera overheat, nor do I remember ever seeing the overheat warning. I shoot RAW in ES, with a backup JPEG written to the SD card (2000x)
In fact, I remember a lot of people claiming that their cards or card readers would get hot during file transfers to the PC. I can say that my card barely gets warm during the transfers and the Delkin card reader barely feels warm at all when I touch it. (cooler than my forehead)
I did use my backup card once to test it and it got significantly warmer after download to the PC. (ProGrade Gold, 256GB)

It is interesting to me that you are listing two name brand cards so slow they won't record 8k. Not only that not even 4k 120fps. This is from testing those two name brands 128GB in my R5. Cards that slow not getting hot isn't all that surprising. In another thread a guy said to watch it buying off brand cards. I say to watch it buying name brand CFexpress cards.

Maybe you should pull your head out of wherever you actually had it when you wrote your response and actually look at the manufacturer's website where they claim that their cards are not only approved to work in the R5, but that they will record in 8k. I specifically said 256GB cards, which if you look at the various websites out there, the 128gb versions of these cards were rated slower than the higher capacity cards. Maybe try reading next time..
I was shooting dance about 6 weeks ago and doing high volume. The R5 showed the early heat warning icon but never stopped. I did shut the camera off for the 30-45 seconds between dancers and nursed it along for several more hours.
Just for the record if this helps anyone. I've been using the 128GB SanDisk Extreme Pro CFE since day one last July and I've not had a single overheating issue in camera yet. Even after doing some 4k/120 footage on the original FW.
The card does get hot such that if you yank it out after a few hundred shots of various burst shooting it is almost painful to pinch tight between your fingers and I'm pretty sure it would burn your lips if you were to clamp it between them tightly. Not sure why anyone would do that, but just using that as an example/reference point. It also gets hot when offloading images onto my computer using a Prograde CFE card reader. I will often leave it in the reader for days until I need to put it back in my R5 and even just sitting in the reader idle it's warm(ish) when I yank it out.
Yesterday I shot 995 images in the span of about 30-45 minutes at a graduation ceremony and for the first time since I first got the R5 last July, I noticed I could feel the body/grip area getting warm.
But again, never a single heat issue.
I'm not sure why Sandisk seems to be the brand to hate, but I've never had a single issue with the Extreme Pro cards in both SD and CFe form factors. Knock on wood.

Imagine that, I just shot over 5 minutes of 8K 30P RAW without issue. I stopped it because it said I only had 7 minutes record time available before I hit record.
