p.7 #1 · R5 stills overheating

One more report of overheating.


You must not be following this thread. That's the same anonymous person's comment linked to in several previous replies. The one I noted as being anonymous with lacking information.

This shows how people can double anonymous artificially. One person re-posts, then another repeats saying the same is "another".

And like a few anecdotal notes on the internet, there's not enough information given. The post didn't actually say it was overheating or that any camera message displayed. It could have been the battery running down, regardless what temp was mentioned that day. Sounds like it was not their camera. Had somebody placed it on dark surface? Because something like that could be hotter. Was a grip used, and secured properly, or not?

And .. is the anymous person telling the truth, or posting an anonymous lie?



The guy has been a member at CR for 2.5 years with 120 posts to his name. Its not like he just joined today and posted this stuff. He owns a lot of high end Canon gear so has no reason I can see to spread a false rumour about a new Canon camera. We can never know for sure, but sometimes you have to look at the whole picture of who this guy is from what information is available and make a judgement call. My impression is he is legit and telling the truth.

Regardless, his and Andrew's reports don't concern me much. But this is the topic of this entire thread so worth noting a 2nd occurrence of a similar stills only shutdown.

What else is new?

The Blind Brand Loyalists can't handle anything negative about their new toy they just dropped a lot of $$$ on. It happens with every release from every company. I get a kick out of it every time. I get an even bigger kick seeing the same BBL start to come around and admit to the faults the realists were talking about 4 years ago right around the time the next product is to be released

Like I said, the post doesn't specify whether the battery went dead, or several other reasons. So even if the guy is for real, it didn't have enough info for people to base a decision. I still prefer some non-popular youtubers who show their real face and share more complete videos. Especially the ones who reply to further questions.

This one was straightforward and connects enough dots to help a purchase decision.

Am I the only one that sees all these overheating reports and really wants to see some next level weather sealing tests from someone like Kai Wong?!?

If the heat really is getting trapped inside this must be the best weather sealing on a FF Mirrorless body to date!

Don't own the R5 myself but I just checked the EXIF of an R5 raw I downloaded online and Canon includes the internal camera temperature in the metadata. In advance of sending it to CPS I would do a controlled experiment where you start the camera cold and leave it on (disabling any auto-power off setting), taking a photo every 10 minutes for say an hour or so. You can then check the temperature in the EXIF of each image and supply that data to Canon, along with the ambient temp of your room so they'll have a point of

Thank you very much. This is what I got from those shots:

shot 001 50c 
shot 050 61c
shot 100 61c
shot 150 63c
shot 200 65c
shot 250 68c
shot 300 66c
shot 330 74c
shot 380 75c/167F
shot 400 73c
shot 450 69c
shot 500 66c

These are almost all of the eagle in the tree posted in the R5 pic thread. When he would move at all I would fire a few seconds of shots to get him jumping or another pose. Most likely the temp drop was when I went to the rear screen. I'm pretty sure I won't say anymore about this in public.

Wow, those temperatures seem really hot. Those are temperatures I would expect to see on a video card or CPU running full tilt rendering video or Folding@Home. Yikes, sure would like to know where that temperature sensor is located. Hopefully those readings are from inside the Digic X chip. If the temperature sensor is on the circuit board or some other general location, that means heat producing elements are much warmer.

That is actually not very hot for CPU. Macbooks routinely run at 100c.

Really?? That seems awfully hot. I don't have a Macbook, but my Predator and Alienware CPUs both normally stay between 50-65c, even at heavy load.

Not trying to be argumentative, but the latest high-end Intel Core i9 Extreme CPU has a max temperature limit of 86c. The chip physically turns off at 86c to prevent damage. Prior generation Intel processors were thermal limited to the low 90's.

Thanks for confirming--I thought I was going crazy over here!

If someone (including Canon) can come to market with a decent cooling adapter, I'm guessing these temps would come down quickly. Tilta's offer seems intriguing, but no word on cost or delivery. I'm 99% stills, but would still prefer to run electronics as cool as possible.

Actually those temperatures are not as bad as they might look considering they are from a small tight weathersealed body without any form of internal cooling mechanism we know of.

Those are high end desktop / workstation chips. You can see that the CPUs frequently run at 95+C regularly in MacBooks.



You are comparing liquid / large air hsf cooled chips with laptop chips which are designed to overheat and then throttle regularly.

Keep in mind those Intel/AMD CPU temps are internally measured within the chip, whereas the temp reported by Canon in the EXIF is likely an internal-chamber ambient, so the two temps likely aren't comparable (ie, the CPU temp is much higher than even the immediate ambient area around it).

Does anyone know what temperature they report in the EXIF data? It could easily be the image sensor temperature. IQ suffers significantly when a sensor gets warm. It doesn't take a very high temperature to affect IQ and the image sensor would certainly have an integrated thermal sensor. Every processor (and most other ICs) I've ever seen have temperature sensors built into the silicon. Measuring air temperature inside the camera would seem fairly pointless, and costly. To do it they'd need a temperature sensor chip thermally isolated on it's own circuit board somewhere inside where air is able to circulate around it. There's not much room for that, and it's just extra stuff that's not needed when every "chip" they're already using would already have an integrated temperature sensor.

There is no substance to that claim of where the temperature is being measured from. Canons DIGIC processors are based on ARM designs which also include internal thermal monitoring. Nobody knows from where that temperature is being pulled. Since it’s 76c at times, it is much more likely measured internal to the chip and not an air temperature surrounding it.

Exactly. If the air were 76°C, the CPU would be fried without throttling.
However, there may be more than one temperature measurement and/or there is a high value for hysteresis that explains why it takes so long to reset.
