LOL I have ignored him since yesterday. Stalkerish and deluded type, guzzling that company kool-aid.We get it, you are the authority on what the R5 can do and when exactly it overheats or not, and everyone else is just lying to get clicks. Yeah, not gonna reply to the rest of this as we're going around in circles.
Let me start by saying I am not discounting this use case, but I will say how are people solving this issue today? If they are using Cameras without the higher quality modes like the EOS R they are simply recording the event in the mode that works. I would argue the R5 has modes that just work. If Canon unlocks 1080 120 or 240 that is not thermal limited they are giving that same EOS R wedding shooter another tool. I wish 4k 120 was not thermal restricted cause this will be where I make money, but since I have been making money with the R's CRAP 720 this is going to be a joy
So many simple reasons.
- The R5 body is a LOT smaller than the 1DX3, guessing you have not seen a side by side. It is smaller than a 5D4 and even a 6D
- There is no evidence the R5 is not sealed nearly or as well as the 1DX3- it is fully weather sealed. Any differences are going to be completely insignificant thermally.
- 1DX3 doesn't do high bit rate video (4K120, 4KHQ and 8K)
- 1DX3 has a much smaller sensor resolution which is faster to read out so less heat generated per read cycle.
- IBIS requires floating the sensor on a suspension without a large heat sink mass, so cooling is harder.
- Electronic viewfinder and screen running all the time on R5, more power.
Thanks.There are lots of reasons why nobody has reported issues with the 1DX III, not least of which it doesn't shoot 8k, nor 4k 120, probably because there is no way Canon would push their 1 series that hard with untested (put to market) tech. But the 1 series also does not have IBIS which acts as a sensor isolator complicating heat mitigation and they do have room and experience inside the 1 series bodies to engineer some heat away.
Having been a 1 series user for years I am sometimes disappointed in how conservative Canon are with that model, when things like this happen I am very glad they are.
You are right - cold (or heat) not entering the body points to a faulty (or severely underdesigned) thermal interface. This is confirmed by testimonies that when the camera overheats, the body stays cold.Canon themselves recommended using an external fan to cool it down - why? I ask why because it seems fans and even placing it in a fridge does not help much at all since the thermal insulation that prevents heat from entering the camera body will also prevent this type of cooling to become effective. This I conclude from watching a few videos. But I really hope I am wrong.
I am taking a wild guess here, but I think since Canon has a cooling patent (?) design (CR presented it recently), I think the R5/R6 is "already designed" to easily accept the patent's implementation (hardware side). I think that Canon may have prepared themselves for this perceived overheating issue (made by the public and reviewers) before releasing the cameras. Thinking if it (the outcry) does get out of control, it will be easy to update/recall by a rather simple (relative to a redesign) "plug and play" and that would calm people down. Maybe they didn't do it from the start because it would cost them extra money, or parts were not available (Covid). Maybe they released far fewer units than expected this 1st batch to see what actual buyers had to say about it? Then again, why take a chance with their reputation if they new this could be a PR problem from the start?
I'm just speculating.
I still think half of the issue would have been mitigated if they advertised the camera's video specs based on only the modes that are not heat limited… "Does 4k30 without a crop!". Then they could say "Can also record small clips of 8k, 4k60, and 4kHQ, temperature permitting", in smaller letters.
I am more disappointed that the R6 does not have a 4k30 mode that is not heat limited. I managed to upsell myself on the R5 just because of that — I'm only thinking of the reliable non-heat-limited modes as what the camera can do, so for me the R6 cannot do 4k.
Hmm, my best guess is that it is a bump protection for when you fold in the screen with the display pointed towards the back of the camera. Are those parts rubbery?I received my R5 yesterday. Does anyone know what the semi circular piece on left side of the back is for?

But I feel you Loibisch, to me they need to find a way to extend the overheating time a bit more, and more importantly they need to solve the heat build up that occurs by just having the camera in standby or stills mode.
The inadvertent heat build up in the non-video modes and even standby, effectively means the guidelines for recording times are incorrect, and are best case scenarios and not real world scenarios. This can lead some to say the camera does not function as intended. If they can't understand that, they aren't being objective.
I don't know why people aren't understanding this, especially those that portray themselves as professionals. The platform just seems too unpredictable to use as a professional who shoots stills along with any sort of video.
If your camera overheats on a paid shoot and causes delays, you can kiss a future job goodbye. And for some of us who get jobs through ad agencies, that can mean multiple jobs vanishing. Granted you should have two cameras at all times on any professional level, but still... You know what I mean.
Also most are focusing on the R5, but too me the R6 is in an even tougher position, with thermal limitations in every 4k mode. Compromises made to the overall resolution of the sensor, and compromises on all 4k modes, thats a tough pill to swallow. And it's nestled in an increasingly competitive price range.
One or two think I am bashing, or think these youtubers are bashing, but these things are not made up out of thin air, it's a fact that the issues exist. Its not perceived.
Some of you need to start a site called Canon Lovers where you only speak about good things, rainbows and flowers and stuffs.
I think the Camera is Performing as Canon stated but they should have clarified that the record times are from a cold unit. I took my R5 out last night and shot 249 images full Raw, and was able to switch to 8K IPB and had 15mins showing, which I think was the SD cards limit cfexpress card should be here today.
This is what I don't get: every other manufacturer overspecs HDMI out in the Cameras to bypass overheating with external recorders.Esternal recorder however helps a lot, basically 4K60 unlimited going to a Ninja V. But you won't be able to use 4k120, 4k HQ or 8k for even a minute once you've built up the internal heat this way.
Without going into too much detail, the issue is that heat builds up and never goes away. So I could be out taking pictures for an hour or so, causing the camera to accumulate heat. That heat never seems to go away due to the insulation of internal components.
So what that means if I ever want to use the 4K120fps or 8K modes at all, I have to do so at the start of my day. But being an event shooter I can't control when I need slow motion recordings, and I can't just leave the R5 off and in the bag the whole day just to be able to use one of it's basic functions.
