Episode 87: Canon EOS R5 Overheating is Completely Fake!

In this episode I talk about the fact that the new Canon EOS R5 overheating is totally fake and is in reality a firmware baked in timer.

Episode 87: Is the Overheating on the EOS R5 Fake?

You’re listening to the Liam Photography Podcast, I am your hose Liam Douglas and this is episode 87. I want to thank all of listeners for Subscribing, Rating and Reviewing in Apple Podcasts, Google Podcasts and anywhere else you might get your podcasts and also remind you to check out the Liam Photography Podcast Facebook Group.

So in this week’s episode I wanted to talk about the possibility of the EOS R5 overheating issues being completely fake using an artificial timer in the firmware. This story begins last week, when a user on Chinese social media site Baidu broke open their EOS R5 and found that removing an internal button battery “reset” the overheating timer, allowing them to go right back to shooting without any recovery time. A PetaPixel reader shared the info from that Chinese site but it had not been confirmed immediately.

Over the last week members on DPReview Forums posted the information as well and then it was also picked up by some Youtubers including Matt Granger an Tony Northrup who all confirmed using various “hacks” that the overheating did NOT actually have anything to do with the heat inside the camera. Some users discovered if you yank the battery while the camera is still shooting video it prevents the camera from writing the bogus overheating data to the NVRAM and thus you can put the battery back in after 10 seconds and keep right on shooting with no waiting or “cool down” time required.

I don’t recommend doing this as the risk of corrupting your video is too high and it can cause damage to the camera and your memory card as well. So it looks as though the “overheating” issue is completely based on a recording timer that is baked into the firmware and has nothing to do with any kind of temperature sensor or actual heat inside the camera.

Now why would Canon implement a lame timer that cripples the camera after a certain number of minutes of 8K or 4KHQ video shooting. Is this because Canon knows something about the camera that the general public doesn’t know? Did they fail to implement an actual heat sensor to keep down the cost of the camera and they are using the timer in the firmware to hopefully prevent the camera from actually overheating.

If the overheating is completely fake does this mean that Canon will correct the issue in a future firmware update? Only time will tell on that one but hopefully Canon will come up with some way to resolve the issue. Now I doubt Canon will actually “fix” the issue as they don’t want to take away from their cinema line. Think about it, Canon releases a hybrid camera that can shoot high quality stills as well as 8K and 4KHQ video and then set the price tag at $3,900 instead of the $8,000 that a camera of this level would have demanded.

Canon knew that consumers would not want to fork out $8,000 for a hybrid camera when the 1Dx Mark 3 is only $6,000 and although it cannot shoot 8K video it is a more durable camera than the EOS R5. Tony Northrup has the same opinion and talks about this same subject in one of his most recent videos which I am including in this episode’s show notes as well as the 1 cent hack that Matt Granger talks about in his recent video on the EOS R5’s overheating being totally fake.

So, now, where will this leave Canon users who bought the EOS R5 for it’s high end video? Only time will tell on that question, but Canon has proven that their cameras are better at displacing heat than Sony’s as Sony had to add air vents to their most recent 4K capable mirrorless full frame cameras to displace the heat internally. On the EOS R5 the Chinese user who tore his R5 apart shows that the entire time the camera is recording video the internal temperature never gets above around 47 degree celsius. This leads myself and others to believe that Canon was being honest when they said they were able to keep the internal temperature down by re-arranging the layout of the internal components to allow more separation and keep things at a more reasonable and constant temperature.

One more thing I wanted to touch on in this episode is the large amount of false information that is circulating on various camera groups especially on Facebook where users are claiming that the EOS R5 even overheats when shooting stills. This is totally bogus as reported by the thephoblographer.com website. I have been reading articles on the site for quite a while now and the site is dedicated to only stills photography and no video. Given that the owner of this site has had the EOS R5 since it first came out and has been shooting stills with it for months with no overheating issues at all during stills use.

Moving forward, hopefully Canon will come up with some sort of middle road where they will allow users more time to shoot video or at least remove the bogus 2+ hour cool down time and allow users to shoot again after say 15 to 30 minutes instead. I can certainly understand Canon not wanting to hurt their own cinema line of cameras which cost a hell of a lot more money, but they need to come up with some way to make their EOS R5 owners happier about their purchase.

Alright, that is it for the continuing discussion of the EOS R5 “overheating” issue and some ways people have found to “hack” around the limitation. It’s entirely possible that one of the users from the Magic Lantern site will come up with their own customer firmware that removes the recording time limits and allows users to have the FULL capabilities of their new camera.

Before I sign off for this week, I wanted to remind listeners that the new summer contest has started and this time the show is giving away a K&F Concept TC2534 66 inch carbon fiber tripod/monopod combination. The contest link has been posted to the Facebook group and will also be in the show notes for this episode and was added to last week’s episode as well. The contest is running from August 25th, 2020 to October 25, 2020 at midnight going into the 26th and then the random winner will be chosen and notified so that their prize can be shipped to them.

Summer Contest

I decided to go with this tripod as it’s the new model I chose to replace my Gitzo tripod with as I needed a tripod that had a taller extended profile than my Gitzo had. I did not having any luck getting a company to sponsor this contest so the prize is coming directly out of my pocket, but someone will be getting a new carbon fiber tripod this fall so make sure you enter for your chance to win!
