I can now record 8K video on my Canon EOS R5 with no recovery period or lockout until the battery dies.
I filmed the proof and it’s a clear indication that any overheating controversy is the result of an artificially restrictive timer in firmware, rather than any real thermal buildup inside the camera at the end of 20 minutes of 8K recording, monitored by a temperature sensor.
We have been sold a lie.
“Math Class” on Baidu now has detailed infrared thermometer readings of the camera’s mainboard with the back off, showing they correspond closely to the temperature reported in the EXIF data and don’t rise above 64C. He also found that if you remove the internal battery it resets the so-called overheating limitations. So who is telling the truth now, Canon?
One of my favourite guys on YouTube is Theoria Apophasis.
Theo here is the antidote to the gurning frowny face / amazed face shill.
I think his source is utterly convincing about the odd U-turn in the middle of the night involving 65 units of the EOS R5.

In this test, we will probe my Canon EOS R5’s actual internal temperature in Celsius, as reported by the firmware.
Is overheating real or fake?
A Chinese user/engineer disassembled the Canon EOS R5 with the aim of studying overheating.
The hardware is laid out in such a way to trap heat around the CPU.
When does a heat dissipating structure become a heat absorption structure in direct sunlight?
There are now a few confirmed reports by the first Sony A7S III reviewers that the camera has an overheating problem in bright midday sun.

The Canon EOS R5 must be recalled now as this is so far from acceptable. It appears that only 1-2 hours into a stills shoot you can toss aside the Canon overheating test data in the real-world.
In an update to the test at DPReview, Richard Butler found this out the hard way as he describes below.
The real story is not the continuous recording cut off at 30 minutes from cold in normal room temperatures, but that the limit is closer to 2 (or even zero) minutes during a day’s real-world shooting.
