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.
Canon really threw the kitchen sink at the EOS R5 specs sheet. What about the kitchen fridge?

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?
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.

DPReview has released their Canon EOS R5 and R6 test of overheating, using the final production models. Technical editor Richard Butler remarks “Lack of dependability makes them a poor choice for much professional video work”.

In a historic interview granted only with the EOSHD YouTube Channel, a Canon colour science engineer finally sat down to talk about the EOS R5 overheating issues.

Let’s have a look at thermal management on small mirrorless cameras. The solutions shown here prevent overheating on the Sigma Fp and Panasonic S1H during long recordings. The Sigma Fp shoots 4K RAW internally from a 6K sensor and the Panasonic S1H shoots 6K internally in 10bit 4:2:2 V-LOG.
Canon can learn from the design of the Sigma Fp and Panasonic S1H when it comes to offering professional video features in a small weather sealed body.

Let me be clear, it is great Canon thinks video users are important again. Well done Canon for such a comprehensive set of features. Now, as you may have seen earlier, Canon quietly sent EOS R5 overheating test results and timings to UK dealer CVP, who were the only ones to actually mention it in a video.
Now there’s more.
