This is my Canon EOS R5 recording 8K video 50 minutes straight until empty battery – video evidence

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.

Removing internal battery resets EOS R5 overheat timer – Are Canon’s pants now completely down?

“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?

Silence of the recall! Is Canon turning around shipments of EOS R5?

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.

UPDATED: Chinese user modifies Canon EOS R5 to improve heat management, but finds artificial firmware time limit

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.

The real-world 4K HQ overheating limit is 2 minutes on the Canon EOS R5 say DPReview

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.

Canon UK on EOS R5: “shoots comfortably on high-end production sets – ideal partner to C300 Mark III” – Why overheating is unintentional

Canon C300 III / EOS R5

Back in April, Canon announced the video specs of the EOS R5 with much hubris.

The camera was indeed intended to shoot reliably in 8K and 4K alongside Cinema EOS cameras…

According to Canon themselves.
