An interview with Roger Cicala of Lens Rentals on Canon RF 600mm teardown and more

I have been a long-time follower of Roger’s blog at Lens Rentals, which gives us not just a rare glimpse inside camera gear, but also an expert eye on construction quality, weather sealing and the repairability of it all when you drop it! To celebrate Roger’s latest article I had the chance to put some questions his way, to dive into his thoughts on the 600mm, the potential for a ‘universal’ mirrorless mount and of course the EOS R5 overheating controversy.

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.

Canon EOS R5 so-called overheat timer defeated by a single screw in battery door

UPDATED.

On Friday, I received a message from the A1ex, developer at Magic Lantern to point me to an interesting theory suggested by one of their contributors, which he believed could defeat the so-called overheat timer on the Canon EOS R5. Initially I was skeptical as to whether it would work, especially because my first real-world test using the method did not seem to reset the timer.

But then, a break-through.

Magic Lantern just became Magic Screw!

Hey Squarespace – Reconsider your sponsorship of Tony Northrup perhaps?

Something must be done about the ethical standards of this planet and there’s no better place to start than in some small way, on YouTube. For years I’ve had my articles and forum posts co-opted by people like Tony Northrup with 1.42 million subscribers, without any credit or acknowledgement. A lot of hard work goes into writing this blog, the understanding of the technical side of my filmmaking, the journalism and sources, the research and investment in cameras. I do this purely to help people and because I live and breath technology and cinema. To see Tony Northrup fish around for a big story so he can sell his adverts around it, mislead people and not even understand the topic, pump misinformation out and not credit where he got his “breaking news” from is absolutely unacceptable.

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?
