EOSHD testing finds Canon EOS R5 overheating to be fake In: Cameras Posted August 12, 2020 5 hours ago, Andrew Reid said: Hello Wondo Hard to say isn't it? I cannot figure out the business side of it at all. Surely the EOS R5 at 4400 euros is an important release that makes more profit overall than a more niche C200. So either it is internal politics that have played out badly, or possibly a buggy cripple algorithm. But really I do not have the answer. Canon owes us that. It could even be internal sabotage for all I know. The strangest things for me are the following facts: - Canon marketed it as 'comfortable on C300 III productions' and made a big thing about the 8K RAW, so were marketing even aware of the limitation? - The cool down times are unreasonable. After a shut down at 62C, I can leave my camera on a desk for 1 hour turned off and come back to find only 5 mins 8K. There is no chance in hell any silicon or metal stays above 60C for that period of time inside a device that has no power. I even removed the battery, took the lens off and opened the card door to vent the internals. No 'weather sealing' at play here. - There is only a small possibility that the EXIF temp is a long way off the CPU core temps. Also the Chinese guys with the heat guns were able to read the real surface temp of the chip and back of camera, which correlate closely to the EXIF temp we read from the intervalometer shots - Why go to so much effort to build this absolute cutting edge machine.... Only not to let us use it? It's a mega camera. That they saw fit to do this is so far beyond any realm of understanding. People talk about plastic melting or safety regulations... But none of it can explain why 46C after 30 mins causes the camera to shut down immediately when switched to video mode, but 46C after 2 mins allows you to record 15 mins of 8K. 46C or even 62C are so far below what is considered unsafe. The camera is not even hot to the touch. Pulling the Cfexpress card out after the max 8K recording time is up, and that is hot but not uncomfortably... all normal. It gets hotter in my ProGrade card reader. hey andrew, what puzzles me most is how naive and irrational this whole thing is. as you said, marketing it as perfect companion to a c300II without knowing about the bugs? those guys are not 3 year olds or us president.... so there must be a plan or an idea behind this... just not sure what it is!
