I bought a Canon EOS R5 and it overheated in the Wifi menu! ALSO: a look at potential solutions

At the weekend I bought the enigma that is the EOS R5 for myself. Foto-Meyer in Berlin were able to find me a rare unit. What all EOS R5 owners have in common is that they have paid a lot of money for a professional video tool. We pay the money, we get to decide what happens next, and I’ll be reaching out to Canon and making this clear. We need to ask them to work on a solution for overheating. It’s worse than you can possibly imagine.

Just need to get something straight – my purchase is NOT an endorsement of the EOS R5. I bought it purely to cover the camera on EOSHD and to help work on fixes for the many issues this camera has. It is in no way a dependable tool for 8K, RAW, slow-mo, high quality 4K or 4K 60p in the state that it’s in. At the very maximum it is a pixel binned 4K 30p camera similar to the Sony A7R IV with the benefits of Canon’s colour science, 10bit codec, top LCD and better ergonomics. Actually that doesn’t sound so bad – but this is not how it was sold to us. It is supposed to be a 4 grand all singing, all dancing, cutting edge 8K/4K video tool and that’s how it should perform in the real world.
