Administrators Andrew Reid Posted August 10, 2020 Administrators Share Posted August 10, 2020 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. A huge thank you to them! 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, oversampled 4K, 4k 60p or 4K 120fps 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 does it?! But this is not how it's sold to us - it is supposed to be a $4k all singing, all dancing, cutting edge 8K/4K video tool and that's how it should perform in the real world.

Video Hummus Posted August 10, 2020 Share Posted August 10, 2020 The HDMI overheating vs menu overheating is very strange. It does point to maybe this being an intentional cripple hammer blow. Which could mean good news if canon is willing to fix it and give the camera more acceptable behavior closer to A7SIII. If they did that do they not understand they would sell an absolute boat load of these cameras and with it a ton of RF glass? Whats their angle for so badly crippling this poor camera? They gave so much room for Sony to steal away mirrorless sales. Maybe they thought with the success of the EOS R they could get away with selling an EOS R to their customers again with headline grabbing specs that are crippled to the point of being unusable. Strange, very strange product here. Quote Link to comment Share on other sites More sharing options...
UncleBobsPhotography Posted August 10, 2020 Share Posted August 10, 2020 Those thermal pads doesn't lead the heat anywhere... 🤔 The only real connection between the hot parts and the body seems to be around the screw holes, that's way too far for the heat to travel before reaching the chassis.

Strange, very strange product here. It is very strange But if you remember Gerald and Richard's live-view / stills shoot tests where 1 hour in the camera was at 0 mins for 8K without having recorded a single minute, it's a similar thing to what I experienced in the Wifi menu. The menu is just an overlay and the live-view feed is still likely active and being processed, ready to display immediately again when you dismiss the menus with a half press of the shutter. I think the 4K HQ option gets deactivated when the Ninja V is connected too, which may explain the extended record times to that, because it is pixel binning or even line skipping to the HDMI monitor.

Nezza Posted August 10, 2020 Share Posted August 10, 2020 Andrew is having to fix the ‘mighty’ Canon flagship camera for them. Ridiculous situation really. Quote Link to comment Share on other sites More sharing options...
cameraeye Posted August 10, 2020 Share Posted August 10, 2020 It is just bizarre. Either way you cut it, why did it get released? I’m looking forward to your findings and possible workarounds. Quote Link to comment Share on other sites More sharing options...
Administrators Andrew Reid Posted August 10, 2020 Author Administrators Share Posted August 10, 2020 Yes, good question. Why did it get released? It is baffling. Management would have known. Engineering would have known. Testers should have known - they tested it! Reviewers soon knew. I found out within an hour that it overheats sitting in the menus with 4K HQ set to on and overheat control set to off. So it is very confusing to me why it is on shop shelves marketed as a professional C300 III B-cam! You can speculate and make up your own theories as to why Canon thought they could get away with it, and whether it is intentionally crippled, or buggy, or just incredibly broken at the fundamental LSI level.

wolf33d Posted August 10, 2020 Share Posted August 10, 2020 Let’s do a petition on change.org for a fix from Canon. Emanuel 1 Quote Link to comment Share on other sites More sharing options...
Administrators Andrew Reid Posted August 10, 2020 Author Administrators Share Posted August 10, 2020 Regarding a campaign requesting Canon to fix it I am all ears. First step should be to reach out and persuade them directly, allow them to realise how seriously their customers view this problem. The petition might be useful to show to Canon in terms of number of people they have upset. If that fails then the second step should probably be a class action lawsuit. Not sure a petition will change much in that situation but a lawsuit would. Emanuel 1 Quote Link to comment Share on other sites More sharing options...
zerocool22 Posted August 10, 2020 Share Posted August 10, 2020 Could you try without a cfexpress card in the slot and only a sd card to see if that makes any diffetence at all? Quote Link to comment Share on other sites More sharing options...
gt3rs Posted August 10, 2020 Share Posted August 10, 2020 slashcam has tested RS and 8k, 4kHQ is 16ms!!!...... boy they have created what would be the perfect hybrid but nobody can use for video because the recovery times are just insane. Either is software crippled or it has a big HW flaw.... if the first let's hope they remove/fix if the second why they don't sell a version in a bigger body with a Fan?!? 8k 30 RAW, 4k oversampled from 8k 10bit with 16ms RS and AF and nobody can take advantage..... what a waste. Problem is that is a very good photo camera (best canon ever) so even if they do nothing they will sell a ton.... Emanuel and Kino 2 Quote Link to comment Share on other sites More sharing options...
Nezza Posted August 10, 2020 Share Posted August 10, 2020 Less than a week since release an R5 open box at Wex... https://www.wexphotovideo.com/canon-eos-r5-digital-camera-body-used-1748094/ Start of a trend I’m sure. The returns should at least get Canons attention. Quote Link to comment Share on other sites More sharing options...

So I will be waiting for Andrew's feedback about it, we could get several workarounds to use this camera in most of the situations. Quote Link to comment Share on other sites More sharing options...

rawshooter Posted August 10, 2020 Share Posted August 10, 2020 Philip Bloom is - by his standards: unusually - outspoken on the R5: "This is the first camera I have used in memory that punishes you for using it. [...] I spent £4200 on a camera I cannot use most of the time and that’s ludicrous! I truly hope they find a way to fix this debacle." zerocool22, Emanuel, Geoff CB and 3 others 6 Quote Link to comment Share on other sites More sharing options...
