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.

Results of the first 1-2 hours with the camera out the box: https://www.eoshd.com/news/i-bought-a-canon-eos-r5-and-it-overheated-in-the-wifi-menu-also-a-look-at-potential-solutions/ I see. Something to test then. I wonder if Atomos will be honest about it as well and say that it's pixel binned, not "high quality"!

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.

All the signs point to it being unintentionally crippled this time. It's astounding how broken the R5 is. I now have mine and had it overheat in the Wifi menu. It was just sitting there on the desk waiting for a connection. And the cool down periods are incredibly long. There are signs Canon knew about the problem late on and tried to patch it up with a few features. The overheat control option reduces the live-view quality so the image processor doesn't have to deal with the 8K torrent of data coming off the sensor. The live-view feed seems to be active all the time even when camera is in the menus which is why mine overheated in the WiFi menu with not a single second of video recorded. Well ok... 6 seconds to be exact! Without "overheat protection" turned on in menus, it basically cooks itself doing nothing.

Are you a moderator? No.

I don't think the Jinni thing is exactly RED's proudest achievement is it @Emanuel? In the new video, their lawyer even admits JinniTech suffered as a wronged party and offered him some vague 'lets do business' line - It was pointless for RED to fight this battle. What comes to light is disturbing. Now it is JinniTech suing RED rather than the other way round, what happens if he wins?

Really doesn't look any better than the old 8bit A7S II to my eye. What am I missing?!

Can somebody summarise the latest info?

What's the source for this? I asked B&H and they replied they had no date from Canon at all.

These are unit sales right? Unit sales do not tell you about profit or margin. You can sell a smaller quantity of more expensive high margin cameras. There is a lot of money left in the camera industry. If a couple of soulless corporations leave, then I won't shed many tears to be quite honest. They have put shareholder profits over cameras at every opportunity. And if the quality of images from the Huawei P40 Pro does suggest the camera industry is heading back to making tools for a niche of artists and professionals. I'm fine with that to be honest. Sigma, Fuji, Panasonic... the thinking man's cameras.

Media alert! All EOS R5 owners will get a free R5 shaped box delivered on Monday. Canon look forward to all the creative ways users will find to wrap the camera body and send it back to Japan.

A comment on Hugh's YouTube video explains why the testing needs to be more thorough. Most of the reviews were put out in a hurry and don't tell the whole story on the A7S III thermal limitations. Hugh: I am an Electrical Engineer of 30+ years designing electronics for the automotive world which must maintain operation (NO shutdown) to 85C (185F) and without permanent damage over 100C (212F). The trunk of any car in Phoenix, Houston, or Florida (where I live) will easily exceed 140F for 6 months of the year. I contacted Dan and expressed my concerns with some test errors he made, his interpretations regarding heating/damaging of electronics in general, plus other variables reviewers continue to miss. It looks like you are trying to make some honest assessments here but there are a multitude of variables here that you (and others) are still missing. I don’t think Dan took my suggestions well so I will try you. As you noted, and I pointed out to Dan, internal heat generation (radiation) is outbound as well as thermal absorption (inbound). There are actually THREE thermal tests that must be made to determine if the camera is a net “source” or a “sink”; (1) standard room temp of 23C (73F), (2) outdoor/hi-temp under “sun-load”, but also CRITICAL is (3) which is simply outdoor/hi-temp in the shade! This shade reference is CRITICAL since this test will tell you if the thermal failure is absorption (inbound) vs. radiation (outbound) induced. You MUST do this third test or you cannot make ANY conclusions on thermal propagation of the camera. No reviewer is understanding this point since they are not Engineers. I get that but then they extrapolate conclusions which are simply wrong – some favoring Sony and Canon and some against both brands. Until you have a FLIR type camera showing thermal mapping of the body (AND the body/lens SYSTEM), you really don’t have any idea where the heat source/problem area is located. It is simply assumed to be worst on the back side since this is what Photographers look at all the time. It may be on the bottom or on the sides – no one knows until you look for it at least with some JK type thermocouples.

Only two reviewers have really tested the A7S III for reliability problems in direct sunlight. This isn't surprising given Sony's canny knack of avoiding in-depth reviewers like myself, by giving the demo units to Paris Hilton types instead. But still the truth leaks out... The thermal energy from the sun on a hot day is absorbed by the black chassis meaning the heat sink in the camera acts as a conductor two ways, both from the CPU to the body and from the body to the CPU, the latter really hammers recording times and reliability outdoors. Canon said it themselves in the recent Komodo style cine cam patent... Now that very fast processors are in the latest cameras, heat is becoming more difficult to manage. Well, try again Sony and let's see how long their moral high-ground lasts over Canon!

Seems fishy to me.

You will still buy it though, no? 🙂

Finally the type of test that everyone should be talking about, but nobody bothered doing! Richard Butler: "In just under two hours I shot 164 images, all in CRAW, some as parts of short bursts. I then switched to video mode to capture some 4K HQ footage and was confronted by 04:00 minute limit, despite plenty of card capacity. The overheat warning displayed immediately and, after shooting three sub-10-second clips the camera said it would only shoot for another 02:00 minutes." FUCKING SHIT!

Yes it's true I am changing to SLOG.com and everything will have a magenta tint.

Oops! I wonder if any leaks will come from this. I've always wondered what is behind the total mystery that is Canon.

Stop the bullshit people. I don't logon to read these petty arguments every day.

I think "Leica50mm" is the anonymous online troll account of Canon's US marketing boss

Ahem. "The camera was turned on for 10 minutes to light, frame, expose, format, etc. Then switched off for 10 minutes." Bit of a strange way to shoot. Light, frame, expose, compose... then do what for 10 mins? Turn camera off and have a cuppa? "The camera was turned on again and I shot for 2 minutes, with a 2-minute break thereafter. Camera is turned off for all breaks. Repeat for three takes." So 3 takes of 2 minutes = 6 mins... With leisurely 2 min break in-between each clip! Very light usage. "The third break is 5 minutes, not 2 minutes." So we're now 3 short takes in after the 10 minute break followed by 2 breaks of 2 minutes and another one of 5 mins. That is more downtime than a French air traffic controller. "Camera completed Master and MS1. At the end of MS1, the estimated time dropped to 5 minutes. The 5 minute break didn’t help. During the second take in MS2, the camera overheat warning started to flash." Master and MS1... Apparently these are his made up dialogue scenes. How long were these? "I was able to finish the second take and shut the camera for two minutes. When I switched on again, the estimated time was 1:00, which is less than the roll time. So I had to stop the test." Shoot over. "Overall, the camera was able to shoot for exactly one hour before being on the verge of overheating." 1 hour of on-off short takes and it's dead! NOBODY can work like this... Not even the French.

Neither can the R5 6K is perfectly fine for green screen. Going to 8K brings only marginal benefits and is more taxing in post.

The sound of squealing breaks and a u-turn faster than you can say "no more 4K crop"!
