I suspected Canon to cripple this camera somehow, someway but this artificial heat limit and recovery time is really out of line. Such arrogance! But you know what? Canon may think they control the market but we have the power to control them by boycotting Canon. Especially nowadays with the camera industry bleeding as it is. Force Canon to stop this BS. How? If you already purchased the camera, return it. If you have it on order, cancel it. Cancel all orders with Canon. Write letters to Canon showing your disgust. Call Canon and voice your disapproval. Fight Canon with your pocketbook. Stop the BS.

Thanks for sharing that video. This is one of the best reviews about this camera's heat related problems. The wedding simulation he did is spot-on and how weddings nowadays are recorded. I hope Canon sees this video and how they botched this camera's ability to shoot weddings.

Is there any mention of improved recovery time? That's the other factor. Is the crazy recovery times due to temperature or firmware? If it's firmware, there's no hope other than Canon to fix it.

Maybe it was intentional? Cannons do get hot.

Have you heard of the pandemic?

These workarounds don't work for all modes. What about 4k 120p? Can't do that currently with an external recorder and even if you could, you've now lost compactness which makes it difficult or impossible to use in the field for wildlife videography. It defeats the purpose of the camera for how I would use it. Even if you primarily shoot stills, the damn camera heats up and makes it nearly unusable when you do want to take video. I fail to understand why anyone would use these workarounds for a camera with bad engineering design. Why promote this garbage? Why spend thousands of dollars on a camera that works half-assed at best and requires you to spend another thousand to use it for some of it's video modes but not all? If you want to stop Canon from making shit cameras stop buying them.

I assume the same but you know what they say about "ass-u-me"?

Yes, it does. Not sure about photos but Phillip Bloom has stated that it can record video to both cards simultaneously.

Just for fun, I took the side-by-side video clip from both cameras and did a little tweaking to get them a bit closer to each other. (See below) There's some truth to Canon's ability to produce a more pleasing look right out of camera but both cameras can certainly be adjusted to match. I have used Andrew's Pro Color adjustments in the A7III to produce "Canon Color" directly out of the camera by tweaking settings in-camera. That is one feature of Sony cameras that are often overlooked. You can tweak profiles to the nth degree. In current Sony mirrorless cameras however you can only do so much tweaking due to dynamic range limitations and 8-bit codecs. Where the differences typically exist between these consumer cameras and production cinema cameras boils down to dynamic range and how many stops of light you have available in the highlights and shadows. I am quite confident that the new A7SIII can be tweaked in-camera to produce many different "looks" straight out of camera and with better dynamic range and a 10-bit codec.

Both Undone and Bloom are the best IMO. I always look forward to their reviews. I did learn a few new tidbits from Bloom's review of the A7SIII that are important to my style of work (wildlife): Animal eye detect autofocus does not work in video (stills only). Philip has started a petition on this, here's the link if you want to sign this. Tracking autofocus does not work while using Clear Image Zoom. Tracking autofocus does not work while using an external monitor. Punch-in does not work (manual focus) while recording. Clear image zoom works to 1.5x. Lot's of positives with the A7SIII but there are negatives too. I wish this camera had Canon's autofocus capabilities. With that stated, I'd much rather deal with these issues than a camera that can't recover from overheating until hours later, has line skipping in 120p 4k and humongous file sizes.

I can't remember what reviewer mentioned that they were amazed that after the camera cooled down to the point that the body didn't feel hot any more that their record times were still severely hampered. It does make you wonder if Canon's firmware is designed to purposely cripple this camera. I usually don't buy into conspiracy theories but one does have to wonder with Canon's history of intentionally crippling cameras.

Canon's actual response reads That doesn't really say much of anything.

Latest word from PetaPixel for what it's worth...minutes ago... https://petapixel.com/2020/07/31/canon-responds-there-is-no-delay-in-eos-r5-shipments/

Let's not forget the low-light capabilities of this camera. Northern lights in real-time!

While some of you are underwhelmed, I'm elated as long as 4k 120p works as stated. I've been hoping for a camera that can do that along with excellent autofocus. Great for wildlife filming! Yes, 30 min limitation but I can live with that as long as I don't have to shut the camera off afterwards to let it cool down for 2 hours. I'm being cautiously optimistic.

As much as I dislike Tony Northrup, his latest video did some side-by-side comparison's of the 4k resolution of the R5 and R6. The 4k 120p out of the Canon is incredibly soft. You probably wouldn't notice it in videos involving people, but getting feather/hair detail in wildlife is critical and it appears the resolution from their 120p 4k is comparable to up-rezzed HD. Probably line skipping. As far as any 10 bit 422 camera causing edit nightmares, my experience is different than yours. Z cam footage is easy to edit with Resolve. Works like a charm. I suspect Sony not to follow in Canon's footsteps. We shall see. I definitely want to test some footage. Yes, the audio on 4k 120p (A7SIII) is definitely a plus although it is very hard to get clean audio nowadays while filming wildlife. Usually there some man-made noise going on. Very frustrating.

For myself personally shooting wildlife, all I'm looking for is a camera that does 120p 4k reliably with good autofocus and good ergonomics. I've been using a Z Cam E2 and it's been a good fit but it's bulky and no autofocus. The A7SIII with the Sony 200-600mm lens appears to be an excellent fit for me as long as I can shoot all day with it. I could have easily gone back to my roots with Canon since I still own the 600mm f/4 lens, but three strikes and you are out: Unreliable due to overheating in 4k 120p Ridiculously large files/hard to edit Footage reveals it is incredibly soft in 4k 120p Now if Sony can avoid those three, I'll be more than happy with the A7SIII for what I do. It would have been nice to have a 20 MP sensor for stills, but I'll work around that by carrying two bodies with me at all times: A9 and A7SIII.

It could have been shot with the A7SIII or possibly the S1H. He definitely uses the S1H for a lot of his work. But does he have two of them? What was filming the shots of the S1H while he was filming? The Ninja V that he is using has a small scratch on the upper left-hand corner. This appears in the car video as well as the leaked photo. For sure he has a connection to the leaked photo of the A7SIII.

I'm skeptical about the Tilta cooling system. You need to keep the sensor cool somehow. I saw on Canon Rumors that Canon actually has a patent on an actively cooled R adapter. That seems more appropriate as it would be in-line with the front of the camera where the sensor is located. Of course you could only use it on older EF mount lenses but that seems like a smarter move. Cool the front of the camera not the rear.

Can you imagine the R5 with a cooling system like the S1H that wouldn't overheat? Canon could have raised the price by $100 and included an active cooling system into that camera and I'd still have one on order! What were they thinking?

Right. They played it smartly. Why didn't Canon do the same is anyone's guess. I'm wondering how the A7SIII will play? It's is a less mp sensor which should be easier to keep cool but wonder if the in-body stabilization may be nothing more than gyroscope meta data that's used to stabilize in post. Like the FX9.

This very well explains why the GH5S never had in-body IS. The data rate off the sensor is too high to prevent overheating with an in-body IS sensor. It doesn't overheat because the sensor is heat-sinked. All these manufacturers are doing juggling acts to keep their camera sensors from overheating due to high data rates. Black Magic and Z Cam use the same sensor and also no in-body IS.

Has an active cooling system for the in-body IS sensor.

It would appear the crux of the problem with the R5 and R6 has to do with sensors that float and are not heat-sinked. They have to float for in-body IS. (Notice how professional cinema-style cameras do not have IS built into the camera? The FX9 has a gyroscope for post-stabilization. No floating sensor. Makes sense if you want a professional cinema camera that won't overheat. In a nutshell it appears these camera manufacturers trying to produce high quality FF video/stills camera hybrid have to decide on a path to take: Forfeit in-body IS to prevent overheating Have a built-in active cooling system such as a fan and possibly retain in-body IS Provide in-body IS with no active cooling and allow the camera to overheat and consider it a mainly stills camera with some limited video capabilities. The crux of the problem is floating sensors with no way of adequately keeping them cool.

BTW, I am curious as to how well the Tilta cooling system will work. In typical applications, the peltier module needs to be heat-sinked to the actual component using a conductive paste. Having it up against the case of the camera will help, but will it completely prevent it from overheating?
