I live in Canada where it's -30c for 6 months of the year! I will be shooting that 8K Raw without any issues! Btw, Canon just announced Raw may be available for ALL resolutions!

Somebody needs to make a battery grip that is also an active cooling system for these cameras.

There is a guy who uploaded his 8K R5 footage here on KZfaq and this is what he said about his experience From the author "The original oversampled 4K movie is crazily sharp. But after uploaded to KZfaq, the difference between oversampled and non-oversampled is smaller. So I may suggest non-oversampled 4K is enough for online video. If I took 8K video around 20-25 min straight, it will overheat but it still allows you to take 4K 30p at will. I have encountered the overheat issue at these conditions. Though it will overheat, I found the 8K video is totally usable and it is already remarkable for a small camera like this. Positive on this. 1) At Outdoor 32C, took 10 x 1-min long 8K (or 8K oversampled 4K) videos within 30min; took 30 min to go the next location (camera is ON/OFF for photo-taking during the period); Took another 10 x 1-min long 8K (or 8K oversampled 4K), then it will overheat and you cannot record 8K by then. However normal 4K 30p is still available and I have taken another 1 hour normal 4K footage without any heat problem (but 4K 60p is not allowed though) 2) At Indoor 23C, it can recorded a total 27 min 8K RAW video using a 512 CFexpress card. Then it will overheat and no more 8K. Then I have turned off the camera for 10 min, it will then allow another 10 min 8K after cooled down a bit (note: the camera can tell you how much time you can take 8K before overheating)"

Thanks Max! The R5 will be a great camera for people making ski & snowboard edits out in the cold, lol 😄

I’m buying a small freezer for my studio just for this

Main ways I’ll use the R5 - 4k24 All-I/IPB - 4k120 IPB - 4k60 IPB Key features I wanted: - Full-frame - IBIS - Fast Autofocus in slow-motion - No crops

Im waiting for your video test on EOS R5 Max

Its is important to remember that these are stills cameras offering some video features that are beyond many similarly priced cine cameras. Considering that, overheating as a compromise is worth it.

One answer. GH5 . Record unlimited in 4k 60

I mainly shoot photos, and when i do shoot video, I don’t have any need for 4k. Ain’t nobody got time for that kind of file size. So the r5 sounds perfect for ME. I haven’t heard anyone talk about eye af, and i hope it’s great, but the ibis has me very excited

If you want to take videos ,get a Camcorder, R5 is a Camera . Doubt if I'll ever use the video options while I have a Sony 4k Camcorder

The 5DIV cost $3499 when it was introduced in 2016. With labor and material cost going up each year, plus R&D cost Canon needs to recoup, the new R5 costs $3899. Only $400 difference and the R5 packs tons of new features in it that the 5DIV does not have. I think this camera is a very good deal.

Of course, they didn't include a fan to keep the body as slim as possible. The current generation of engineers cares more about style then substances. It's no surprise at all.

as long as I have 4K at 60 for slow-motion thats all I need everything else is just added perks. And of course good dynamic range. For me the R6 is a perfect run and gun camera and hybrid camera when i need to switch between photo & video fast! My RED is great but i dint want to build a cinema rig everytime i need to shoot. Sometimes i need to be low profile and quick, i need auto focus i need to just point and shoot while still getting some cinema quality on the go. And thats why this camera is perfect its not ment to compete with a RED or a camcorder and shoot for 30min to 60min non stop. If you wanna film live shows or church events buy a camcorder. If you wanna shoot music videos,weddings,short films this camera can get the job done. Or at least work as a B camera to a A cinema Camera

When the EOS R was released it was immediately trashed (unfairly, IMO). I'm having deja vu all over again. There is no perfect camera. Canon listened and produced two full-featured cameras in record time (not to mention the possibly upcoming R3 & R5S).

So the canon rep said the camera can still shut off by just browsing through menus. That somewhat contradicts them saying it only has heat restrictions in 4k60 and 8k. I am waiting to see if the camera shuts down during normal operations if it gets too hot. This makes it pretty much unusable for any professional outdoor use. I regularly shoot in conditions well above 30 degrees c and not knowing if and when the camera will shut down is a level Stress I wouldn’t want to ad to everything else that’s going on.

Yeah, when you said add an external fan, that was so Sony a few years ago. So experience in dealing with the overheating in Sony cameras should directly apply, 1. use a dummy batter and power externally, 2. use an external recorder, 3. get a cage, and do no keep the display close to the camera. And 4. attach a small computer fan behind the display. And for last resort 5. Cold packs and ice chests.

Some people were angry with your first video clip about overheating, but now canon to some extent respond to your comments positively, so those people should acknowledge your comments.

Props to Canon for giving us so many killer video features on a stills body. Also 24fps is 20% fewer frames than 30, so likely even better performance in regards to heat if you’re in one of the affected modes.

I believe with the EOS R6 you can record without limits at 4K with IPB compression. Also no limits for 1080p at 24, 30, or 120fps.

Canon should make mini fridges.

Overheating for all 4K modes for the R6 is a huge disappointment. Unless this gets addressed it's absolutely a deal breaker.

Canon tech reps were on line July 9 giving the recording times for 8k and 4K 60. It seems I was the only one that saw them.

There is a youtuber named Moc Nguyen" that has up samples of the 4K 120 10bit Clog footage you can download.

Can't wait for your awesome review about the R5 and R6 like you did with the "A7II vs Z6 vs EOS R vs Xt3".

Great vid max. Can't wait to see that footage at 8k

Correction, SD cards get nowhere close to 350MB/s *sustained*. SD burst rates are not equivalent to the V rating, and the fastest cards are V90, which do 90MB/s, good for non raw recordings

One thing baffles me: No 120fps in europe, only 100. It’s a huge artificial feature gap. Why is pal/ntsc still a thing, when it’s really not. Give every area every fps option.

Why would I need to shoot 8k?

and wheres 4k 24? maybe that mode is not limited by heat on either.

So the R6 actually is barely a 4K camera....guess I may have to cancel my preorder

r6 2500$` price tag is too high for low res camera with a limited 4k recording .

The moiré should not be a huge problem thanks to the presence of a low pass filter. But it means also that the image quality will not be as sharp as it wasn't there...

Hey, I made the edit. Nice work Max!

And what about if I’m shooting a football game for example STRICTLY STILLS!! Do I have to worry about overheating in liveview, or just in general?! Because if overheating is a problem for pictures this is a dealbreaker?! Max?!

I'm a sony shooter and I dont get why all of a sudden stills cameras are being solely judged by how good of video camera they are. I partially blame manufacturers for highlighting video over stills on what is most definitely a stills camera first and video camera second.

Hahaha hopefully Canon provide a official cooling fan for R5 and R6.

3:22 "it doesn't overheat" 😂😂😂👍🏼 laugh so hard

You just can't escape the laws of physics here. I don't think people realize just how much processing power and hard drive space 8k will require

I like the fact that there's a "hot surface" decal behind the LCD screen. Hopefully this means external cooling solutions could be an option if the sensor is radiating into the magnesium body. #engineerstuff

Maybe .. Canon should release a Canon R5 C that has an internal fan and is designed for videography?

I just want to know who will do a interview at open sunlight at 30/35°c. I think every professional will use 8k for B roll only

To everyone complaining about not being able to shoot for hours at 8k or 4k120..... where exactly are you expecting to store all this wonderful footage? a 1tb Cfexress card is about $900 and you'll only get 52 mins of 8k raw footage onto that card...

What a bummer to see 4k recording limitations due to overheating even in the R6. At 60p I could live with, but even at 30p as well is pretty disappointing. 👎 And to hear the Canon rep say that they didn’t want to sacrifice body size for cooling... I don’t know about everyone else, but I would definitely be okay with a larger body if it meant some form of cooling.

I just bought a small cooling gadget ( 2 fans with battery 5CM * 7CM) from a seller who selling cooling gadget for SONY. He did some modification to fit the EOS R5 size. It can stick at the back of the camera. Let's see if it can help.

well nothing like Lumix gh!!!!!!!!!!!!!!!!!!! I have work with then en the tropic during summer and noooooo problem with them.

I have a feeling Canon is planning on putting out a R5 C a little bit later that will have a fan and be less weather sealed. I think that was probably always the plan but that they wanted to get the main 5d/6d replacement hybrids out there so they had good cameras that were capable for stills (and video) to match the lenses they have (unlike the R). This way they could finally start transitioning their pros over to mirrorless as we've kind of seen evidence of with the videos they've put out focusing on various pro photographers and genres.

I wonder if it’s possible to create a heat sync casing - like an underwater casing or phone case, but just to suck out heat 😅

I think the camera is just passively cooled. How can you "activate" passive cooling when framing shots or being in the menu? From a physical standpoint the camera will always give off heat if there is a temperature difference between the body and the environment. The only thing that could be a cooling mode is to park the sensor with the 5 axis stabilizer or completely disabled it. I

Hahaha! Max's attitude towards R5 is very different from the previous days, many smiles today😂

Funny how people who weren’t even going to upgrade to it are now dismissing it because a function they weren’t going to use anyway doesn’t perform correctly.

Great video Max. You should keep doing more camera news more often. These are so fun to watch and they probably don't cost a lot to make. No camera purchases, on lens purchase ect. Everything apple pro basically does this with his channel and he's a millionaire just talking about iphone rumors. Remember when I had 50k subs and you had like 25k? Now you are killing me. Anyway, I love what you are doing. Keep up the good work!

As always Max excellent content. You're KZfaq channel always has the best content and I like the professional look and feel to all of your videos. Excellent job! The other thing that is important to me and why I am still a subscriber is that I trust your reviews. I have purchased several cameras based on your recommendations and will continue to do so. I want to thank you and your brother for all of your hard work and look forward to your review of this Canon R5/6.

My thing is why bring out 8k if ur camera can't handle it. Why do i have to do all that just to cool the camera down, make no sense.

I can't wait for you to get your hands on them and do a comparison!

Well at least the camera could be used in the winter. And in canada thats mostly the whole year. So canon made a camera for eskimos.

NEW RUMOR SPECS FOR THE A7S3 FROM SONY ALPHA RUMORS.. 600mbps bitrate 16bit RAW output Sony claims 15 stops dynamic range iso is still the same as previous a7s2 - 409600 Base ISO for slog 3 is 160 instead of 1600 (As7II) on the pre-production unit.

Why RAW only in 8K? Is this a technical limit or another cripple hammer? I think even RAW in 2K would be extremely useful. Color grading and resolution are really two separate issues. You don't always need videos that are in 8K, though that option is really great if available.

Did people just completely forget that cinema cameras are a thing? Get a Blackmagic Pocket Cinema or Z-cam E2 if you want hours of continuous recording.

I'm glad they didn't put a fan in. This is primarily a stills camera. One of my frustrations has been all the absurd comparisons to the a7s III. Obviously this should be compared to the a7r 4 or the a73 (for the R6).

I would have invested more in the HDMI, HDMI 2.0 and even 2.1 does exist so the overheating issues are less problematic

It’s not really surprising that the camera will generate a lot of heat especially with 8k and 4K 120 frames - weather sealing and small body was always going to have some overheating when using those functions. For me it wouldn’t stop me from purchasing, you would just have to factor this into a video shoot if shooting in those modes that produce heat.

Did anyone believe that a camera, with such sealing level, would be able to record 8K without overheating??? Even in 4K, like Canon, other cameras overheat. Max, I Know that you look primarly to the video usability, but this is a stills camera with the 8K bonus for $4000. Adding the IBIS at the same level or higher than the micro 4/3 or probably the best auto-focus on the market, the ergonomics, the menu system, the colors, the superb lenses and the reliability that other manufacturers still don´t have it, really don´t understand this wave of complaints. Like compairing the R5 with the next a7s.. really? Who buys a sony a7s to shoot essentially stills? I don´t know anyone.

The R5 is a video centric camera, and probably should have had a small fan in it. But "forget about it!" lets keep this body compact and small! But again if you are mainly a photo still shooter 45mp is good to have.

Great video. Will HDMI to an external recorder help to reduce the over heat issue? Can you also leave the R5 EVF off in this mode & control externally with less heat issues ?

For us wildlife shooters, that aps-c crop mode is killer because it gives more reach! Yay, Canon! Hurry up and get this thing out. I need it bad.

Not a camera for me. High Price & Heating Issues.

I think it might be possible to design a grip for a dummy battery and an active cooling system. This system would simply extract heat from the battery compartment. Edit: Someone with this idea was faster than me in this comment section ^^

Might be interesting to see a specs list without any features that are limited. This would be helpful for professionals to decide if they should upgrade or not. Using camera for features that only work some of the time isn’t really feasible for anyone working in a professional environment. When you have multiple people standing around essentially getting paid by the hour and possibly a talent you only have for a short amount of time (eg a CEO of a company) the last thing you want is a camera that holds back everything because it needs to cool down.

Nowhere does anyone say whether there is heat issues with 24p

It’s a great camera, but a crippled camera that could have been amazing. Rather than crippling the camera by excluding features in software, it’s crippled by physical design. It’s a damn shame.

Awesome, back to talking about cameras and such, and not about pandemics. :) Good times!

Sorry Max, at the end of the day I would still use the R5 over the orange-ringed rectangle.

So I love what Panasonic has done with their S1 series. I don't mind that they're big, they perform great and they weren't afraid to put a fan in the S1H. If only they would've fixed the AF before releasing the S1 line they could be killing it right now.

Thanks Max. These cameras just have too many scenarios to overheating. I live in a warm area Texas, and these would be a liability for any outdoor shooting most of the year. Happy for those with Canon lenses (FYI, I was pro Canon shooter for 40 years). But these are not for me. If the new Sony as rumored, comes out with excellent video specs and no overheating plus no time limits, then no Sony owner would ever move to these Canons. If you are a Sony user, wait a bit. Sony knew what these Canons would cripple, and that is why Sony moved their A7SIII intro until after the Canon intro. Cheers

From experience with the 5Dmk2, the external fan doesn't really help.

Great! A hand warmer for winter shooting!

Max, does the R5 require a new plug in for FCPX to import RAW or will the existing Canon plug in work?

i wisch 3 Function button to start 4K 60 / and one to start 8K / and one button like shutter itself for 4K120 so i set it once and dont need to go to the menu again to change setting ... can some one d this for me

Wait - what was the bad news?

R6 only last 40 mins at its lowest 4k shoot? WOW!

would the lower bitrate via the new firmware would be less stressful and hence dissipate less heat?.

This will be HOT topic for months to come.

Hello, max I am from Montreal Canada and I hope you will make a full review of the canon r5 for shooting video with the latest firmware. Thanks and Happy new year

I was told by another KZfaqr who is testing the R5, when the camera overheats, you can still shoot normal 4k30, which is good news.

Since 4k 30fps has no overheating, can you ask if that mode will be unlock from the time constraint via firmware ?

Shoot stills and video short clips...done

Hope they add pixel-shift super high resolution for landscape photography!

if you spend 4.000.00 Canon should provide a fan adapter to hold the fan. This is getting bizarre.

R6 with Atomos Ninja V

Be careful when talking abour CFexpress speeds. The number on the box/card are peak numbers. good cards will get you around 800 MB/s sustained write and lesser ones in the 450MB/s range. 8K RAW looks to be 2.1Gbps, which is around 250MB/s, not 325MB/s. Generally you want a good card that you know can sustain speeds well above what you expect to record at so that you don't drop frames. Also, if your footage is important, do not use an SD card. It might save you a few hundred dollars now, but the cost of shooting footage is way higher. You might be able to get away with a UHD-II card, but the NAND in a CFexpress is much more reliable, you get the option of faster speeds, and much faster offload. Don't spend $4k on a body, thousands on lenses, and then skimp on your media. Just don't.

Hey Max, Good update on the R5/R6. Can you share if this is on Atomos Ninja5, does the overheating go away. Also SSDs are cheaper than CF express cards. Just know the HDMI has limitation to record up to 4k60, not sure about the Shogun 7 though. Any thoughts on this? Also, gotta know you have an A7S3 in your hand but holding back! 😉

Can't imagine how many hours of frustration you've dealt with to acquire the knowledge you have on working with constant craziness with updates, different computer systems and cameras etc. lol

Will the same RAW update be coming to the 1dx mark III?

Ahh, that's a bit disappointing that the R6 can't do 4k30 without the potential of a heat related limits. I was thinking it was CPU/encoding, but maybe it's more due to the sensor and IBIS.

This is why 8K, 6K and RAW is not necessary for your average consumer. Not many professionals I know shoot in those file formats apart from the ones who are working on tv shows and that’s usually 4K RAW, but it’s filmed on a proper cinema camera rather than a mirror less camera. I feel like now the roles have been reversed. Before Sony would pump out crazy features and put them in their cameras but they’d have reliability issues such as overheating etc Whilst canon were reluctant to add in features until they could guarantee 100% reliability. Fast forward to the past few years canon have been going crazy with the features whereas Sony have been focusing on reliability, colour science etc I guarantee you the A7siii will be the better camera and will have better reliability. I’ve heard battery life isn’t great on either R5/R6. A7siii will have fans similar to S1H, better battery life, flip screen and a body design similar to A7RIV. Most people don’t even have 4K TVs the standard is 1080, once 4K becomes the standard then we’ll need 6/8K etc but it’s totally overkill. We’re not making Hollywood movies

Pixel binned 4K will be much better in low light compared to oversampled crop 4K

Would the camera overheat if you're just doing high-speed continuous shooting?

the firmware webpage you showed - it says 'under consideration'... so is it coming 100% maybe even by the time the cameras will be released or it's just a maybe till somebody sometimes decides to do it
