When someone has real world data on the battery life on an R5 let me know. I am more concerned about battery life than overheating.
Has anyone heard of an issue with overheating while shooting stills? That would be a real issue for me.

SAN DIEGO – July 28, 2020 –Today, Sony Electronics Inc. announced the long-awaited addition to its acclaimed Alpha 7S full-frame mirrorless camera series⁠ — the Alpha 7S III (model ILCE-7SM3).
Featuring a brand new 12.1MP (approx., effective) back-illuminated full-frame image sensor with ultra-high sensitivity and 15+ stop wide dynamic rangeii, a host of impressive video recording capabilities including 4K 120pi and 10-bit 4:2:2 color depth, a new heat-dissipating mechanism, dual-slot relay recording enabling over one-hour of 4K 60p movie shooting, a new autofocus system, and touch screen interface and side flip LCD screen, the new Alpha 7S III will become the ultimate creative tool for video professionals and all types of hybrid still/video shooters.

So the Canon R5 runs longer in mid day heat than the Sony , who would of thought that .

Sorry for the ignorance, but the thought just occurred to me and I would like to understand how it works. The image that is seen in the viewfinder is coming from the image sensor, so the mechanical shutter would need to be open most of the time, would it not? So what happens when a single photo is taken? When the shutter button is depressed for a single photo, does the shutter close, open (this is where the image is captured - I'm guessing that this image is also transferred to the viewfinder to minimize viewfinder blackout? ), close and then open (so the image is restored in the viewfinder) again for a single photo? What is going on when you take a burst of photos (12 fps in the case of the R5)? I'm guessing that when the shutter button is depressed, the shutter closes to begin the burst and then works like a normal camera during the burst - transmitting each image taken to the viewfinder - until the shutter button is released at which time the shutter returns to full open?

This is what seems would be happening, but I just wanted to make sure that I understand what is happening. It seems like for single images the camera goes through two full shutter actuations?

Canon Inc. has released its financial results for the 2nd quarter of 2020. The COVID-19 pandemic has obviously had a large impact on camera and lens sales, especially with the delays in launching the EOS R5 and EOS R6.
The bolded area at the end of the statement below shows Canon will be entering or developing new spaces for imaging.
From Canon Presentation Material in regards to imaging:
As for the second quarter, due to restrictions placed on people’s movement, there was fewer image capturing opportunities, such as travel and other events. As a result, the willingness of consumers to purchase cameras dropped significantly, leading to a large decline in our sales as well.
As for camera demand, despite the resumption of economic activity, initially in China, and now in the United States and Europe where we saw demand bottom out in April and start to improve from May, we believe it will take time for sales to recover as cameras...

Do I really need the fastest CFe card? I probably wont do 8k RAW but an occasional 40 120fps could be nice.

Are there other advantages like energy saving when going for the fastest available card?

With things looking a little brighter for sports at our small college this fall (limited season and limited venues) I decided to go ahead and pull the trigger on the 1Dx III so I could get familiar with it.

It arrived late last week. No real chance yet to shoot action, but today I did shoot some of our student peer mentors who are on campus early.

Ordinarily, I would be using the R with the 25-105 and the 5DIV with the 70-200, but decided to substitute the 1Dx III for the 5D, just to get a few more hours of practice with the body.

My first impression is very positive. One of the things I fell in love with with the R was the touch screen selection of autofocus points using my thumb. It's a feature that I never thought about until I tried it and quickly realized how superior it is to a joystick for selecting autofocus points and composing when shooting. With the 1Dx III I instantly found that the new smart controller offers about 95% of the same benefits with a DSLR.

It used to be very frustrating when I would shoot with both the R and the 5D and have to switch between the touch screen control on one and the joystick on the other. But with the 1Dx III paired with the R, it just was very intuitive and almost seamless to switch back and forth between the bodies.

For the past year, my 1Dx II has pretty much been used exclusively for sports with the R and the 5DIV used for everything else. I feel that now the 5DIV is going to see limited use. It's still better than the R for birds and wildlife and I still like having the extra megapixels over the the 1Dx also for birds and wildlife. But I can see myself using the 1Dx III and the R for most of my work photography.

The biggest downside I see is the strain it's going to put on my neck, shoulders and camera bag having to lug around the 1Dx III plus a gripped R (the poor battery life of the R has made a grip indispensable for me).

Offering the smart controller on any future DSLRs seems like a no-brainer to me and I expect that whatever body Canon offers to merge the 5D and 6D series, it's likely to have the new smart controller.

I was wondering if anyone else has issues with incidental touching of the LCD on the EOS R. I have large hands, and my thumb seems to alwaysd migrate to tough the corner of the rear LCD. That moves the AF point. I like the touch screen and don't turn off touch, but live with having to double check before each capture. I've had a fair number of oof shots due to this. I can also swivel the display out to solve the issue.

I have studied the rear of the R5 and R6 and it looks like they do have more room. My 5D MK IV also had plenty of room.

You can see my issue in the attached photo.

Ive been looking at the R5 and was curious if anyone had experience with the 24-240. I shoot run and gun style and dont really like switching lenses, but the 24-105 F4 is almost maxed out on the reach for shooting from in the boat.

Of course im using the 24-105 on a Zcam with Metabones, so im not even sure ill be able to use the 24-240 on this body, but if i switch to the R5 it could be an option.

What are your thoughts on going to a R5 or R6 from a 5DMkIV. I photograph Aircraft at Airshows mostly. I have a 5DMkIV and 7DMk2 with Sigma 150-600mm Sport lens. I do not do Video at all so don't worry about 8K video side of the camera. I have lots of EF-S lenses and a few Full frame lenses. My goal is to get extremely sharp pictures of airplanes flying at 300mph going in every direction from far away. Can you use EF-S or full frame lenses with adapters ? Is the R5 45Mp sensor that much better than the 20Mps sensor of the R6 for Still photo's and does it justify the extra cost ? I hear the battery life is only 250 shots which seems very low since I shoot a around a thousand shots per day at a big airshow and use two batteries per day on most occasions. The Cost of the new RF lenses concerns me. I dont want to spend $2500 for an 85mm lens. I need a wide angle up thru 600 mm for ground shots up to far away planes and I cant spend $20,000 on lenses no matter how good. What are your thoughts ?

Some answers for you about the Canon R5:
1. Quality is the same internal vs external up to 4K60, whether HQ or not.
2. External doesn't overheat up to 4K60 (non-HQ) for at least 3 hours.
3. External does overheat at 4KHQ oversampled 24 & 30p after 75 mins.
4. There's no 4KHQ 60p.

Not sure how to directly embed twitter posts. But "Gerald Undone" has a lot of good insight.

If Canon were to bundle a recorder in a "Video Creator" package, and not stuff-up the pricing, they can turn this train around.

Looking for a review showcasing the differences of shooting the RF 28-70 f2 on a R5 vs R (bonus if R6, but really after the R5).

The closest one I could find was this, but it didn't really compare shooting with the glass on one body vs the other (it was more a simple lens review)... figured someone might get a benefit from it so sharing it...

I held off on getting this lens or the RF 24-70 f2.8 due to indecision (choice being F vs IS)... however all that changes with IBIS. Also curious as to what the increased megapixel has to offer w/ this lens.

Feel free to move this over to the lens subforum if it's better off there...

Canon News posted about a patent recently about actively cooling an RF mount camera with an adapter. In this patent, it’s a cooling EF to RF adapter.
In  Japan Patent Application 2019-186871 You can see the adapter and the flow of air from the adapter.
Canon News says:
The camera does have to be properly built to handle heat transfer from the sensor to the lens mount, but this is certainly something Canon could accomplish.  One of the engineering problems that even Sony and others have is how to cool a sensor that is not fixed in place because of IBIS.  Flexible heat transfer materials made of polymer do exist, so it’s possible to cool the sensor directly even with IBIS...

… are really getting on my nerves. I'm not asking for folks to have full reviews, but really basic stuff is being omitted. Ragging bit on the Northrups here but they are by no means the only ones:

- "I couldn't recover this highlight." OK, was that RAW, HEIF or JPG? If it was RAW... how did you process it? I haven't seen any reviewer with access to raw conversion tools yet. Does the R5 have highlight priority? Was it on?
- "I had trouble tracking a bird once I started shooting" That's really important to know. But can she regularly do that with an OVF? How does it compare to other mirrorless Z7/A9/XT4? What drive mode? Fro was doing some great indoor sports shooting with the 1DX3 in live view—why would the R6 be different?
- "Battery only lasted an hour" while driving a 500mm lens with a 2x extender, presumably with IS on. How many shots? How does that compare to a 5D4? A7 series? I've found even a 100-400 will chew up batteries on my 5D4 with heavy IS, and it starts to slow down with drained batteries.

Not asking for super controlled/detailed reviews at this point, but adding in those pieces of context would take like 20 seconds of script time. Really don't want this to be a dig at Tony/Chelsea who are doing solid work actually getting the camera into the field—just wish they'd provide some basic contextual information.

Unless you’ve been living under a rock, you’ve probably heard about the heat issues with the Canon EOS R5 when recording high-resolution 4K or 8K video.
I haven’t touched the camera, so I’m not jumping in with an opinion. However, what I have noticed on social media is very different results and conclusions about using the EOS R5 as a video camera regarding heat. There have been those that have said it is unusable for videography work, and there are others that have said they haven’t had an issue and have loved shooting with it.
Knowing social media, it’s probably somewhere in the middle.
Now we have the company Tilta that is showing off a fan that quickly mounts to the rear Canon EOS R5 when the screen is flipped out. As you can see by the images below, it’s pretty and may look like it it’ll be an effective solution, but I...

Just noticed this in Bryan's R5 review so far at The-Digital-Picture: he added in a electronic vs mechanical shutter comparison: https://www.the-digital-picture.com/Reviews/Canon-EOS-R5.aspx

Scroll down to the ceiling fan photo.

There is slight visible distortion there, but considering the speed most ceiling fans are spinning, this looks pretty exciting. I was already willing to deal with some very extreme and painful rolling shutter on the EOS R in silent mode when I was shooting very slow, quiet action settings where the shutter noise would cause more problems, so maybe this means that the silent shutter will have even more use in general assignment work. Still will probably go with mechanical shutter on extreme action, but will do my own tests when the R5 arrives.

Hi

I found this https://faq.canon.jp/app/answers/detail/a_id/101699#1
It explains how the R5 can only do 12fps in some situations.
Its not in english but google translate can translate it in chrome.

One of the tables looks like it is saying that it can only do 12fps mechanical if the battery is 60% or more.
I also read some limits in the specs talking about mode a, b, c. This could be the same as green, white and white blinking for the continuous shooting icon. So the next step down looks like it is 9.2 fps. That is not too bad. But then I would really expect to get that until the battery is near empty?

Does anyone know any more about this? I was really wanting this camera to maybe replace my 7D II and 5Ds.
So continuous shooting is something I require to work. Also a bit worried about battery life. Hope to get 1000 or more shots from two batteries.

Folks;

Based on what I have read here on CR, the new R6 uses essentially the same sensor as the 1DX3. Yet the 1DX3 ISO (per the Canon website) is 102,400, expandable to 819,200. The R6 is 102,400, expandable to 'only' 204,800.

Any thoughts on why the 2 stop difference?

(my experience with the 5D3 suggests that the last two stops are not terribly useful - I find 25,600 useable, but 51,200 and 102,400 on the 5D3 too noisy...which might suggest that I would find 51,200 on the R6 useable, but perhaps 204,800 would be useable on the 1DX3, hence the question)

Thank you!
