Dynamic range and other results are up for the R5 over at Photons to Photos. Nice bump in sensor performance compared to Canon's previous sensors, on par with the a7Riv.

I noticed that you can choose to have the R5's IBIS enabled at all times when shooting, or only during the exposure itself. The manual doesn't say anything about how these two modes may differ from one another in performance or battery life. I know that with some lenses the number of stops the IS can provide actually increases if you set the lens to only do stabilization during the exposure. I'm curious to see how this works with the IBIS on the R5. I think I'm going to leave it set to "only during the exposure" and see how it goes. I'll report back on this, but it may take me a while to get a good feel for how the two modes differ from each other in performance and battery life. It's interesting that Canon allows us to choose though.

I suppose having IBIS on all the time would help with framing when you're using a super telephoto, but I don't know how much it really matters to have it enabled at all times when using more normal focal lengths.

my optics knowledge is almost zero but it seems to me that there would be a market for a wide fast lens that focuses only at infinity and Is corrected for coma. It would need a small focus adjustment to correct for temperature. The limited focus movement should make the lens cheaper to manufacture.

i think a 3rd party company that made it for various mounts could sell enough to make a profit. Someone should get right on this and have it ready for the next new moon.

The R5 video review from DPR is up:


For the stills side, I did not get much news out of this. At 3:00 IBIS gets some praise as the best one found in any FF cameras. At 3:30 we also get some positive impressions about IBIS on EF lenses, especially coupled with IS EF lenses. That's good to hear.

Nothing too interesting on the EVF. I didn't hear anything about lag or perceived blur, but the tone was very positive.

Picture quality is on par with competitors in terms of DR and noise. Colors are still great.

At 8:50 the AA filter actually seemed to get a compliment as having only very little effect on sharpness while effectively combating moire. An in the sentence after, the electronic shutter read out (rolling shutter) get's called the best we've seen from any high res FF sensor. I guess that wording includes everything but the A 9 bodies?

At 15:23 the camera gets a recommendation for mainly stills people and it is said that stills shooting was never impacted by heating issues.

The second halve of the video is about video. The point their making is that the 8K, 4K HQ and 4K 120 mode of the camera are really great in terms of quality and are the main attractions for video folks. Unfortunately, these are exactly the mode that will build up internal temperature and therefore require making changes to your work flow and restrict how long it can be used. So the frustration comes from wanting to use these features, but having to compromise on shooting style in order to do so. Which is an understandable frustration I think.

Overall: Not the kind of insights I would want from a review. I think more valuable Info can be found reading the threads around here from people who were lucky enough to get one already.

Well i didn't notice that there is another thread about this, how do i delete a thread?

Bill Claff at Photons to photos published the first measurements regarding the R5 sensor. It looks like it has a second gain stage starting at iso 400, like the sensors made by Sony.
Looks like there is some noise reduction going on in raw, but it doesn't seem to affect image quality if you compare the R5 with the Z7 or A7RIII on Dpreview compare tool.

Just wanted to post that the ProGrade 128 Gold CFexpress card cannot handle 8K RAW and 4K 120

Canon USA has made an official statement and it has been published on PetaPixel about rumored shipping delays for the Canon EOS R5, they do not touch on concerns about the performance of the EOS R5.
From Canon USA:
Orders of the EOS R5 are scheduled to be delivered as initially stated at launch. The first set of cameras shipped from our warehouses this week. We eagerly await the content that will be produced by talented creatives using this camera to be shared with the world.
That’s it, that’s all.
I think it’s best if I just let each individual translate this official statement from Canon USA for themselves.

R5 it's actually a hair better than A7r4 AT ISO 100, R5 11,69 and A7R4 11,62.

There have been a lot of visceral posts from a couple of web sites that have either taken things out of context or clearly just want to appear relevant.
Yesterday I wrote about a lot of reports of long delays in the second allocation of the Canon EOS R5.
I also wrote:
New firmware is definitely coming, but will there be a hardware solution/recall too? It’s starting to feel that way. But let’s wait and see what Canon has to say about the issue and get further confirmation about the second allocation being delayed until November.
I regret using the word “recall”, but I did write it in a responsible way, as in we should wait for confirmation from Canon Inc. themselves.
Let’s be honest, this launch is quite unusual, and a...

Got my r5 yesterday and played around with it a little bit. With the rf24-105 the stabilization is nearly tripod steady. I also tried with a few EF lenses (mainly the Tamron 35 1.4) and the IBIS didnt seem to be on. I can see the micro jitters in the view finder and video. The option to control stabilization is not in the menu when EF glass is attached. Am I missing something here?

Just got my R5 last night and did some quick field testing today.

There wasn't much info about the AF speed for EF lens. So I have taken out my EF 100-400mm f/4.5-5.6l is ii usm and the 2x extender iii to try some bird in flight. The combo yield 800mm f/11 in aperture. However, it work very well for the bird eye tracking in continuous AF. And thanks to the IBIS, i can shoot at 1/500s and yield very stable result.

That's really a big improvement from previous EOS R. And that's not even possible with my 1DX.
Besides, the image detail is awesome with the latest sensor. The image quality with 2x extender and wide open aperture usually not impressive in previous models. I can tell you now it's greatly improved.

I am just another happy owner now

TL;DR: Will there be an RF to Sony E mount adaptor?

I've always shot stills with Canon cameras (From my FTb to current 7D) and for the last 25 years video with Sony Cameras. I have ordered an R5 body. I have a Sony FS5, and use my EF-S 17-55, EF-S10-22, and 100mm EF f2.8L glass on that with a Metabones adaptor.
I am wondering which lenses to get for the R5... it's an opportunity to upgrade my glass to L series. But if I get the RF lenses, would I ever be able to use them with my Sony E mount video camera? Or should I get EF lenses for the R5, suffer the inconvenience of using the adaptor, but enjoy the versatility?
Or do I hope for an Cinema EOS camera with RF mount and switch completely from Sony to Canon?!
Help! I am stuck in my decision making!

Optical limits published review of RF 85mm ff1.2 lens giving it highly recommended.

Apparently, if you have an image stabilized lens on the R5, and you're in any mode besides A-inside-the-square (hereafter [A]), you cannot go into the menu and turn IBIS on or off. It does appear if you have a non-image-stabilized lens, even in the other modes.

So is it on or off? I am *guessing* it's on if the lens IS is on, and it's off if it's not. If that's the case, there's no way to disable it while keeping the lens IS, or vice versa. (So basically, the IS menu item under Shoot7 (or shoot 4 in [A] mode) is simply a menu driven switch to turn all possible IS on for the lens, which for non IS lenses would be IBIS only.) The fact that the menu item isn't "IBIS" but just "Image stabilization" leads me to believe that's basically it. You get all or nothing on image stabilization, and this menu item is there to let you turn it on or off for lenses that don't have a switch on them.

The other alternative, which would be far clunkier, would be to have it track the lens IS as above--but only if you've turned it on in either [A] mode or with an unstabilized lens. Yuck. But that would at least allow you to have lens IS without IBIS if you want that for some reason (power consumption, heating). But there'd still be no way to turn IBIS on and the lens IS off.

Seems pretty laudatory. I haven't read it in detail; I stumbled across it looking for something different.

I noticed something I had never seen before, a 3rd party adaptor with control ring functionality. It is firmware upgradable, so that might help if new cameras or lenses break it. Apparently, its pretty new, no reviews on Amazon yet. Its not cheap at $99, but I am curious. I missed the Canon refurbs coming into stock for a short time yesterday, I was in town. I've been checking for it and have a email notification, but I got home too late.

Hey y'all,

Since my EOS R5 just arrived, I figured we could get this thread started. Will post some experiences/images here.


Here's a few quick images with my EOS R5, using the RF-EF control ring adapter, the EF 100-400mm F/4.5-5.6L IS II, 1.4x teleconverter, and the 1.6x crop mode to get effectively 900mm F/8 at 17 megapixels. Shot in the 20 FPS silent shutter mode, with animal eye detection tracking autofocus. This seriously feels like cheating--the camera perfectly tracks the birds around the frame even when they're in flight, I'm blown away. Still 5000 pixels left to crop with in the 1.6x crop mode, too, which gives even more flexibility.

I'm not finding too much offensive rolling shutter distortion with the electronic shutter here. Definitely a little less dynamic range when raising the shadows, but there's really no blackout or lag in the viewfinder and I'd totally feel comfortable shooting electronic shutter in this kind of photography. It's a lot easier to track subjects in the viewfinder at 20 FPS than it is with the mechanical shutter, in my experience so far.

Trying to bring everybody the content that I would want to see if I didn't have my hands on an R5 yet. I did some comparisons of the R5 vs the EOS R for how well they can recover shadows in dark photos at various ISOs. All photos taken with an RF 50mm 1.2. (From here on I'm just going to refer to the EOS R as R.)

All photos were resized to the same dimensions to negate the different sensor megapixels. No noise reduction used anywhere.

First, an underexposed photo at low ISO. I'm only going to include an original from the R5 here because the R didn't look too different.

R5, 1/60sec, f4, ISO 200


And brightened up version, R vs R5

R5, 1/60sec, f4, ISO 200, brightened 2.75 and raised shadows


R, 1/60sec, f4, ISO 200, brightened 2.75 and raised shadows


R5 detail, 1/60sec, f4, ISO 200, brightened 2.75 and raised shadows


R detail, 1/60sec, f4, ISO 200, brightened 2.75 and raised shadows


Next, same photo at 10000 ISO. But I did not intentionally underexpose it, so I'm not going to post the original. I just pushed the shadows up on both the R5 and the R.

R5, 1/800sec, f4, ISO 10000, pushed shadows by 100


R, 1/800sec, f4, ISO 10000, pushed shadows by 100


R5 detail, 1/800sec, f4, ISO 10000, pushed shadows by 100


R detail, 1/800sec, f4, ISO 10000, pushed shadows by 100

This scared the heck out of me when I first got it. However, all camera functions seem to work 100% as intended. I assumed the IBIS mechanism would be "locked" down, but thinking about all of Canon's IS lenses those mechanisms seem to be rather loose/rattly, too.

A fox appeared out my window as I was unboxing the first R5. A good omen, perhaps.

General impression:
This is a once-in-10-years milestone camera when all these improvements coming together. Extremely happy with it. Sure I'll find some bugaboos, but so far so good. There are some 1D series features in here (voice notes), but at least one left out (AF spot metering).

Quick first impressions:
1) Rolling shutter is amazingly well controlled. Need more proper testing, but first impression makes it seem like my A9 II. Really unexpectedly good. Whipping the camera back and forth at 840mm on vertical grass at 80 yards while shooting at 1,000th of a second showed the same rolling shutter using mechanical as electronic shutter, which is to say that it was limited by shutter speed, rather than readout.
2) Ergonomic improvements from R/RP much more than I'd expected. There are lots of little thoughtful things.
3) Goofing around counting FPS I took 3203 shots so far, and my old lp-e6n battery I used is now 37 percent charged still. The lp-e6nh that they sent with the camera was low on arrival, so it's still charging. My sense is that this is draining faster than a dslr, but not crazily so. Typically when doing 10 fps+, you get much higher number of exposures per battery, but this is still pretty good.
4) Perhaps because I'm using the old style battery, I can get 12 fps on mechanical shutter, but only about 15 fps on electronic. I think when I put the proper battery in, it'll go up to 20 on electronic shutter.
5) [Note: this is revised due to original test having been done on faulty card] After redoing the frames per second tests on two different R5's, here's the rough gist when using RAW format (JPEG goes forever):
a) Mechanical shutter does 12 fps for 13-16 seconds before starting to stutter with the buffer unloading. Low was 150 frames before the buffer kicked in, high was 191 using a faster card.
b) E-shutter does 20 fps for a little less than 3 seconds before buffer kicks in, and then it stutters at an average frame rate of just over 10 fps.
6) Touchscreen focus point selection is lightning fast. The R and RP were sludgy, I felt, relative to the M series, although the M series was subject to lag too - a slightly different phenomenon. Neither afflict the R5. It's super zippy and a joy to use. So much so that I now realize I haven't even tried the joystick yet .
7) Image quality with the resolution is way better than I expected. I thought it would be more akin to the 5d4 /R sensor. The additional resolution is great, but there is more improvement than just that resolution would suggest. I feel the noise levels are reduced per same ISO, but of course we'll need real testing. Just an informed feeling at this point. Wouldn't be surprised if there is a stop improvement, as has been suggested by early reviewers.
8) Tracking is noticeably improved, even from the R tracking after the most recent firmware update. It is on par with my A9 II and A7r4; and the animal eye tracking is probably quite a bit better.
9) Not a video guy, so I haven't even ventured over there.
10) Tried out the IBIS (forgot to test it earlier). I am getting consistently sharp shots with my 600mm f/4 with 1.4x EF TC for an effective 840mm focal length at 1/15th second when viewing 1:1 pixels on a monopod. At 1/8th of a second I'm getting 1/4th shots in perfect focus at 1:1 pixel viewing. This is way better than I got with earlier cameras, and especially good given the 1.5x megapickles versus the R. I'm guessing this is a real-world 6 stops of IS with the lens+IBIS combination. I feel my limitation is now only subject movement.
11) Non-animal, non-person tracking is improved. This, I felt, was a weakness in the R, even after the recent firmware update, relative to the Sony version. I feel it is better a picking an inanimate object and keeping hold of it in tracking, where previously the Canon version of tracking would be a bit slippy on non-living targets.
12) After having taken about 1500 shots within 5 minutes, the camera wasn't even slightly warm. Removed the memory card and felt, and it was slightly warm, but couldn't feel any other component retaining much heat. This tells me that intense stills taking isn't going to do anything to cause a heat problem. Shooting at 82 degrees in sun.
13) I cannot see much viewfinder lag, but I haven't had opportunity to fully test on birds in flight, etc. When using panning to try to introduce viewfinder lag, I'm unsuccessful.
14) Startup time is super fast. Can flick camera on and start shooting in <1 second. Quite a bit less it seems. Faster than I'd be able to raise camera to eye.
15) Just got the 600mm f/11. Surprisingly nice image quality. Oddly won't let me take an exposure longer than .5 seconds as I'm trying to test out the IS+IBIS. Probably doing something hinky that I'll figure out later. IS seems to be 5-6 stops. 800mm still on way.
16) Putting the 1.4 RF teleconverter on the 600 was very surprising. F/16 images were very sharp at 840mm. Tomorrow will make direct comparisons with the EF 600 f/4 + EF 1.4x TC III. The f/4 will be better, of course, but not as much as you'd think. These f/11 lenses aren't as nuts as people thought.
17) I can confirm that the RF 1.4x teleconverter does NOT work with the EF/RF converters, so you must use the EF teleconverters with EF lenses.
18) High ISO (50k) is usable without much cropping. I do think this is about a stop better. Must do real tests, but gut tests look pretty impressive.
19) For kicks, tried the RF 85 f1.2 to verify that a camera can have 8 stops of IS. Wow, it can. The weird thing is that the 85 doesn't have lens IS, so it's not even combining the two (although the RF protocol does provide accelerometer data back from lens to body that is used in IBIS calcs).
20) As per usual, certain things that you select in settings will have effects on your frame rate. These sometimes aren't intuitive. I found I had 9fps in mechanical shutter for some reason until I reset my communications settings, which I'd been futzing with. That gave me back 12 fps. Someone should build a chart of this stuff once we figure it all out.

Does your status still say backordered? Customer service is telling me they didn't receive any which sounds ludicrous....

I got on my local dealer's pre-order list before the R5 was even announced because I had been under the impression that Canon had historically prioritized local brick and mortar retailers. Yesterday I found that they only got only five cameras in their first batch (I was #10 on the list), which I found pretty surprising given that this is a big dealer that serves Washington, DC-based news outlets (Ace Photo in Ashburn, VA).
Is this a sign of changes in the way Canon is doing business with brick and mortar camera shops?

Was extremely lucky to get an R5 delivered today. Want to share some first thoughts, all pretty positive.

-It's noticeably bigger to hold than the EOS R. It will take a little getting used to.
-I was able to get acceptably sharp shots using the IBIS at half a second shutter speed using the RF 50mm f1.2. Sometimes the sharpness wasn't there, sometimes it was dead on. It seems a little inconsistent at half a second. So, if you push it to the limits of what it can do, that's a little less than 5 stops of stabilization.
-The whole camera feels much better than the EOS R. The buttons, the finish of the body, everything feels good, save for a weird clunk noise when you shake the camera when it's powered down. Probably has to do with the IBIS.
-When panning the camera and taking a fast burst using the electronic shutter, the video feed to the EVF is very smooth. I can't imagine this camera will get in the way of tracking fast moving subjects very much. Using the mechanical shutter for a fast burst showed only slightly more of a stuttering motion in the EVF. Still worlds better than the EOS R could do.
-I really like the way moving the AF point feels with the joystick. It feels very "joysticky" for lack of a better term. It's not just a binary push up/down or push left/right feel. If you push the joystick diagonal, the AF point moves diagonal. I will probably go back to using the joystick instead of the touch/drag AF that I was never a huge fan of on the EOS R.
-The shutter noise is much quieter than the EOS R. Just overall sounds nicer too.

Anybody else gotten an R5 yet and noticed a very noticeable clunk or rattle when the camera is moved or shaken when the camera is off? It's much less noticeable when the camera is on. I assume it's related to the IBIS. But wow, that doesn't inspire a lot of confidence. Sounds like something is just loose inside the camera. Does not seem to be any different if I turn off the IBIS and then turn off the camera.

Otherwise very happy with the camera after just playing around with it for a few minutes. But that rattle will take some getting used to.
