The Canon EOS R7 Mark II is in the Wild

A detail I like on the R7 too. And the thumb wheel is easier to acces compared to that of the R6. But the third wheel is missing in comparison to R6.
One unique feature of the R7 is the auto level by IBIS which is a great advantage when shooting with long focal lengths - it helps me to concentrate on breathing and keeping the composition without fiddling with other parameters.
The auto-level is great, I think until the R5ii/R1 the R7 was the only Canon camera with the feature. It could use some improvement for video however; right now if it's active and your pans aren't completely straight it rocks back and forth, hampering handheld use.

Apparently it disables EFC (electronic first curtain) too!


That’s a bummer. As the full shutter has shutter shock, and full ES has so much rolling shutter.

But if you don’t mind, could you clarify what you mean by “rocks back and forth?” Does auto level just stop working in pans? I’m asking because I’m considering trading up to an R7I for stabilized video on primes, and auto-leveling for stills.

Been using the R7 exclusively since early 2023 (and exclusively ES since Early 2025), the shutter shock and rolling shutter are vastly overstated IMO, I pretty much only notice the latter with hummingbirds and clearwings. Auto-level is fine in stills, but in video it can wreck footage. I forgot to turn it off in the linked video and the rocking was quite unsightly, especially around 1:29

Oh hey, I’ve seen your videos before! I love all the HDR uploads.

That’s exactly what I wanted to see though, thanks. Yeah it looks a bit annoying, but not deal breaking, and I suppose I can use Gyroflow+phone gyro data if I need something more stable.

Why won't the R100 work with RF teleconverters or the control ring adapter?

Just the normal amount of cripple 🔨

A $350 camera and a $500 extender? And, for acceptable results, a $800 + lens is needed...

But that lens cannot be the RF 85/1.2 DS…because it also is incompatible with the R100.

Wow, I did not know that. Do you happen to know the reason for it?

No idea, not even enough to speculate. I’ve seen a post blaming ‘the older hardware in the camera body’. Maybe? The R100 uses Digic 8 but so do the R and RP, and those work with the TCs and the 85L DS. However, there are probably different Digic 8 variants.

I also trawled for the reason and only came across the same post. It's indeed a mystery.

Probably something related to autofocus and that "defocus smoothing" coating? As the R100 works with the 85mm 1.2 without the coating.

Look through Canon's supplemental info tables, and the R100 has uniquely limited AF on many lenses: https://cam.start.canon/en/H001/supplement_0110.html

That 85mm DS, specifically, also loses support for other autofocus-adjacent features, like DoF preview, that other lenses have.

Perhaps the DS coating "muddies" autofocus performance enough to break it on the R100. To avoid the (admittedly rare) scenario of someone trying the DS on the R100 and finding it's manual focus only, I'd wager Canon decided to exclude support entirely.

Defocus smoothing should not affect autofocus. What it does affect is exposure metering at apertures wider than f/5.6, wide open the lens is f/1.2 but T/2.2. DS also makes DoF deeper at apertures wider than f/2…I expect that is why DOF preview is problematic.

Checking into it, I noticed that the other two Digic 8 R-series cameras (R and RP) required a firmware update to enable compatibility with the 85L DS, specifically to address proper metering with the lens. Thinking about the implications of that, I expect Canon decided it wasn’t worth the investment in a firmware update for the R100, given the presumably minuscule number of users who would pair that lens with that camera.

Out of curiosity I tried the R100 with the RF 1.4xTC and the RF 100-500mm. There are no error messages and the camera focuses and takes the pictures. However, the camera doesn't seem to register the presence of the TC and the EXIF, as diplayed in Lightroom Classic, doesn't register the presence of the TC either. I also tried DxO PL 9 and it doesn't register the presence of the TC.

Thanks for sharing this. I asked the wrong question. What I hope to learn is the reason for this statement: "There is marginal benefit with pixel sizes of <3 µm and meaningful benefit with pixel sizes of <2 µm." I am guessing that above 3µm, the light gathering ability of FSI and BSI sensors does not have a significant difference, and that this difference becomes 'meaningful' below 2µm. If so, what are the main reason(s) for this dependence on pixel size?

There’s a finite minimum amount of space taken up by the photodiode circuitry, so as the pixel gets smaller that circuitry takes up a greater fraction of the pixel area, meaning more light lost when that circuitry is in front. The 3 and 2 µm sizes aren’t specific cutoffs, the benefit with decreasing pixel size is continuous.

As an example, compare the Sony RX100 vs the RX100 II, where they introduced BSI to the line. The cameras were 10 months apart and otherwise very similar (they added a tilt screen and WiFi, I think). The pixels are the same 2.4 µm size, and BSI gives about a 1/3-stop benefit on noise. That and similar comparisons of larger and smaller pixels are the basis for my statement. I’d call 1/3-stop marginal benefit, anything less isn’t really meaningful, IMO.

A better sensor architecture is all the R7 needs to solve its rolling shutter and read noise problems:

- Dual Conversion Gain to help with high ISO read noise
- More column parallel ADCs to increase readout speed without hurting read noise (or just clock the existing ones higher and increase noise)

That shouldn't raise the costs too much nowadays and you don't even need BSI for that.
Really, it all depends on the direction taken for the R7 MkII and the desired optimization for the sensor.

The dream would be stacked BSI and low-noise circuitry but that would put it on par with FF flagships. One should obviously expect the cripple hammer to strike regardless, Canon are too conservative with product segmentation.

Crazy idea: what if Canon killed the R3 and put the R7 II in that form factor? I'm not saying this is at all probable. Just noting that it kind of makes sense. The R3 will have a tough time upgrading to a Mark II version without infringing on R1's market. On the other hand, many of us think Canon has short-shrifted us resolution/distance limited shooters. Putting a BSI stacked sensor of around 45mp in an R3 form factor on a crop sensor and juicing the processors to do the sort of pre-baking done in the 1 series cameras could be appealing. Maybe add that expansive viewfinder too. People would expect to pay an extra grand for it. -tig

PS: Whenever I come up with a "brilliant" idea for Canon's product planning they do the opposite. So the R72 will probably come out in m-mount .

My guess is that the camera you are describing is a $3000 tp $3500 camera. All the evidence from the way Canon and Nikon have been reluctant to upgrade or even make a high level crop sensor camera makes me think it is unlikely. Nor will Canon care if the R3 mark II infringes on the R1 sales, as long as the R3 mark II sales are adequate. Either way they sell a profitable camera.

I could see the R3 model number being used for a high mp beast. I’d have thought that from a marketing position this should be more attractive than introducing a R5S
That depends on how much Canon wants to charge for it. The 21MP Canon 5d2 made the 21MP 1ds3 virtually unsellable. The 24MP Nikon D3X was replaced after 4 years by the D800, with 50% more pixels, a less rugged body and a 60% price reduction. People who want lots of pixels don't seem willing to pay for extreme ruggedness

Indeed that’s what history tells us so far. I’d see an ultra high mp R3ii as basically a ‘R5S’ configuration.

These day's Canon have really mapped their customer's shooting requiremens. Professional photographers is a very wide category of shooters. Sports and press photographers have very different requirements to say landscape, wildlife or even wedding photographers. Camera bdoies sales also are not indicative of the buying populace, not eveyone who has a R1 sells their frames for a living.
Sports and wildlife photographers both need cameras with speed, ergononics, top AF and buffer speed / size. Other features like top resolution at lower in their priorites than say a landscape or bird photographer would want.
Cameras like the 5Dii and the 1Ds3 were at the cutting edge of camera developement and the 5Dii was a far later camera, both revolutionary at lauch and state of the art. But a 1Ds3 was looking a little long in the tooth against the 5Dii, except for AF, battery life, ergonomics and buffer. These days, the tech is pretty common to any manufacturers and across the various models in a brand. The AF in a R10 is shockingly more capable that that of the 5Dmk4 for example.
These days we have so many options and choices both lens wise and camera. My R6ii / R5 combo are way more capable than any cameras I've owned previously. That said, I am considering flipping my R5 for a R6iii, because of the superior WB/Colour science in the R6 range. I love the camera but the Af is a little pedestrian and I'm finding the R5's files need more work in PP due to the colour choices of the camera.

There is different “colour science” for portraits (skin tone warmth) and for nature (correct biological colour). Maybe the R5 series is optimised for Nature and the R6 more for studio work in general.

Canon knows how much profit they made from 5Ds/5DsR bodies, compared to the 1Ds series. If we see another 'high MP' body (i.e., significantly more than the R5 line) from Canon, I strongly suspect it will be in the R5-series body type and not the R3.

I agree with you. Sadly, since I do not personally like it, but I think you are right more likely than not
