Canon EOS R7 Mark II to Have Stacked 40MP Sensor?

Indeed it's not fully accurate, but it still gives you a good indication if a camera has higher or lower read noise than another one. You can check with other tools such as dpreview's image comparison, the X-T5 is less noisy than the R7 at similar ISO.
The dpreview comparison doesn't give read noise, just overall noise, if that means anything. The photonstophotos shows the XT5 and R7 are very similar for DR, which is an indirect measure of overall noise.

I would like to a have high performing 7DII if and only if it would fit in with my current gear as a 3rd camera with my R5 and R5II. I don't need/want any new lenses specifically for it. I am well aware of all the compromises with the crop sensors. I do think it could be very useful more as an accessory for certain situations than a workhorse if it had the same basic layout of controls and used the batteries, cards, grips, brackets, etc. that the R5 and R6 cameras use. I suspect many potential buyers for a high end APS-C camera share my sentiments.

I would agree with that. But the real issue is how many such buyers there are, and more importantly real ones, not just potential.

Canon launched the 7DII over a decade ago, after which they updated the 70D to the 80D then the 90D, then released the R7 that spec-wise seems more of a successor to the 90D than to the 7DII. That suggests Canon does not see sufficient market demand for a high-end APS-C camera.

Canon may be helping that become a self-fulfilling prophecy by adding relatively inexpensive lenses that deliver good IQ (100-400, 200-800, 600/11, 800/11) and allow FF bodies to achieve far ‘more reach’ than in their DSLR ecosystem.

OK, they were pictures before sunrise at sparks lake with a particular lens. Does that extrapolate to all situations?
No, that's where I was in person helping compare, me and my two uncles were working on comparing them, the onenowns both bodies, and my other uncle and I are working on helping him compare them, our end evaluation was the R3 did better overall for landscape and wildlife and macro, that doesn't cover every situation and is just our OPINION.

Less chromatic aberration, more detail on distant trees, similar dynamic range. Will share files once I can get them from my laptop at home.
The R3 is indeed a such a remarkable camera that its 24 Mpx sensor can outresolve a 45 Mpx one and it can correct in RAW files the chromatic aberration of a lens.

Given what Sigma has given us, do we really need RF-S lenses from Canon?
Yes, I believe so.
I love and respect Sigma in many ways, but...
- Sigma only has 12 APS-C lens all together, and that includes some older ones. 9 available for RF (of which only a single one is ART)
- The f/1.4 primes and the 17-40/1.8 are certainly great products, but that's it. Longest available is the 56mm (no, we are not counting the 16-300). The 50-100 is unavailable for RF. There's no tele, no macro, no tilt-shift, nothing.
- Canon has 0 APS-C L optics. Sigma has 1 ART for RF.
- Sigma AF and IS performance is often behind Canon's
- Canon's new technologies, like Z and VCM are completely unavailable for APS-C.

So even considering Sigma lenses, the APS-C format is veeeeery handicapped.

What we need is to pair this magical R3 with @Michael Clark’s magical EF 70-200/2.8 II. The former will have enough resolution to match the latter. The combo would be unstoppable, especially if someone comes forward with an EF-RF mount adapter filled with magical contrast-enhancing air.

In the first half of 2026, we are going to see new APS-C cameras announced. One of them will be the EOS R7 Mark II. It's possible that we will see them before the end of February for the CP+ show in Japan. I expect a bigger splash from Canon this year than the PowerShot […]

See full article...
If the R7II does come with a new 40MP sensor, do you think the current 32MP will become the standard sensor across the rest of the APSC lineup?
