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

1. I hope this is true! I got an R7 to use with the RF-S7.8MM F4 STM Dual but when it comes to video recording, because EOS VR Utility has to crop two eyes out of the 4K footage, the 3D footage ends up being worse than 1080p after processing. If they come out with an 8K60 APS-C camera, then that will be a huge leap in quality for stereoscopic recording.

2. I'm still a bit concerned because the original R7's noise performance was quite bad above 3200, and with the greater pixel density it could be even worse if they don't do something else. Also, is this the highest density pixel sensor that Canon has(or will) released?

3. Well, the current R7 seems to be on a permanent discount: first, at Black Friday and cyber Monday it sold for 999 €. Two days after that Canon announced the Christmas deals (running to the end of December) and the R7 again is available for 999 €. So, Canon is basically selling of all the inventory.
   
   Funnily, the R8 hit the exact same price point (Christmas deal is even better since you get an adapter for only 19 €) and pattern. Is there a mkii on the way as well?

4. There are two cameras I would consider from canon. The R7ii for wildlife (I already have lenses) and what is rumoured is fine for me. The other one would be a rangefinder style (similar to the Fuji X-E5 or the Sony a6700 line), for street and travel. Canon has nothing in that segment, only SLR style bodies or video centric bodies without a viewfinder. Those two APS-C cameras would do it for me.

5. I like the idea of stacked sensor and would improve on rolling shutter effecks(assume with higher readout speed) but this mega pixels going to create a lot of higher noise. Would have been better with 32.5 stacked sensor. Also lot as APSC lenses would suffer from low resolving power and push it back to poor quality.

6. There are so many things hitting my inbox about the R72. It's really hard to vet the info.

7. I think if Canon was going to do this, we're going to see Canon's first BSI and/or stacked APS-C image sensor.

   
   It's still very expensive to produce stacked sensors due to the fact that they have to be stacked. That involves fabbing multiple sensor layers and then (literally) bonding them together in a very precise process. This is why it was never going to happen for the R6 III to get the R3 sensor, and it's why it does not make sense for the R7 to get a fully stacked sensor.
   
   The only BSI sensors Canon has used in R cameras thus far have been stacked ones. Will Canon finally move to non-stacked BSI, and do it first in the R7 II rather than the R6 III? Maybe? It's more likely than a fully stacked sensor, but I personally wouldn't bet on it happening. For whatever reason, Canon seems perfectly happy sticking to FSI sensors.

   If they bump it to 40 MP and decide the speed of a stacked sensor is not needed, then I can see them using BSI. The 1-4-type sensor in the PowerShot V1 (made by Canon, AFAIK) is BSI, and has the same pixel size as the current (but older) R7. Benefits of BSI are most evident with pixels <2 µm, but there does appear to be some modest benefit with the 3.2 µm pixels of the V1 sensor, so there should be more with the ~3 µm pixels in a 40 MP APS-C sensor.

   "The number “40” would be good for the marketing department."
   
   I agree. It's harder to convince a casual observer that a sensor is "new improved" if the megapixels stays the same.

10. I am not directly in the market for an R7m2.
    But if I was and knowing the IQ from a friends R7 I really hope for better pixels (s/n, high ISO performance) than for more pixels.
    If Canon can deliver both at the same time, that'll be welcome, for sure.

11. 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 […]

    The good news is — I guess — is that if we extrapolate the photosite density of the APS-C sensor… Canon might eventually catch up with the 60MP FF sensors that Sony has had for a few years… as Sony is rumored to go beyond that.
    
    Swell.

12. My username may give it away, but I am extremely excited about this piece of news (or rather, rumors). I had hoped for a BSI and stacked sensor, the latter of which was pretty much a given in order to deliver 40FPS at full 14 bits of depth.
    
    But didn't dare dreaming about 40MP, which, in my eyes, Canon would only do if they could actually improve SNR and high ISO performance. Seems like they may have achieved just that! This will be an amazing powerhouse. Can't wait to see it announced, hopefully with some great APS-C lenses to follow by Canon, Sigma and Tamron!

13. I hope it is 40mp just to see another wave of upset 7D DSLR fans. I want to see a post in 2030 of someon explaining why they're still waiting to switch over to mirrorless.

14. 40mp stacked sensor? I need to change my pants!
    
    If this is true, it could be the answer to my dreams for an airshow/planespotting/wildlife camera (with the 100-500mm) without having to spend $10K on an A1 II setup. Of course, it'd have to have a healthy buffer and hopefully a CFe card slot to eat all those pixels in a high FPS burst.
    
    I hope the 100-500mm can resolve that insane pixel density well enough.

    Swell.

    Extrapolating a 40Mpx sensor to FF gives 102Mpx. The current 32.5Mpx extrapolates to 83Mpx which is already higher than the Sony 60Mpx sensor. In fact, the ancient EOS 90D and the M equivalent had 32.5Mpx APS-C years ago.

    40Mpx is only 11% more linear resolution than 32.5Mpx, and each 40Mpx pixel is only 10% narrower so it's not going to make much difference in the DLA, the demands on lens resolution etc. It will make no difference to the S/N and high iso when you look at the whole image, because they are independent of pixel size. And if you pixel peep and look at the engineering S/N, each pixel will have only 10% less S/N, ie, less than 1/6th stop.

17. 40 MP crop translates to 102 MP FF, which is coincidentally the right number for 12k video. I smell an R5s (possibly packaged as an R3 II for power reasons) in the offing.

    I'll trust your math. I got 14.9 😜

19. Cool. :-|
    Will it have vastly improved AF over my hugely disappointing R7? If so, I'll buy it, otherwise I'll pick up a refurbed R6ii, sell my R7 and be done with buying new bodies for now.
