The R7 Mark II with 39MP: It Sounds Spot on – and here’s why it makes sense

[Richard CR]

Okay, so the rumors are sounding as if it appears that the Canon EOS R7 Mark II is indeed set to arrive in the first half of 2026 with a new 39MP APS-C sensor of BSI variety, either stacked or unstacked. As someone who enjoys delicious megapickles, I'll be happy with 39 versus 32.5, even […]

Whatever pixel count the Mark II will get, whatever sensor design, the performance will be very interesting.
Can't wait what readout speed and what DR and s/n it will deliver. I hope your predictions are right @Richard CR.

Yes, I really want this lens for my next APS-C camera, as Canon doesn’t think we deserve a modern fast kit zoom.

And I can tell you, you will love the 18-50 DC DN. At least I do.

IMO the question is if the DPAF performance will suffer from the smaller pixels.

*assuming stacked sensor*

The efficiency gained by going stacked from front side illumination should be enough to offset the small efficiency loss by slightly smaller pixels.

In theory, of course.

It’s all depends on readout speed. If same or slower than mark I, no birders would want it even pixies on the birds are higher

I'm holding out for hope of a stacked sensor. If it's not stacked, it would need to at least have a fast enough readout speed, but I'm not sure it'd be fast enough to satisfy those of us who want, above all else, a fast readout speed. For me it's not just about warping bird wings or propeller/rotor blades, but also the longevity/durability of the camera. The more I can rely on electronic shutter and less on mechanical, the longer the camera (or at least the shutter mechanism) will last, as well as retaining possible resale value if that comes to pass. I'd honestly rather save up for an R5 II instead (not an impossibility regardless) than buy an R7 II that I wear out the mechanical shutter on because I suck and rely on spray-and-pray instead of skill.

Regarding the comments on a R5s or R3 I could see that from a marketing and sales position it would be beneficial to have the ‘high resolution’ model as a separate model - the R3ii. Also would then make the positioning in the line up clear.

If the shutter is well-designed to begin with, it's going to last for hundreds of thousands of actuations and not an issue at all.
Even if it does, it is considerably easier to replace than in a DSLR. Apart from the EOS R failing sometimes (first one with sensor protector), I don't know of other issues with Canon mirrorless regarding shutter wear.

Agreed - sort of.

the mirrorbox assembly was extremely complex but that was usually seperate from the shutter assembly outside of timing.

but I think Canon and others have done alot of work around mirrorless to make it smaller and easier to manage.

and yes, it must be certainly easier to replace as well.

I really don't understand readout times. The R7 can be truly bad for bird and insect wings but I have never had any problems whatsoever with the R5, which is only twice as fast. The R5 does have rolling shutter effects on panning against backgrounds with vertical lines that come out sloping, but not with wings flapping.
