90MP Canon EOS ‘R5s’ may be in the hands of testers

The devil is in the details. I have the 15-35mm and 24-70. The 24-105mmf4 too. So that is a start but of course i would buy more and probably primes too over time. However, the devil is the the details and we may be a year or two away from delivery. I may have more money then and how much will it cost then? How many fps and with which lenses? How about the eye AF? Many question and no answers.
Right now I would happy if they just delivered my R5.

If pixel shift is used to get a 90MP image from a 45MP sensor, then shifting it half pixel either horizontal or vertical is the only clean way to do that, and that is not a great type of shift, as you still have lots of gaps in the red and blue channels.
You could shift 1/2 pixel diagonal, but to record that as 90MP would require a very strange raster, and either of these two option would require conversion to a 180MP image, anyway, as to not throw anything away.

Not all improvements in resolution require finer details at the older contrast. There's a zone of sampling where you get optimal results for a variety of purposes by getting pixel-level softness when it is due to pixel density. Such a capture can get bombarded with more noise reduction, and can be resampled to a variety of pixel counts with minimal resampling artifacts, and that includes not only resizing, but CA correction, distortion corrections, rotation, etc.
The fact is, when you have a low-res capture that is very sharp, much of that sharpness is artifact, and the data may look better at 100% pixel view with no resampling, but it is a more fragile capture that crumbles quickly if you do much to edit it with any kind of resampling. Low-res is best used "as is".

That depends on the lens. A lot of EF lenses are pretty soft wide open, and far from their sweet spot, but this is not true for all EF lenses.
Anyone with a Pentax Q and an adapter can see how much center-frame resolution varies with various EF lenses. I get moderately sharp pixel-level details with my 400/4DO II wide open at f/4, sharper at the pixel level than my 24/1.4L is at f/2.8 on a low-density 10D, and the Q is about the pixel density of a 370MP FF. If I put that 24/1.4L on the Q, even in the center of the frame, at f/1.4 is looks like gradients at 100%, with nothing resembling sharpness at that scale.
Anyone who still sees finer detail with a 2x TC on their EF lens than they get at 1.4x, is getting results like they'd get at 4x the pixel density, except that getting it through pixel density, instead, would eliminate the TC's own aberrations and flare (and AF penalty!).
Of course, one must realize that DOF seems much narrower at high magnifications, when you have sharp fast lenses. The conventional concept of DOF relies on perception, usually including low magnification, which makes some depths look more close to optimal focus than they really are (IOW, within a "circle of confusion").

I still have at least one neuron set on cancelling the order, but it is unlikely that anything with higher pixel density and R5-level animal AF will come out soon, and the more I struggle with AF with my 90D in OVF AF mode when animal heads and eyes are clearly in the view as the AF hunts back and forth past them, the more I think, "I could have had that with animal AF".
I will miss the 90D IQ; it has fairly low noise and has the finest, most random noise I've ever seen in a camera that I've owned, and the R5 and R6 both have larger, chunkier chromatic high-ISO noise grain in focal-length-limited situations, but the AF misses on the 90D are so frustrating, and I think that Canon has purposely blocked full use of the AF hardware on the 90D for product differentiation, which wouldn't bother me at all if they actually offered a better-AF product with the 90D sensor (or a FF extension of the pixel size and noise), but they haven't, so far.

.....better dynamic range and better/smoother highlight roll off, all other characteristics being more or less equal (AF, FPS, Noise, etc.).

Very unlikely since Canon has moved on to dual gain. They can’t really use a worse sensor for a high pixel camera, that will be extremely expensive, than for R5.
so 90MP seems reasonable.

This camera isn't for you, and that's OK. That doesn't mean it shouldn't exist at all. I have no need for 90MP either, though I still miss the sweep panorama mode from my old Sony MILCs. But clearly someone does, otherwise Canon wouldn't bother.

you can't do pixel shift high res with an AA filter on the sensor. The R5 has an AA filter.

I don't understand why there are so many voices saying this rumor has no merit. This is the one rumor that Stevie Wonder could have seen coming. Canon has boasted about a 100 and 250 MP prototype cameras for the better part of 5 years now. Of which, the 100 MP sensor has been in a consumer sized DSLR body through out much of the prototyping. Its was always coming, the question was simply when.
Bumping up the "normal" resolution to 45 MP leads quite well to bumping up the high res camera to 90 MP. In the past, I believe Canon commonly got close to that 2:1 ratio:
As far as the final argument over lenses, I'd bet Canon has made any recent lens capable of keeping up with the prototypes they've had for years. Meaning, they likely been building to a standard somewhere in the range of the 100-200MP mark. Also note, an old "low resolution" lens looked quite a bit better on a 5Ds than it did on a 5DIII, and I see no reason for that to be any different for this body as well.

- 1D Mark II N - 8MP compared to the 1Ds Mark II's 16MP.
- 1D Mark III - 10MP compared to the 1Ds Mark III's 21MP
- 5D Mark III's - 22MP compared to the 5Ds - 50MP

Interestingly, this Canon article mentioned bringing an 8K device to market at the same time mentioned bringing a 120mp DSLR to market. I think that makes this rumor even more believable.
For those worried about the lenses being able to resolve that... they also mentioned an large number of the EF line was capable of that in 2015, so there's little doubt that they will have a problem with that for newer RF mount lenses.

Evolution is part of life and part of camera technology as well. 90MP is the future. I think it will be too expensive and I don't need that. Nobody needs that claims will never stop evolution and old photographers will go extinct.
