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

[Maximilian]

Again, changing one setting as simple as the "fast" or "quality" preview in DPP's settings can significantly change the result you see on your screen when you open the same Canon raw file in DPP.

So you have no solution for my comparison experiment. I got it!
But thank you for beating around the bush for so long. Could have saved you and me some time.
@AlanF showed some RL examples. Thank you for that, Alan.

No, there are good and better copies of a lens. But the theoretical best copy of the EF 70-200/2.8L II is not going to be quite as good as the theoretical best copy of the RF 70-200/2.8L. And the theoretical best copy of the RF 70-200/2.8L Z is going to be better than both of them.

No one has theoretical copies of any lens. Theoretical lenses are, as someone else here likes to call some things, unicorns.

Uncle Roger has also pointed out that the best copies of an expensive lens do not necessarily beat the best copies of a cheaper lens.

The graph below shows plots from multiple copies of two prime lenses. Let's call them 'Red' and 'Green'. The Green lens is a fairly expensive, pro-grade optic. The Red lens is a cheaper, consumer-level prime. You'll see that there's one copy of each in roughly the middle of this graph, away from the main cluster at upper-right. I'd return both of these samples to the manufacturer. So would you – they're awful.

None of the examples Alan showed you are "SOOC raw files", though.

You can say “upper left quadrant” lenses if that helps you understand the point. I understand that you believe you have an excellent copy of a particular lens. To claim that your lens is better than other lenses, based on comparison with pictures posted online taken with those lenses, remains an unsupportable claim.

I beg to differ! I have several theoretical copies HarryFilm lenses!

But they can be compared, can't they? Yes or no? And if "no" why in detail?

Sapphire-coated acrylic, I recall.

It’s as you imply a reasonable comparison with Canon DPP4 used for processing for both with same minimal settings.
