Canon EOS R1 to have a version of a DGO sensor?

ARRI has a patent for that, not sure how generic it is. Canons DGO in video mode seems to be different enough to avoid lawsuits.
Actually, Canon’s DGO mode seems very similar to Arri’s. The key ingredient is that the different gain levels are captured simultaneously. Without this ghosting would appear in all but static shots. Which is why Red’s high dynamic range mode is more of a gimmick.

It could be that Arri licensed this tech to Canon.

If Canon is going to Sony's level, it's evolving backwards. Have fun with eye-lash AF and AI chip marketing gimmick

Well I owned the R3 since launch. Great camera. But compared to my A9III it feels a generation behind. The A9III is the superior camera in just about every measure. It has the fastest, most accurate AF of any camera available today. So I guess they ironed out the bugs.

So many possibilities. But in the end, I’ll bet our wild imaginations will conjure up a way more exciting camera than is actually released. I’m going to expect to be disappointed… and maybe it will turn out that I’m pleasantly surprised.
well, you can surely thank rumor sites for profiting from their mistakes and providing you disappointments, not canon

I refer you to this. We do try our best, we don't randomly spout off everything without careful consideration.

I would assume it would use parallel pipelines. Takes one image from the sensor into two amplifiers which are offset by whatever amount they see best. Basically one sensor exposure/readout that is put through two gain paths which the processor then combines to take the best of both based on peaking/crush.

This will basically take two images with one signal/exposure going through the photosites then combine images.

I have few theories but they dont' pass the sniff test, so i really dont' know. no matter what we are limited to the full well capacity of the photodiode if it's all in one shot.

I'm not saying it's an unsolvable issue, just that having more DR does not necessarily automagically result in better images. IMHO
A better image is up to the photographer. The ability to capture that better image is up to the camera/lens. In theory, a perfect capture would allow you to not have to worry about those technical aspects while taking the photos. You could then do whatever you wanted in post.

I should have been more specific, this site is one of the better ones, its the others I am speaking of, sorry.

Guys, we're less than a week away now, and there's little to no information on this thing and lots of "it may be this, but might not be" going on. Anyone on the internet can take some shots with asterisks. What's going on? I am getting messages in my inbox from random people that I may or may not trust, as well. You guys have been very timid and overly cautious lately with little to offer. Also, you said weeks ago you'd be publishing an article about what's going on at Canon and continue to just ignore questions about that.
I'd be really interested into learning more about the politics and the situation at Canon :).

I would say camera / lens have a part in capturing better image data, all the rest is up to the photographer.
I agree with what you say apart from the caveat above, but I do not think you're actually replying to my point so not sure if we agree or not on that :)

Sony isn't giving their AF equally across their lineup, only a9iii has advantage over others, the rest is behind Canon.

I am really unsure about how this would work for stills. I haven't seen any real deep dive (just dumbed down explanations) into how this works without subsequent images. Global shutter I guess would get around that, but without global shutter - I don't know. it may even be DGO in video, but normal in stills, or normal and expanded DR in stills (with the expanded DR having cavaets).
If I get it right, DGO implementation in Canon's cinema cameras takes advantage of the dual pixel layout. One sub-pixel is read at a normal gain and another sub-pixel - with a higher gain for shadows. I guess it should work for stills too, but I think it'll also require a bit of additional processing and expansion of raw files to 16-bit depth.

I do not believe that's true. Where are you getting that information? As was pointed out earlier, parallax would be an issue with using the DPAF architecture to drive DGO. The Canon white paper makes no mention of it.

Edit: you're right, in your paper it's explained in more detail on the pages 4 and 5.

The two sequential 1/120 sec equal amplitude component signals are finally sent to a frame store thatimplements a blending of the two signals and then that singular composite signal is read out at theoriginal picture capture rate to which the camera had been set

That basically confirms my suspicion the DGO takes longer - it requires two separate readings.
So if Canon implements DGO in the R1 and/or R5II, it'll probably be a separate shutter mode for genres like landscape.
