This is the possible Canon RF mount camera roadmap [CR2]

The second button is set to "eye detection AF". I only used it for stills, so no, I don't know the difference between these two modes.
That is correct. The first back button focus is for regular autofocus (using chosen AF point), the second one for eye detection autofocus. Of course, most of the times, you only press one of them, but when you want to isolate your subject in a crowd, your eye detection AF can't know who you want to photograph, so you have to chose with the first BB AF before you use eye detection AF. Same technique when you want to focus on the eyes of that otter hidden in the bushes: you know where it hides, but you have to "show it" to your AF using the first button. Then, the second button finishes the job in an instant.
It might seem complicated because I explain poorly, but after I set it up on my friends R5, it took me only a few minutes to completely get use to it.
Much obliged, hope I can help despite my poor use of the english language!
Fair enough, cheers for the info always good to get another point of view, Looks like they will have you covered then, for the future.
Ok, so turns out you and everyone else can dismiss me saying the 15-35 wasn't as good on the R/RaWhile I'm no expert on this (or on many other things I talk about), I wouldn't think that IBIS would make the corners any worse than they would have been (due to handhold shake) without it. But when Canon says they're getting some extremely high #stops of dual IS (which I often have seen measured by 3 or so less stops when user tested) I would strongly assume that it is measured in the center of the sensor, while the corners of the sensor for an extreme wide angle view would be still be improved, but by much less than the center.
My Ra came back from CPS repair yesterday for another issue (sensor cleaning was overly loud), and they replaced the circuit board. Corners at 15mm/infinity and 35mm/MFD/2.8 on the Ra are both sharp like the R5 now. Definitely something I am GLAD to be wrong about. Will keep the Ra now as backup and 2nd body. Thanks for the conversation, though, and for holding to the logic that it was more likely an issue with the R than an improvement with the R5 sensor design. Now I can go back to worrying about how these lenses will look on the 90mp R 
I know, and I'm coming from a 7d MkII! Autofocus, when set up right, is downright cheating!
Hmmm...I'm thinking the market is HUGE IF using a smaller sensor saves Canon a ton of money. As I understand chip development, there are many more APS-C sensors per wafer than full frame sensors.
Me neither, but I think it has been all quiet ;D - But thanks, will def. look into that
I can pretty much confirm it doesn't work on an RP. Even after assigning the eye detection to the splat button, it won't work. But I love it on my R5.
But does the R and RP even have Eye Detection/Focus..? Think it was introduced with the R5 and the R had "Face Detection" at most
Or that was basically what you said yes

I'm glad the servicing of the Ra fixed your problem. I don't see how a new circuit board in itself could have caused that particular optical issue, unless there was a broken clip or two on the board holding down the sensor or it was otherwise misaligned. I would assume that their replacing it and reassembly caused them to make sure all clips and shimmed alignments of it (and the contained sensor) were correct. That would easily fix considerable optical errors at the corners. I've seen teardowns of Sony (and other) bodies showing broken sensor attachment clips and significant misalignment of the sensors relative to the mount. After years of using camera bodies & lenses and the inevitable bumps they get, I'm amazed that they can keep their alignment as well as they do.Ok, so turns out you and everyone else can dismiss me saying the 15-35 wasn't as good on the R/Ra
I also enjoyed our conversations on this, and yes ... we can now go back to worrying about how these lenses will look on the 90(?)MP R5s
No, you're correct. I said the wrong thing, and that is because I was confused. Thanks for the correction!But does the R and RP even have Eye Detection/Focus..? Think it was introduced with the R5 and the R had "Face Detection" at most

The RP has the eye detection autofocus, and it works pretty well on a still or slow moving subject. Forget a running kid, though! I use it a lot with portraits.But does the R and RP even have Eye Detection/Focus..? Think it was introduced with the R5 and the R had "Face Detection" at most

How much cheaper could an RP be if it had an APS-C sensor instead of a FF sensor? Probably not much.
