I don't have one yet, a goal.
But reading literature and instructions and reviews a simple fact has occured to me.
The control ring on the RF lenses or the adapter for EF/EFs lenses makes manual or Aperture Priority really interesting, especially for those used to old manual lenses.

On the F-1 for example you set shutter speed by a dial on top of the body, the EOS R you do the same.
Here is the cool part.
On the F-1 you set the aperture on the lens and on the EOS R with all RF, EF and EFs lenses you can, if you choose, set the aperture the same way, on your lens.
This logical separation of functions is very intuitive rather than a bunch of dials on the body.

Perhaps others might have thought about this but it just makes those 2 actions so easy to differentiate like I did on manual cameras and lenses. Reach for the Lens for aperture control or the body for shutter control. Obviously these can be programmed as you wish but for all my EF/EFs lenses and future RF lenses to do this is really cool.

I have had my EOS R for a little over a week. I have not yet figured out what I want the "extra" ring on the lens (or adapter) to do for me. Slightly off topic: the EOS R does not have built-in GPS; it is on my wish list for the next Canon mirror-less camera. (The in-flash-shoe GPS unit (GP-E2) works, but it's kind of clunky.) I like that the camera and its 24-105L are a bit smaller than my 5DSR with its 24-105L. I have not yet been out shooting with it, so I can't comment on the picture quality; I would expect it to be on a par with 5D IV -- they have the same sensor. BTW, the Digital Picture (https://www.the-digital-picture.com) has a review of the EOS R.

You might try to do as I was thinking with the control ring on the lens becomes the aperture ring as of old.
Just seems intuitive and logical.

Yes, it does, but I'm not sure that's what I want.

I always thought that the best idea would be to put TWO dials up by the shutter release...one for shutter one for aperture.....would be the most convenient situation. It's ridiculous the way it is now on my 7DII with one by the shutter release and the other in an awkward position on the back of the camera.

Canon has solved this problem with the new R camera system.
The RF lenses have an extra ring on them that can be programmed as the aperture ring and you can program a wheel on the body to be the shutter control. Sort of like old manual cameras used to be.
The great thing is with the adapter ALL your EF lenses also get this feature with the R cameras.
So as you get new Canon equipment consider the R system to get this feature will ALL your current and new EF/EFs lenses.
Pretty sweet and unique to Canon.

Then you should buy an EOS R or an M5.... both have dual dials on top... a "vertical" one for the shutter, and the other "horizontal" one for the aperture. Thevertical "main dial" is right behind the shutter release, while a the second horizontal dial under your thumb can be assigned to handle the function of your choice.

But, honestly, I don't know why you find the rear control dial "awkward" on 7DII. Canon has been using that arrangement on cameras since the days of film... every Canon model I've shot with for the past twenty years has had it. I prefer it over the single dial on top/press a button first method used on some cameras... or the multi-directional buttons on the rear of some others.

OP, I don't have an EOS R (few people do yet), but from what I can see in the user manual (below), the control ring on the lens (and on one of the EF/EF-S lens adapters) cannot be used for aperture, shutter or ISO while the camera is in Manual exposure mode. It does appear to be usable to control aperture in Av mode or shutter in Tv mode..... Is that correct? (As a side note... I notice the EOS R user manual has grown to 650+ pages! And I thought the 1DX and 7DII manuals were big! Also, if you don't care for the GPS module, if you have one you can instead use a Bluetooth-enabled smart phone to geotag images.)
