Can EOS R5 Mark II register dial assignments in custom modes?

[alaincoste]

Hello

I previously posted the question in the Gear Guide forum, and got no answer. Now I realise it was probably not the right one, so I post it here. Apologies for the duplicate !

I am interested in the EOS R5 Mk2, but I need to know the answer to a question before I buy it.
Is it possible to have different dial assignments in different custom modes ?
For instance I want C1 as true manual mode ; Quick control dial 1 will control ISO.
Then C2 will be "manual" mode with ISO auto ; and Quick control dial 1 will control exposure compensation.
Is it possible to assign ISO control in C1 and exposure compensation in C2 to the same dial ?
I read carefully the manual, but couldn't find a definitive answer.
Thanks in advance for your answers.

I already looked at it, but something is bothering me in this mode : setting is always a two times process, first chose the setting you want to change (with quick control dial 2) and then change the setting (with main dial). For me it is much more intuitive and handy to have a dial for shutter speed, a dial for aperture, and a dial for the "adjustment variable" (ISO or exposure correction, depending on the mode) : one time process, very fast and muscular memory works.

I have both the R5 series (classic and mark II) and by default, that is the way they are configured. When in Manual, the main dial controls shutter, dial 2 controls ISO, and dial 3 on the back controls aperture. The ISO control is right where my thumb is so I don't need to let ISO float, I utilize Exposure Simulation to dial it in.

Yes, this is true manual mode. It is one of the modes I want. But I want also a semi-auto mode where I manually set shutter speed and aperture, and let the camera set the ISO (auto-ISO). And in this semi-auto mode the dial which was setting ISO in manual must now be assigned to exposure compensation (which I wrongly named exposure correction in my previous posts).  So this dial must be assigned two different functions in my two modes. The modes can be C1 and C2 as I stated before, or possibly M and C1. I have seen that some people solve the problem by assigning ISO to dial 2 (for instance) and exposure compensation to the lens control ring, But I want to control what is for me the basis with the three dials of the camera, keeping the control ring for other functions (perhaps WB or select AF area or something else ...).

I really don't understand what you are after other than being able to have multiple dial configurations, one for each Custom mode. As mentioned, I abandoned manual mode when I went from film to digital some 20+ years ago. Modern cameras are pretty good at picking up a leg of the triangle, especially the R5 series.

Now, I fooled with the dials on my R5 II this evening and with the exception of the limited options of the main dial (see attached image), you can assign a function, register it and other settings to a Custom control (C1, 2, 3), then give the dial another function and assign it to another Custom control. So, in effect, one dial can serve as three different functions plus whatever you have set for the non-function settings. There may not be enough options for what you are trying to do, unlike the buttons, which are almost limitless.

Some crappy shots with my phone, but you can see, unlike the buttons, dials are limited in options.
