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

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.

Hello
Thank you for your answer, but those pages of the manual don't answer my question. They explain how to assign functions to buttons and dials, but my problem is to know if I can assign DIFFERENT functions to the SAME dial in different custom modes.
For instance, the manual says page 1052 :

"Different functions, for use when shooting still photos or movies, can be assigned to the same button"

Well, now I know that I can assign two different functions (one for stills, one for movies) to the same button. But what I want to do is assign 3 different functions (one for C1,one for C2,one for C3) to the same DIAL in still photos mode. Nowhere in the manual I could find the answer. Perhaps I didn't understand something... If somebody did this, or better understand the manual, I would be happy to hear him.

If it can’t be done via C modes it can be done by saving different CSD file configurations.

Hello, alaincoste!

One of my cameras is the R5 II, but I only customized one button and the lens control ring. I tested the button this evening by changing its assignment then registering each to a different Custom control number. That worked, so as I flipped through the C functions, that button took on the assignment that I had stored. I shoot in either Tv or Av and when I would exit C1, 2, or 3, my original settings were intact, if that makes sense.

I want my dials to stay at their default setting, so I didn't experiment with them and frankly, I didn't feel like resetting if I messed something up. I'm old and have very little patience 🙂 But TBH, I don't see why they wouldn't be the same. Even though I was able to do this with buttons, it would be nice if someone else could test their R5 II. I just tested with one button. I would hate for you to spend 4 grand and it not do what you want.

On a side note, even if it doesn't do the tricks you want, the R5 II is the most well rounded camera I have ever used. So much so that I haven't been tempted to over complicate things by re-configuring buttons. The default button/dial assignments have proven to be perfect for me. Plus, I use 7 different cameras and remembering button assignments slows me down, hah!

Hello John,
Sadly, CSD file configurations is not a solution for me as I need two or three modes I can change instantly by turning a dial. If I must go through the process of loading a CSD file every time I want to change the mode, this is not a practical way of doing things ...

Hello Newton,
Your answer brings a little hope to my quest !
I am old too, but as I'm a computer scientist, a little programming doesn't scare me.
The fact that you could assign different functions to the same button in different custom modes is a step in the good direction. Like you, I think it should be the same for dials, but the way Canon handle things (not all functions can be assigned to a programmable button for instance) makes me suspicious. I would not buy a R5mk2 if I cannot make it work the way I want. I hope that someone with ideas as iconoclastic as me will have tried to reassign the dials in different custom modes ...
Alain

I'm curious - does any camera other than the R5M2 have that capability? IOW does your current camera?
