EOS R5C Mapping the Iris

[kikokiko12]

Does anyone know how I can map the iris to my selection dial that is located to the right of the lcd screen when I am in video mode?  It looks like I can only map it to the top two dials or a control ring on a lens adapter.  However, I wanted it on the selection ring to mimic how I have it when shooting stills.  Any help is greatly appreciated.

If you are referring to Aperture Control, then you can use the Customize Button Menus to change the functionality of the Main Dial and the Rear Dial.

I've checked the manual and the menu several times, however, it does not seem possible to map the aperture control (Iris) to the selection dial on the back of the camera.  It can only be mapped to the grip control dial, or the top control dial.  Those options are located in menu #4 of the system setup menu.  Under the Assignable Buttons menu it does not allow you to map any controls the back selection dial either.

I think you’re correct.  The video mode does not allow it.
