Is there any way to save settings and toggle back and forth??

[Ronnycharlas]

In other words, is there a way I can move quickly from shooting portraits to action photos (Muay Thai/boxing) in a matter of seconds by toggling my iso/shutter speed/etc settings from one to the other and vice versa without needing to completely re-enter all of my settings every time the “genre” changes?

Specifically, I’m just learning my way around a 5D Mark IV, using a 24-105mm lens which works well in both of these environments, so the lens won’t be the issue here.

Thanks in advance!

You can define Custom Shooting Modes on the shooting mode dial.  Download a copy of the full User Manual from Canon to learn how to set it up.  It is not a complicated process.  The manual will tell you where to go in the menus to save your settings.
