The “main dial” near the shutter button.
Question: @Ray-uk I’m a newbie. What on/off switch are you referring to? I’m not quite sure what you mean and I’ve searched the manual for this. Thanks
He means the "Quick Control Dial" on the back which has a sliding lock switch below it. That lock switch has no effect on the main dial near the shutter button.
The main dial on my Canon 5D Mark IV is not working to make adjustments while in any of the modes. I can hit the quick (Q) button and make adjustments or use it in settings other than went in in a shooting mode. Any ideas?
When the viewfinder display is active, does an "L" appear whenever you try to use it? If so, the problem is the lock switch.
