Seems like I should have noticed this before. On the far left side of the viewfinder on my Canon 6D is a warning icon ("!"). It appears to be adjacent to the battery icon which is fully charged. So, I am stumped as to what the warning is for. Thank you so much.
I believe that it means you changed a setting somewhere. Its just a reminder that something has changed.
Hmmm...that seems odd since we all are constantly changing various settings under different shooting conditions.
Just had a thought...the warning icon (adjacent to the battery icon) that I referred to in my post above might simply be a reminder to keep an eye on the battery charge. If someone could verify this, I would appreciate it. Thank you.
