As I age I believe my memory is slipping. I bought a R7 toward the end of last year. So far I've been practicing with it shooting birds, mostly in my back yard. I'm pleased with it overall, of course I was also pleased with my 7DII and all my previous DSLRs. But as I have altered the set-up I have somehow set it to, what I would call, "continuous autofocus." I use back-button focusing (two buttons dedicated to it). When I press either of these buttons (AF-On or *) and achieve focus if I release the button it continues to focus. When I noticed this I found that I can just turn the camera on and it starts focusing. I have looked in the advanced manual, looked at videos, etc., and still can't find how to turn this off. I am set for "Servo." Can someone give me some advice?
