I was taking photos this evening and the camera was working great and has been great since I purchased it a few months ago. Then I noticed the focus point is stuck in the top left even when there is a person in front of the camera. No matter what I do in settings it does not change. I have tried changing focus modes, turning the camera off and back on, and even removing the battery thinking it maybe just needs a "reboot". Has anyone had this happen before and what is the correction?
