So basically I can get the camera to eye focus with the center button but the green box only stays highlighted for a second or two. At first I was using it with face recognition and it would go from eye focus straight to the big box to focus on the whole face. I turned off the face recognition and now it only highlights the eye for a second or two. I've tried it multiple times in different situations and still the same results. Is this normal or am I doing something wrong? Thank in advance for the help/suggestions.
