Okay, like I have said before I have a single AF square. When it locks in on a subject, other focus points surrounding it will come up. It is a single point, not expanded.
Okay, it is one of 2 things. 1. I did/am not using the corrects terminology, words or not explaining what I mean well enough or 2. you are incorrect. I can use the single AF point and it will expand but you have to go into the menu and change a set...
Just to make sure I am understanding what you are saying, if I am in single point AF in Servo, the single point will not expand to 3 or 4 points together and track the subject I am foucused on?
