T3i-how to choose AF 9 points?
I read some posts below and made me think AF that i have never thought about. If i choose 9 AF points all lite up; does it mean the camera will automaticllay choose the best "ONE" point as a main focus point?
If i choose 9 AF points with a nifty fifty; sometimes focus is good and sometimes is no good? Would this explain the why? If so, would choose center focus with nifty fifty be better?
If i choose center focus and say F4 and up, would the close subjects surround center be out of focus?
Last, how wide is the center focus parameter?
Thanks and much appreciated for some Christmas family photos.
