Recently I started using the center focusing point, and re-composing as my primary focus method. As I was reviewing my pictures from the last few weeks, I noticed that in a lot of cases I missed the focus, and my overall keeper rate had gone down. I understand the advantages of using the center focus when dealing with razor-thin DOF, or in challenging shooting conditions; however, I find myself missing the shot because I am too busy trying to focus on something and recomposing.
What percentage of time does everyone use the manually selected focus point vs. using all of the available focus points and letting the camera make the focusing decision? To provide some background, I shoot just about everything, and my equipment is a 5d MK II, 24-105, and a 70-200F4.
