Just pointing the centerpoint where i want the focus to lock on, and then move to cover what i want to have in the photo, keeping the focus locked. Never trust camera doing automatic selection where to focus, and when it gets it wrong, i'm wasting time to do it over again and possibly missing the moment. | |

Say, for example, your subject is indoors, standing next to an open door with daylight coming in, so part of the frame is brightly lit and the rest in relative darkness. Spot focusing will probably be fine, area autofocusing might get confused. | |
