Originally posted by Marc Sabatella More points means it more likely the camera will be *able* to choose to focus on the thing you wanted it to focus on. But there is never any guarantee it *will* focus on what you want - it can't read your mind. And the more choices you give the camera, the longer it might take to make the choice. If you want faster AF, first thing to do is stopping asking to the camera to waste time choosing. Either use center point mode, or the selectable focus point mode (not available on K-m).
You are right, i always use center or one of the 11 points. So in center focus mode, wich one is faster, KM or K20D?
