AF-C is continuous, when you focus on an object, holding it (half-)pressed, it will continue to try to keep whatever is in the focus areas in focus, whether you move or the subject moves, or you move the focus area to another subject.F-S is single, when you focus on one object and hold it (half-)pressed, it will keep the focus where it locked. This includes any movement of you/camera, and the movement of the subject. This is used for recomposing (once you lock focus, you can rotate the camera and the object will stay in focus).
