The first mode is called One Shot (Canon) or AF-single (Nikon). In this Mode, as you begin to hold the shutter down, the camera will focus on your subject, light up in the viewer, and lock. That is to say the focus is now set. You can either take the photo as is (by completely depressing the shutter), or move your camera first to recompose.
