I. CAMERA FEATURES AND OPERATION 8One-Shot AF: This mode is intended for use with stationary subjects. It locks focus uponcompletion of lens drive, allowing the photographer to recompose if desired. One-ShotAF is also recommended for maximum performance in extreme low-light situations.AI Servo AF: This mode is intended for use with moving subjects. It operatescontinuously up to the instant of exposure, and it also operates between exposures inburst mode shooting.In AI Servo AF, you can tell whether the AF system is tracking the subject by observingthe focus indicator in the viewfinder below the picture area. If the focus indicator doesnot light, the system is tracking. If it is blinking rapidly, the system is not tracking.Please note that this is slightly different from the camera's behavior in One-Shot AF. InOne-Shot, the focus indicator still blinks when the subject can't be focused, but it lightsup continuously when focus has locked.Canon provides two AF point selection methods: Automatic and Manual. The details ofeach method are described below.Automatic Focusing Point Selection (AFPS): The camera selects a focusing point foryou, choosing from all 45 points. AFPS behavior varies according to your choice offocusing modes:• When One-Shot AF is combined with AFPS, the camera typically selects the closestsubject with readable contrast. Since the subject may be large enough to cover severalfocusing points simultaneously, the viewfinder’s focusing point display may illuminateas many as 13 points simultaneously. If focus cannot be achieved, the in-focusindicator below the picture area blinks.• When AI Servo AF is combined with AFPS, the camera shuts off all focusing pointsexcept the central one until the subject has been identified. Once the camera hasstarted to track the subject with the center point, all 45 points are activated and thecamera is able to track movement not only towards or away from the camera, butanywhere the subject moves within the 45-point coverage area.Manual Focusing Point Selection (MFPS): The photographer selects the desiredfocusing point. When the camera is set to its defaults, only one or two focusing pointsare used. (To select 2 focusing points at once manually, use the Quick Control Dial toscroll up or down from the currently selected manual focusing point. When 2 focusingpoints are active, the camera evaluates both and selects the one with the mostreliable subject data. This can come in handy when photographing moving subjects.)The active area around a manually selected focusing point can also be expanded in twostages via Custom Function 17.
