3 Selecting AI Servo AF Characteristics (For a Subject) Case 1: Versatile multi purpose setting Default settings • Tracking sensitivity: [0] • Accel./decel. tracking: [0] • AF pt auto switching: [0] Standard setting suited for any moving subject. Works with many subjects and scenes. Select [Case 2] to [Case 6] in the following cases: when obstacles enter AF points, when the subject tends to stray from AF points, when you want to focus a subject that suddenly appears, or when the subject moves dramatically up, down, left, or right. Case 2: Continue to track subjects, ignoring possible obstacles Default settings • Tracking sensitivity: [Locked on: -1] • Accel./decel. tracking: [0] • AF pt auto switching: [0] The camera will try to continue focusing the subject even if an obstacle enters the AF points or if the subject strays from the AF points. Effective when there may be an obstacle blocking the subject or when you do not want to focus the background. If an obstacle gets in the way or if the subject moves away from the AF points for a prolonged period and the focus on the target subject is lost with the default setting, setting [Tracking sensitivity] to [Locked on: -2] may give better results (p.88). 84
