3 Selecting AI Servo AF CharacteristicsN 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] for the following: When an obstacle cuts across the AF points or the subject tends to stray from the AF points, when you want to focus on a subject appearing suddenly, when the speed of a moving subject changes suddenly, or when the subject dramatically moves horizontally or vertically. 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 on 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 on 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 default setting is unable to track the target subject, setting [Tracking sensitivity] to [-2] may give better results (p.114). 110
