Sports AF: Custom Settings, Continued a3: Focus Tracking with Lock-On This menu contains two options: [Blocked Shot AF Response] and [Subject motion]. ■ Blocked Shot AF Response If AF‑C is selected for AF mode, focus tracking with lock-on will prevent the camera refocusing when your subject is briefly obscured by another object, ensuring that it will continue to track the main subject once the obstacle has moved away. Choose the length of time before the camera refocuses from [1 (Quick)], [2], [3], [4], and [5 (Delayed)]. Lock-on applies only while the camera is focusing; to focus at a new distance without waiting for lock-on to end, re-initiate autofocus. The camera will track and focus on objects at the same distance as the main subject. High values (slow response) make the camera slow to refocus on obstacles when the shot is blocked. Select low values (quick response) to quickly refocus on subjects passing in front of the camera and for improved response when switching rapidly from one subject to another. Main subject Obstacle ■ Subject Motion Choose how the camera tracks subjects in motion. Choose [Steady] for subjects approaching the camera at a steady pace, like sprinters or race cars on a track, [Erratic] for long or triple jumpers and other subjects prone to sudden stops and starts. a4: Focus Points Used Choose number of focus points available for manual focus-point selection from the options below. Choosing [27 points] or [15 points] speeds focus-point selection. 105 points 27 points 15 points Note that the groupings available when [Group-area AF (C1)] or [Group-area AF(C2)] is chosen for AF-area mode vary with the dimensions of the group. 11
