Caution: 3D-Tracking and Subject Tracking
The camera may be unable to track subjects that:
are similar in color, brightness, or pattern to the background,
change visibly in size, color, or brightness,
are too large or too small,
too bright or too dark,
move quickly, or
are obscured by other objects or leave the frame.
Tip: s: The Center Focus Point
In all AF-area modes except [Auto-area AF], [3D-tracking], and [Subject-tracking AF], a dot appears
in the focus point when it is in the center of the frame.
Tip: Choosing the AF-Area Size: "Wide-Area AF (C1)" and "Wide-Area AF (C2)"
When [Wide-area AF (C1)] or [Wide-area AF (C2)] is selected for [AF-area mode], the size of the
focus area can be chosen by holding the focus-mode button and pressing 1, 3, 4, and 2.
Tip: Quick Focus-Point Selection
For quicker focus-point selection, choose [Alternating points] for Custom Setting a4 [Focus points
used] to use only a quarter of the available focus points. Selecting [Alternating points] does not
affect the number of points available for [Pinpoint AF].
If you prefer to use the sub-selector for focus-point selection, you can choose [Select center focus
point] for Custom Setting f2 [Custom controls (shooting)] > [Sub-selector center] to allow the
center of the sub-selector to be used to quickly select the center focus point.
