This option controls whether
photographs can be taken only
when the camera is in focus (
focus
priority) or whenever the shutter-
release button is pressed (
release
priority) in single-servo AF. To select
single-servo AF, rotate the focus
mode selector to S.
Regardless of the option selected, focus will lock while the in-focus
indicator (
I ) is displayed.
If the subject leaves the selected focus point when dynamic-area
AF (
I; 0 76) is selected in continuous-servo AF (focus mode C;
0 74), the camera will focus based on information from
surrounding focus points. Choose the number of focus points from
9, 21, and 51 based on subject movement (note that only active
focus point is displayed in the viewfinder; the remaining focus
points provide information to assist focus operation).
