AF-S focus mode: Focus locks automatically when the in-focus
indicator appears, and remain locked until you remove your
finger from the shutter-release button.
Focus can also be
locked by pressing the center of the sub-selector (see above).
3 Recompose the photograph
and shoot.
Focus will remain locked
between shots if you keep the
shutter-release button pressed
halfway (AF-S) or keep the center of the sub-selector pressed,
allowing several photographs in succession to be taken at the
same focus setting.
Do not change the distance between the camera and the subject
while focus lock is in effect.
If the subject moves, focus again at the
new distance.
A Locking Focus with the B Button
During viewfinder photography, focus can be locked using either of the
B buttons in place of the shutter-release button (0 99). If AF-ON
only is selected for Custom Setting a4 (AF activation, 0 309), the
camera will not focus when the shutter-release button is pressed
halfway; instead, the camera will focus when an B button is pressed,
at which point focus will lock and remain locked until either B
button is pressed again. The shutter can be released at any time,
regardless of the options selected for Custom Settings a1 (AF-C priority
selection, 0 307) and a2 (AF-S priority selection, 0 308), and the in-
focus indicator will not be displayed in the viewfinder.
