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).

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.

ALocking Focus with the BButton

During viewfinder photography, focus can be locked using either of the Bbuttons 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 Bbutton 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.
