When AF-S is selected for viewfinder photography (0 97), 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).
Regardless of the option selected, if the in-focus indicator (
I) is
displayed when AF-S is selected for autofocus mode, focus will lock
while the shutter-release button is pressed halfway.
Focus lock
continues until the shutter is released.
This option controls how autofocus adjusts to sudden large
changes in the distance to the subject when AF-C is selected during
viewfinder photography (0 97).
