If focus cannot be achieved, the focus indicator <
o
> in the viewfinder
will blink. If this occurs, the picture cannot be taken even if the shutter
button is pressed completely. Recompose the shot and try to focus again
or see “When Autofocus Fails” (p.140).
If [

is achieved.
After achieving focus with One-Shot AF, you can lock the focus on a
subject and recompose the shot. This is called “focus lock”. This is
convenient when you want to focus on a peripheral subject not covered
by the Area AF frame.
