You can change default camera operation of constantly focusing 
on subjects it is aimed at, even when the shutter button is not 
pressed. Instead, you can limit camera focusing to the moment 
you press the shutter button halfway.
 
Press the [
] button, 
choose [Continuous AF] on the 
[ ] tab, and then choose [Off] 
On
Helps avoid missing sudden photo opportunities, 
because the camera constantly focuses on subjects until 
you press the shutter button halfway.
Off
Conserves battery power, because the camera does not 
focus constantly.
