The shutter release button works in a two-step action as follows.
Press halfway
This refers to pressing the shutter release button gently to the first position. This
locks the focus setting and exposure. The green focus frame lights on the display
when the shutter release button is pressed halfway and the subject is in focus. If
the subject is out of focus, the frame turns white.
Press fully
This refers to pressing the shutter release button all the way down to the fully
depressed position. This takes a picture.
