exposure. This is called auto focus.
NOTE: The green brackets surround the area(s) in focus to
help you ensure that the camera is focused on the correct
subject. If the camera keeps focusing on the wrong
subject, try using Spot focus (see Auto Focus Area on
page 74).

had difficulty focusing on the subject or because the focus

Shutter button and try one of the following:
