A Full Auto Techniques (Scene Intelligent Auto)

Recomposing the Shot
Depending on the scene, positioning the subject toward the left or right
to include a balanced background will result in a picture with better
perspective.
In the <A> mode, pressing the shutter button halfway to focus on a
still subject will lock the focus on that subject. Recompose the shot
while keeping the shutter button pressed halfway, and then press the
shutter button completely to take the picture. This is called "focus lock".
Shooting a Moving Subject
In the <A> mode, if the subject moves (distance to camera changes)
during or after focusing, AI Servo AF will take effect to focus on the
subject continuously. (The beeper will continue beeping softly.) As long
as you keep the Area AF frame positioned over the subject while
pressing the shutter button halfway, focusing will be continuous. At the
decisive moment, press the shutter button completely to take the
picture.
