shutter button halfway.

Helps avoid missing sudden photo opportunities, because 

the camera constantly focuses on subjects until you press the 

shutter button halfway.

constantly.

This mode helps avoid missing shots of subjects in motion, because the 

camera continues to focus on the subject and adjust the exposure as long 

as you press the shutter button halfway.
