Operation and Viewfinder Focus Signals
Set to AF mode, the camera focuses automat¬
ically when the shutter-release button is
pressed partway down. With most subjects,
focus is rapidly set: the viewfinder displays a
focus confirmation signal and the picture can be
taken.
The AF system is capable of focusing on both
still and moving subjects. With moving sub¬
jects, focus is adjusted continuously according
to changes in subject position; in addition. Pre¬
dictive Focus Control improves autofocus oper¬
ation for moving subjects that are approaching
the camera by automatically compensating for
the change in subject position that occurs dur¬
ing the shutter-release sequence.
