Automatic focusing
When
you
press the shutter button,
sound
waves
(at
frequencies
beyond
our range
of
hearing) are sent
to
the
central part
of the scene.
A
built-in
computer measures the
time
it takes
the soundwaves
to
reach the scene
and the echo
to
return
and
uses this
measurement
to
provide the correct
lens setting.
.
Be
sure
the
sound waves
have
a
clear
path
to your subject.
lf
an
object
near the central part of the
scene prevents
lhe
sound waves
from
reaching
your
subject,
the
lens
will focus on
that
object, causing your
subject
to
be unsharp.
.
When
photographing more than one
person,
focus and
illumination are
improved if
everyone is about the
same
distance from the
camera.
