Framing Photographs in
the
Monitor
Press
the
~
button
to
frame pictures in
the
monitor. The
following
options are available:
•
Tripod
(~):
Choose when the camera
is
mounted
on a
tripod
(CJ 49).
You
can zoom in on
the
image displayed in
the
monitor
for precise focus, making this
option
suitable for static subjects.
Contrast-detect autofocus can be used
to
compose photographs
with
the
subject positioned anywhere in the frame.
•
Hand-held
(~~):
Choose
when
taking hand-held shots
of
moving
subjects, or when framing photographs at angles
that
make
it
difficult
to
use
the
viewfinder
(CD
52). Camera focuses normally
using phase-detection autofocus.
B Phase-Detection Versus Contrast-Detect
AF
The
camera
normally uses
phase-detection
autofocus,
in
which focus
is
adjusted
based
on
data
from a special focusing sensor.
When
Tripod
is
selected
in
live view, however,
the
camera
uses
contrast-detect
autofocus,
in
which
the
camera
analyses
the
data
from
the
image
sensor
and
adjusts
focus
to
produce
the
greatest
contrast.
Contrast-detect
autofocus
takes
longer
than
phase-detection
autofocus.
