Framing Photographs in the
Monitor
Press the a button to frame pictures in the monitor. The following
options are available:
•
Tripod
(
h
): Choose when the camera is mounted on a tripod
(
0
55). 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
(
g
): Choose when taking hand-held shots of moving
subjects, or when framing photographs at angles that make it
difficult to use the viewfinder (
0
59). Camera focuses normally
using phase-detection autofocus.
A
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.
A
Flicker
You may notice flicker or banding in the monitor during live view or
when shooting movies under certain types of lighting, such as
fluorescent or mercury-vapor lamps. Flicker and banding can be
reduced by choosing a
Flicker reduction option that matches the
frequency of the local AC power supply (
0
330).
