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 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
x
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 52). Camera focuses normally
using phase-detection autofocus.

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.
