Focus Settings
With the mode dial set to A-REC, a choice of three autofocus
modes is available. In addition, M-REC mode offers a selection of
manual focus settings.
Autofocus settings
The autofocus settings available in M-REC and A-REC modes are
listed in the chart below.
When the mode dial is set to A-REC or M-REC, the autofocus
mode can be changed using the
button. The setting changes
each time the button is pressed, cycling through the focus modes
in the following order:
NO ICON (AUTO)
Autofocus
In autofocus and macro close-up modes, the camera automatically adjusts
focus according to the distance to the subject. When the LCD monitor is
on, the camera focuses continuously up to the moment the shutter-release
button is pressed (continuous AF). When the monitor is off, the camera
only focuses when the shutter-release button is pressed half way (single
AF). Focus is fixed when the shutter-release button is pressed half way, and
remains fixed as long is the shutter-release button is held down (focus lock).
Using the Buttons (A-REC, M-REC): Focus Settings
Macro Close-up
When using macro close-up, it is recommended that you frame photo-
graphs in the LCD monitor.
Macro close-up can be used at ranges as short as 7cm (2.8in.) when the
camera is zoomed to the middle optical zoom position. When the camera
is zoomed to a position suited to such close-range photography, the macro
icon (
) in the LCD monitor will turn yellow.
While the flash can be used with a focus mode of “Macro Close-up,” it may
sometimes be unable to light the entire subject. When using the flash, take
a test picture and verify the results in the LCD monitor.
