Basic Operation

Power Switch

The camera operates only after the Power switch is set to <1>.
•
To save battery power, the camera turns off automatically after 1 minute
of non-operation. To turn on the camera again, just press the shutter
button. You can change the auto power-off time with the menu's [Auto
power off] setting (∆).
•
Immediately after shooting, if you turn the Power switch to <2>, the
access lamp may continue blinking for a few seconds while the CF card
records the image.
After the image recorded to the CF card, the camera turns off automatically.

Shutter Button

The shutter button has two stages. You can press it down halfway or
fully. The two levels of shutter button operation are as follows:
26
<1> : Set to this position when the
camera is in use.
<2> : The camera does not operate.
Set to this position when not
using the camera.

Halfway pressing

Pressing the shutter button down halfway
activates autofocusing (AF), and also
activates the automatic exposure (AE)
mechanism and sets the shutter speed
and aperture value.
The exposure (the combination of shutter
speed and aperture value) appears on the
LCD panel and in the viewfinder (˜).

Full pressing

This releases the shutter and shoots.
