To save battery power, the camera turns off automatically after 1 minute of non-
operation (auto power off /
→p.142). To turn on the camera again, just press the
shutter button halfway.

Immediately after shooting, if you turn the < > switch to < >, the access lamp
may continue blinking for a few seconds while the CF card records the image.
After the image is recorded in the CF card, the access lamp will turn off and the
camera will turn off.
The shutter button has two stages. You can press it down halfway or fully. The two levels of
shutter button operation are as follows:
Halfway pressing ( )
Pressing the shutter button down halfway activates
autofocusing (AF), and also activates the automatic
exposure 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.
If you press the shutter button halfway and ( ) elapse, press it halfway again and wait a
moment before pressing it fully to shoot. If you press the shutter button fully without
pressing it halfway first or if you press the shutter button halfway and then press it fully
immediately, the camera will still take a moment before it shoots.
No matter what state the camera is in (image playback, menu operation, image
recording, etc., except during direct printing), pressing the shutter button halfway will
instantly make it ready for shooting.
