The Shutter-Release Button
The camera has a two stage shutter-release button. The camera focuses when the but-
ton is pressed halfway; focus locks until the button is released. To take the picture, press
the shutter-release button the rest of the way down.
4 Focus
Press the shutter-release button halfway to focus.
If the camera is able to focus on the subject in the
center focus area, a beep will sound and the in-fo-
cus indicator (
●) will appear in the viewfi nder (if
the focus indicator blinks, the camera was unable
to focus using autofocus). Focus will lock while
the shutter-release button is pressed halfway.
If the subject is dark, the AF-assist illuminator may
light to assist the focus operation.
5 Check exposure
In exposure mode P (programmed auto), the
camera automatically sets shutter speed and ap-
erture when the shutter-release button is pressed
halfway. Before shooting, check the shutter-
speed and aperture indicators in the viewfi nder.

current settings, one of the following indicators
will be displayed.
