until you feel resistance.
• When you press the shutter-release button
halfway, the camera sets the focus and
exposure (shutter speed and aperture value).

on that subject. When the subject is in focus, the focus
areas (up to 12 areas) light in green.

• The camera has nine focus areas, and if it does not
detect the main subject, it automatically selects the
focus areas containing the subject closest to the
camera. When the subject is in focus, the focus areas
that are in focus (up to nine areas) light in green.
• When the digital zoom is in effect, the camera focuses
on the subject at the center of the screen, and the focus area is not displayed. When
the subject is in focus, the focus indicator (_8) lights in green.
• When the shutter-release button is pressed halfway and the focus area or focus
indicator flashes in red, the subject is out of focus. Change the composition and press
the shutter-release button halfway again.
2 Pressthe shutter-release button all the way,
i.e., press the button the rest of the way down.
• The shutter is released and the picture is recorded.
• If you press the shutter-release button with too much
force, the camera may shake, causing images to be
blurred. Press the button gently.
