Selecting a shooting mode
Selecting a shooting mode
• The shutter speed may become slower depending on the aperture value.
When the shutter speed is slower, use a tripod.
• To blur the background more, use a telephoto lens or a lens that is
equipped with a smaller aperture value (bright lens).
• You can check the approximate blurring of the image before recording
using the preview button.
2 Select the aperture value (F-
number) with the front or rear
control dial.
• Smaller F-number: The foreground and
background of the subject are blurred.
Larger F-number: The subject and its
foreground and background are all in
focus.
• You cannot check the blurring of an
image on the LCD screen or in the
viewfinder. Check the recorded image
and adjust the aperture.
• When the camera judges that the proper
exposure is not obtained with the
selected aperture value, the shutter
speed flashes. In such cases, adjust the
aperture again.

3 Adjust the focus and shoot the subject.
The shutter speed is automatically adjusted to obtain correct exposure.
