Setting the Aperture
When you set the aperture in the aperture-priority
AE mode, the camera automatically selects a
shutter speed to match the brightness.
Selecting a lower aperture value (opening the
aperture) allows you to fade the background and
create a beautiful portrait. A higher aperture value
(closing it) brings the entire range from foreground
to background into focus. The larger the aperture
value, the greater the range of the image brought
into clear focus.
z If the shutter speed shows in red on the
LCD monitor, the image is
underexposed (insufficient light) or
overexposed (too much light). Adjust the
aperture value using the left or right
button until the shutter speed display
turns white.
z Some aperture values may not be
available with certain zoom positions
(p. 78).
z When the AF frame is set to FlexiZone,
you can switch between aperture value
and AF frame each time the SET button is
pressed (p. 82).
z Please note that camera shake becomes a
factor with larger aperture values that slow
down shutter speeds. If
(camera shake
warning) appears on the LCD monitor,
secure the camera to a tripod before
shooting.
z In this mode, the shutter speed range with
synchronized flash is 1/60 second to 1/500
second. The aperture value setting may
therefore be changed automatically to
match the synchronized flash speed even
if its value was set previously.
