 Setting the Aperture

The aperture adjusts the amount of light that 

passes through the lens. 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   

or   button until the shutter speed display 

turns to white.

z

Some aperture values may not be available 

with certain zoom positions (p. 78).

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.

The larger the aperture value, the smaller the 

lens aperture.
