Shooting – Advanced Functions

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.

zIf 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.

zSome aperture values may not be available with certain zoom positions (p. 78).

zPlease 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.

zIn 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.
