Av: Setting the Aperture
The aperture adjusts the amount of light that passes through the lens. Selecting a lower aperture value (opening the aperture) allows you to blur the background. A higher aperture value (closing it) brings the entire range from foreground to background into focus.
When you set the aperture in the aperture-priority AE mode, the camera automatically selects a shutter speed to match the brightness.
1. Turn on the camera in shooting mode, and turn the shooting mode dial to 'Av'.
- The aperture value will display on the LCD screen
2. Select a value by rotating the multi control dial.
- The aperture value on the LCD screen will change.
3. Shoot the image.
- The correct exposure has been set if the shutter speed and aperture value show in white.
Aperture Value Display
The larger the aperture value the smaller the lens opening, allowing less light to enter the camera. Below are the available aperture values:
F2.8 F3.2 F3.5 F4.0 F4.5 F5.0 F5.3 F5.6 F6.3 F7.1 F8.0
- Some aperture values cannot be selected depending on the zoom position.
- If the image would be underexposed (too dark) or overexposed (too bright) and the correct exposure cannot be obtained, with the shutter button pressed halfway, the shutter speed display on the LCD monitor turns red. Turn the multi control dial to adjust the aperture and display the shutter speed in white characters on the display.
- On the Shooting menu, set [Safety Shift] to [On]. The aperture is adjusted automatically to give pictures the correct exposure.
- Pressing the
 button places the camera in exposure correction mode. Each time you press the button, you change modes. However, this is different under Manual focus.
- In this mode, the maximum shutter speed with synchronized flash is 1/250 second. The aperture value setting may therefore be changed automatically to match the synchronized flash speed even if its value was set previously.
Safety Shift
With Tv and Av modes, if [Safety Shift] is turned [On] in the Rec. menu, the shutter speed or aperture value is automatically adjusted for the correct exposure when it cannot be otherwise obtained. Safety Shift is disabled when the flash is enabled.
