Av: Aperture-Priority AE
In this mode, you set the desired aperture value and the camera sets the shutter speed automatically to obtain the standard exposure matching the subject brightness. A higher f/number (smaller aperture hole) will make more of the foreground and background fall within acceptable focus. On the other hand, a lower f/number (larger aperture hole) will make less of the foreground and background fall within acceptable focus.
Av stands for Aperture value (aperture opening).
(With a low aperture value: f/5.6)
Sharp foreground and background
(With a high aperture value: f/32)
Set the Mode dial to Av.
Set the desired aperture value.
- Turn the dial to set it.
Focus on the subject.
- Press the shutter button halfway.
- The shutter speed is set automatically.
Check the display and shoot.
- As long as the shutter speed is not blinking, the standard exposure will be obtained.
If the “30"” shutter speed blinks, it indicates underexposure.
Turn the dial to decrease the aperture value (open the aperture) until the shutter speed blinking stops or set a higher ISO speed.
If the “1/4000” shutter speed blinks, it indicates overexposure.
Turn the dial to increase aperture value (close the aperture) until the shutter speed blinking stops or set a lower ISO speed.
Aperture value display
- The higher the value, the smaller the aperture opening will be. The aperture value displayed varies depending on the lens. If no lens is attached to the camera, “F00” will be displayed for the aperture.
The aperture changes only at the moment you shoot, and it remains open at other times. For this reason, the depth of field shown on the screen looks narrow, or shallow. To check the area in focus, assign  (depth-of-field preview) to a button and press it.
- The larger the aperture value, the wider the area in focus, from the foreground to the background.
- The depth-of-field effect is readily apparent on images as you press the button assigned to depth-of-field preview.
- Exposure is locked (AE lock) as you hold down the button assigned to depth-of-field preview.
