A MODE: APERTURE PRIORITY
In A mode, you select the aperture and the camera automatically sets
the shutter speed required for proper exposure.
1. Set the command switch to ASM.
2. While pressing the mode button, turn the control dial until 'A '
blinks in the data panel.
The aperture priority mode is selected when you release the
mode button.
3. Turn the control dial to select the aperture.
If 2000 or 2 blinks in the data panel, the required setting is beyond
the camera’s shutter speed range. Turn the control dial until the
blinking stops. (See “Trouble Shooting”)
