This section describes how to take pictures using program AE (mode [P]).
To allow the camera to adjust both shutter speed and aperture for optimal exposure, set shutter speed and aperture to [A].
[P] will appear in the display.
If the subject is outside the metering range of the camera, the shutter speed and aperture displays will show "–––".
Program Shift
If desired, you can rotate the front or rear command dial to select other combinations of shutter speed and aperture without altering exposure (program shift).
Shutter speed
Aperture
Program shift is not available if the attached flash supports TTL auto, or if an auto option is selected for [IMAGE QUALITY SETTING] > [DYNAMIC RANGE]. To cancel program shift, turn the camera off.
Press the shutter button halfway to focus and the rest of the way down to shoot.
Focus.
Frame the picture with your subject in the center of the display and press the shutter button halfway to focus.
If the subject is poorly lit, the AF-assist illuminator may light.
If the camera is able to focus, it will beep twice and the focus indicator and frame in focus will glow green. Focus and exposure will lock while the shutter button is pressed halfway.
Focus frame
Focus indicator
If the camera is unable to focus, the focus frame will turn red, 
will be displayed, and the focus indicator will blink white.
Shoot.
Smoothly press the shutter button the rest of the way down to take the picture.
