d Program AE
¡ If “30"” and the maximum aperture blink, it indicates
underexposure. Increase the ISO speed or use flash.
¡ If “8000” and the minimum aperture blink, it indicates
overexposure. Decrease the ISO speed or use an ND
filter (optional) to reduce the amount of light entering the
lens.
Differences Between <d> and <
1> (Full Auto)
¡ In both modes, you can freely change the automatically-set shutter
speed and aperture combination (program).
¡ In the <d> mode, you can set or use the functions below, but not in the <
1> mode.
Shifting the Program
¡ In Program AE mode, you can freely change the shutter speed and
aperture value combination (program) set by the camera while
maintaining the same exposure value. This is called program shift.
¡ To do this, press the shutter button down halfway, then turn the <
6>
dial until the desired shutter speed or aperture value is displayed.
¡ Program shift is canceled automatically after the image is captured.
¡ If you are using a flash, you cannot shift the program.
