Program shift area

★When the Program line is shifted, the aperture value changes along with the shutter speed to maintain the proper exposure.

★If a correct exposure cannot be obtained, the shutter speed and aperture value blink. In such cases, the pictures can be taken but they may turn out too bright or too dark.

Program Shift (PH/PL)

You can change the shutter speed and aperture by turning the front and rear dials in the “P” (Program AE) mode. In order to avoid blurred images (shake while releasing the shutter), or to open the aperture, change to “ PH” (high speed). For slower shutter speeds and wider depth of field, change to “ PL” (low speed). This function allows you to make these changes quickly.

1. You can choose either aperture or shutter-speed to give priority in

program line shift. Custom settings (C-14 on page 94)

2.Increment of the aperture and shutter speed can be set at either 1/3 or

1/2-stop. Custom settings (C-01 on page 93)
