Program - P
Program exposure is set with the exposure-mode dial (p. 50). The program AE uses luminance and focal-length information to calculate exposures. This allows the photographer to shoot without wor- rying about exposure settings. The shutter speed and aperture values of the exposure are displayed on the monitors and data panel. If the brightness level of the scene is outside the exposure control range of the camera, the shutter-speed and aperture displays turn red on the monitors and blink on the data panel.
PROGRAM SHIFT - Ps/Pa
Program-shift function allows adjustment to the shutter-speed/aperture combination determined by the camera. The built-in flash cannot be used with program shift. The camera gives priority to the flash exposure; once the flash is raised, any changes made with program shift will be canceled.
As described in the basic recording operation (p. 33), press the shutter-release button partway down until the shutter speed and aperture value are displayed.
Turn either the front or rear control dial to shift the shutter speed and aper- ture combination; each combination gives the equivalent exposure. The val- ues are shifted in 0.3Ev or 1/3 stop increments. The front dial changes the shutter speed (Ps) and the rear dial changes the aperture (Pa). If the lighting changes, the shifted value remains fixed and the other display changes to compensate for the required exposure.
