P/A Controlling Exposure: Exposure Modes
In P and A modes, shutter speed and aperture can be
adjusted to suit the user’s creative intent.
P and A modes also give the user control over ISO sen-
sitivity (c50), white balance (c52), and the options in
the Shooting menu (c86).
P: Programmed Auto
mode, different combinations of shutter speed
and aperture can be selected by pressing the multi
selector right (“flexible program”). Press the multi
selector right or left to switch from one to the other.
While flexible program is in effect, shutter speed and
aperture are displayed yellow (otherwise, they are
displayed white), and an asterisk (“*”) appears next
to the exposure mode indicator in the shooting dis-
play. To deactivate flexible program, press the multi
selector left or right until the shutter speed and aperture are displayed in white, or rotate the
mode dial to a different setting. Turning off the camera also deactivates flexible program.
