P
: Programmed Auto
In this mode, the camera automatically adjusts shutter speed 
and aperture according to a built-in program to ensure optimal 
exposure in most situations.
A
Flexible Program
In exposure mode P, different combinations 
of shutter speed and aperture can be 
selected by rotating the main command dial 
while the exposure meters are on (“flexible 
program”). All combinations produce the 
same exposure. While flexible program is in 
effect, an asterisk (“
U”) appears in the control 
panel. To restore default shutter speed and 
aperture settings, rotate the dial until the 
asterisk is no longer displayed, choose another mode, or turn the 
camera off.
