Programmed automatic exposure
For fast, fully automatic photography. In this mode, exposure is controlled by automatic setting of shutter speed and aperture.
To set this mode, turn both dials to their A positions.
• The mode is indicated by P (2.1.1).
To take a picture with this mode
1.Press the shutter release button (1.8) to its pressure point.
•The shutter speed (2.1.17) and aperture (2.1.20) appear in white.
In addition, the indication of the possibility to use the program shift func-
tion also appears 
(2.1.15, see next section).
If even the fully opened or closed aperture in conjunction with the slow- est or fastest shutter speed would result in under- or overexposure, both values turn red as an indication.
If the automatically set pair of values seems appropriate for the intended com- position:
2. Press the shutter release button all the way down to take the photograph.
If not, you can change the pair of values before pressing the shutter release button:
Shifting program mode
Shifting the program mode curve combines the reliability and speed of fully automatic exposure control with the possibility of being able at any time to vary the speed/aperture combination selected by the camera according to your ideas.
This is done with the setting ring (1.22). For example, if you are taking sports photographs and prefer to use fast speeds, turn it to the left (anticlockwise). If, on the other hand, you would rather have a large depth of field (small aperture) and accept the associated slower speeds that are necessary, then turn it to the right (clockwise) (e.g. for landscape photography).
The overall exposure, i.e. the brightness of the image, remains unchanged. The shift range is limited in order to keep a correct exposure.
•Whenever a value pair is changed by shifting, there are two indications, an asterisk next to the values (2.1.16) and a symbol representing the setting ring (2.1.15). This allows the automatic default pair of values can be recog- nized at any time.
•When exposure metering is switched off automatically after 12s, the pro- gram shift is defaulted, i.e. reset to the values suggested by the camera.
•Program shift is also defaulted after taking a picture, thus preventing ac- cidental use.
