Example A: normal program
A lens with f/2.8 as the largest aperture is used; the shutter speed dial is set at "30" (next to the symbol "P"). In poor light, the camera always works with full aperture and shutter speeds between 16 s and 1/30 s. If the Ev value increases (more available light), the aperture is stopped down and the shutter speed is increased continuously, until the combination f/22 and 1/2000 s is reached (line A). If, for instance, the Ev reads 14, the program mode produces exposure at 1/250 s at
Example B: program for depth of field
If a smaller shutter speed is given, e.g. by setting "2" = 1/2 s the automatic program functions as shown by line B. This is the method of choice for better depth of field and is ideally suited to shorter focal lengths, stationary subjects and good lighting conditions.
Taking the same Ev value of 14, the automatic program now computes 1/60 s at
Example C: program for action shots:
If the shutter speed is set to a shorter exposure time (higher shutter speed) - e.g. "500" = 1/500 s, line C applies. This program "prefers" higher shutter speeds (shorter times), ideal for freezing moving subjects or when using longer focal lengths. Again taking an Ev of 14, the automatic program now computes I/1000s at
