P Program mode
The camera automatically adjusts shutter speed and aperture value so
that an optimal exposure value can be achieved.
This mode is useful when you want to capture shots of constant
exposure while being able to adjust other settings.
Program Shift
Program Shift function lets you adjust the shutter speed and aperture
value while the camera maintains the same exposure. When you scroll
the jog dial to the left or rotate the navigation button counter-clockwise,
the shutter speed decreases and the aperture value increases. When
you scroll the jog dial to the right or rotate the navigation button
clockwise, the shutter speed increases and the aperture value
decreases.
