3.7Exposure Modes

(P) Program AE

The aperture and shutter speed are determined automatically for the optimum exposure, according to the existing ambient light. This mode

If the shutter speed and aperture values blink on the main LCD and in the viewfinder display when the program line is shifted, the proper exposure cannot be achieved.

Please select a different Program mode.

When the Program line is shifted, the aperture value changes along with the shutter speed to maintain the proper exposure.

You can choose either aperture or shutter-speed to give priority in program line shift. Custom settings C-14.

Increment of the aperture and shutter speed can be set at either 1/3 or 1/2- stop. Custom settings C-01.

is best suited for general photography, allowing the user freedom to concentrate on the subject.

Hold down the [program] button and turn the exposure mode setting dial to “P” (program AE) position.

Program Shift (PH/PL)

You can change the shutter speed and aperture value by turning the front and rear dials in the “P” (Program AE) mode. In order to avoid blurred images (due to shaking while releasing the shutter), or to open the aperture, change to “PH” (high speed). For slower shutter speeds and wider depth of field, change to “PL” (low speed). This function allows you to make these changes quickly.
