Program AE (P)

The aperture and shutter speed are determined automatically for the optimum exposure, according to the existing ambient light. This mode is best suited for general photography, allowing the user freedom to concentrate on the subject.

Turn the exposure mode setting dial and set it to "P" (program AE).

*In the "X" exposure mode the lock function is activated. Press the exposure mode dial lock release button while turning the exposure mode setting dial.

Shifting the Program

Use "PL” to record subjects with depth using a smaller aperture (landscapes, etc.), "PH" to record moving subjects with a high shutter speed.

Turn the front or rear dial to shift the shutter speed between the +1.0 EV high speed side "PH" and -1.0 EV low speed side "PL".

PL =Program Low / slower (low) shutter speeds

PH= Program High / faster (high) shutter speeds

*If the aperture flashes on the main LCD and in the viewfinder display when the program is shifted, the proper exposure cannot be achieved. Please select a different Program mode.

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

Aperture Priority AE

Set the desired aperture and the camera selects the optimum shutter speed accordingly. Use the Av mode to maintain specific control over depth of field, i.e. taking portraits or landscapes.

1.Turn the exposure mode setting dial and set it to "Av" (aperture priority AE).

*In the "X" exposure mode the lock function is activated. Press the exposure mode dial lock release button while turning the exposure mode setting dial.

2.Turn the front or rear dial to set the desired aperture.

The aperture value is adjusted in 1/2 stop increments.

*The shutter speed value on the main LCD and in the viewfinder display will flash when photographing objects that are too bright or too dark for proper exposure. The proper exposure cannot be achieved at the present settings. Change the aperture value by turning the front or rear dial until the shutter speed value stops flashing and remains lit.
