Shutter Priority AE

Set the desired shutter speed and the camera selects the optimum aperture accordingly. Use the Tv mode to maintain specific control over action, i.e. shooting sporting events or deliberately blurring your subject.

1.Turn the exposure mode setting dial and set it to "Tv" (shutter 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 shutter speed.

The shutter speed value is adjusted in 1/2 stop increments.

*The aperture 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 shutter speed value by turning the front or rear dial until the aperture value stops flashing and remains lit.

Manual Mode (M)

Use the manual mode "M" when you desire to have complete control over shutter speed and aperture settings. This mode is also best utilized in combination with an independent hand-held exposure meter.

1.Turn the exposure mode setting dial and set it to "M" (manual mode).

*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 rear dial to set the desired aperture. The aperture value is adjusted in 1/2 stop increments.

3.Turn the front dial to set the desired shutter speed.

The shutter speed value is adjusted in 1/2 stop increments.

4.When the shutter release button is half- pressed, the difference between the manual settings and the metered value is displayed in the viewfinder's LCD panel. The value is displayed in 1/3 stop increments within a range of ± 6 EV.

*For example, "+2.3" indicates +21/3EV, "-5.7" indicates -5 2/3 EV.

*If the manual settings and the metered value are the same, nothing is displayed as a difference in the viewfinder's LCD panel.
