Extended Exposure Modes (Bulb and Time Modes)

To expose the film for extended times (over 30 seconds), set the shutter speed to bulb

or set the exposure mode setting dial to "T" (Time Mode).

Bulb Mode

The bulb mode uses electronic control, so the batteries are in constant use during the entire exposure.

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

2.Turn the front dial counterclockwise to select "bulb", then turn the rear dial to set the aperture.

3.Determine the composition, focus, then take the picture. The shutter remains open as long as the shutter release button is pressed.

Time Mode

The time mode uses mechanical control, so it is best suited for extended expo- sures. The batteries are not used to keep the shutter open during the exposure.

1.Turn the exposure mode setting dial and set it to "T" (time mode).

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

3.Press the shutter release button. Determine the composition, focus, then press the shutter release button. The shutter opens.

4.Once you have achieved the desired exposure, turn the exposure mode setting dial to "X". The time exposure mode is canceled and the shutter closes.

*To prevent the camera from moving, use both an electromagnetic cable release (sold separately) and a tripod.

*When the BL (Backlight) button ”A” is pressed, the main LCD panel and the maga- zine LCD panel light for about 10 seconds. This makes the liquid crystal display panels easier to view in dark places, for example when photographing night views.

*In the "X" exposure mode the lock function is activated. To set a different mode, press the exposure mode dial lock release button “B” while turning the exposure mode setting dial.
