a: Manual Exposure
100
To obtain a correct flash exposure, the flash output will be set
automatically (autoflash exposure) to match the manually-set aperture.
The flash sync speed can be set from 1/200 sec. to 30 sec. and bulb.
A bulb exposure keeps the shutter open
for as long as you hold down the shutter
button. It can be used to photograph
fireworks, etc.
In step 2 on the preceding page, turn the
<6> dial to the left to set <BULB>.
The elapsed exposure time will be
displayed on the LCD monitor.
I Using the Built-in Flash
BULB: Bulb Exposures
During the bulb exposure, do not point the lens toward the sun. The
sun’s heat can damage the camera’s internal components.
Since bulb exposures produce more noise than usual, the image might
look a little grainy.
You can reduce the noise due to long exposures by setting [4: Long exp.
noise reduction] to [1: Auto] or [2: On] in the [7 Custom Functions
(C.Fn)] (p.253).
If ISO Auto is set for bulb exposures, the ISO speed will be fixed at ISO
400 (p.80).
For bulb exposures, using a tripod and Remote Switch (sold separately,
p.262) is recommended.
You can also use a remote controller (sold separately, p.261) for bulb
exposures. When you press the remote controller’s transmit button, the
bulb exposure will start immediately or 2 sec. later. Press the button
again to stop the bulb exposure.
