a: Manual Exposure
110
To obtain a correct flash exposure, the flash output will be set 
automatically (autoflash exposure) to match the manually-set aperture. 
The shutter speed can be set from 1/200 sec. to 30 sec or bulb.
A bulb exposure keeps the shutter open 
for as long as you hold down the shutter 
button. It can be used to shoot fireworks 
and other subjects requiring long 
exposures.
In step 3 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.

BULB: Bulb Exposures
Elapsed exposure time
 
During the bulb exposure, do not point the camera toward an intense 
light source, such as the sun on a sunny day or an intense artificial light 
source. Doing so may damage the image sensor or the camera’s internal 
components.
 
Since bulb exposures produce more noise than usual, the image may 
look slightly grainy.
 
You can reduce the noise due to long exposures by setting [4: Long exp. 
noise reduction
] under [53: Custom Functions (C.Fn)] to [1: Auto] or 
[2: On] (p.260).
 
If ISO Auto is set for a bulb exposure, the ISO speed will be fixed at ISO 
800 (p.90).
For bulb exposures, using a tripod and a remote switch (sold separately, 
p.269) is recommended.
