BULB
You can shoot a trailing image of the movement of a subject with long exposure.
BULB is suitable for shooting trails of light, such as fireworks.
1. Set the mode dial to M (Manual Exposure).
2. Turn the rear dial clockwise until [BULB] is indicated.
3. Select the aperture value (F value) using the front dial.
4. Press the shutter button halfway down to adjust the focus.
5. Press and hold the shutter button for the duration of the shooting.
As long as the shutter button is pressed, the shutter remains open.
Note
Since the shutter speed becomes slow and the camera-shake tends to occur more easily, it is
recommended that you use a tripod.
The longer the exposure time, the more noise will be visible on the image.
After shooting, noise reduction will be done for the same amount of time that the shutter was open.
However, you cannot shoot any more while noise reduction is in progress.
You cannot set the shutter speed to [BULB] in the following situations:
[Cont. Priority AE]
When the [Smile Shutter] function is activated.
When the [Auto HDR] function is activated.
When [Picture Effect] is set to [HDR Painting] or [Rich-tone Mono.].
When the [Multi Frame NR] function is activated.
When the [Drive Mode] function is set to [Cont. Shooting], [Cont. Bracket], [Self-timer(Cont)].
If you use the above functions when the shutter speed is set to [BULB], the shutter speed is
temporarily set to 30 seconds.
Hint
Images shot in [BULB] mode tend to be blurry. We recommend that you use a tripod or a remote
commander (sold separately) that has a shutter button lock function.
