Bulb shooting
You can shoot a trailing image of the movement of a subject with long exposure.
Bulb shooting is suitable for shooting trails from stars or fireworks, etc.
Hint
When shooting fireworks, etc., focus at infinity in manual focus mode. If you use a lens whose infinity point is unclear, adjust the
focus on the fireworks in the area you want to focus on in advance.
In order to perform bulb shooting without causing the image quality to deteriorate, we recommend that you start shooting while
the camera is cool.
Images shot in [BULB] mode tend to be blurry. We recommend that you use a tripod and a remote commander (sold separately)
that has a shutter button lock function. Use a remote commander supporting connection via multi/micro USB jack.
Note
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:
[Auto HDR]
[Picture Effect] is set to [Rich-tone Mono.].
When [Drive Mode] is set to the following:
[Cont. Shooting]
[Self-timer(Cont)]
[Cont. Bracket]
[
Silent Shooting]
If you use the above functions when the shutter speed is set to [BULB], the shutter speed is temporarily set to 30 seconds.
