3
Press the shutter button halfway down to focus.
4
Press and hold the shutter button for the duration of the shooting.
5
As long as the shutter button is pressed, the shutter remains open.
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 or 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:
[Smile Shutter]
[Auto HDR]
[Picture Effect] is set to [HDR Painting] or [Rich-tone Mono.].
[Multi Frame NR]
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.
