Sony ILCA-99M2 - Manual (Page 111)

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.
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]
If you use the above functions when the shutter speed is set to [BULB], the shutter speed is
temporarily set to 30 seconds.
