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.
During bulb shooting, images tend to blur. It is recommended that you use a tripod, a Bluetooth remote commander (sold
separately) or a remote commander equipped with a lock function (sold separately). When using the Bluetooth remote
commander, you can start bulb shooting by pressing the shutter button on the remote commander. To stop bulb shooting, press
the shutter button on the remote commander again. To use the other remote commander, use the model which can be connected
via the Multi/Micro USB terminal.
Note
The longer the exposure time, the more noise will be visible on the image.
