BULB: Long (Bulb) Exposures
You can preset the bulb exposure’s exposure time. With the bulb timer,
you need not keep holding down the shutter button during the bulb
exposure. This reduces camera shake.
The bulb timer can be set only for <BULB> (bulb exposure). It cannot
be set (or will not function) in any other mode.
