About [B] (Bulb)
∫
If you set the shutter speed to [B], the shutter stays open while the shutter button is
pressed fully (up to approximately 120 seconds).
The shutter closes if you release the shutter button.
Use this when you want to keep the shutter open for a long time to take pictures of
fireworks, a night scene etc.
• It can only be used with Manual Exposure Mode.
• We recommend using a tripod or the shutter remote control (DMW-RSL1: optional)
when you take pictures with the shutter speed set to [B].
Refer to P315
• When you take pictures with the shutter speed set to [B], noise may become visible. To
avoid picture noise, we recommend setting [Long Shtr NR] in the [Rec] menu to [ON]
before taking pictures.
