Sony α SLT-A58 Instruction Manual page 195

• If you use a Remote Commander* that is equipped with a shutter button
lock function (sold separately), you can keep the shutter open using the
Remote Commander.
* Use a Remote Commander that is compatible with a Multi/Micro USB
Terminal.
Notes
• When using a tripod, turn off the SteadyShot function (page 84).
• The longer the exposure time, the more conspicuous the noise on the image.
• After shooting, noise reduction (Long Exposure NR) will be performed for the same
amount of time that the shutter was open. You cannot do any further shooting during
the reduction.
• When the Smile Shutter or Auto HDR function is activated, or when [Picture Effect]
is set to [HDR Painting] or [Rich-tone Mono.], you cannot set the shutter speed to
[BULB].
• If the Smile Shutter, Auto HDR function, or the [HDR Painting] or [Rich-tone
Mono.] setting of [Picture Effect] is used with the shutter speed set to [BULB], the
shutter speed is temporarily set to 30 seconds.
• We recommend that you start BULB shooting while the temperature of the camera is
moderate to prevent the quality of the image from deteriorating.
