Selecting the shooting mode
• Use the Wireless Remote Commander (sold separately) (page 148).
Pressing the SHUTTER button on the Wireless Remote Commander
triggers BULB shooting and pressing it again stops BULB shooting. You
do not need to press and hold the SHUTTER button on the Wireless
Remote Commander.
• If you use a Remote Commander that is equipped with a shutter button
lock function (sold separately), you can leave the shutter open using the
Remote Commander.
Notes
• When using a tripod, turn off the SteadyShot function (page 87).
• The longer the exposure time, the more conspicuous the noise on the image.
• After shooting, noise reduction (Long Exposure NR) will be done 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.
• It is recommended that you start BULB shooting after the temperature of the camera
drops to prevent the quality of the image from deteriorating.
