Long (Bulb) Exposures

In this mode, the shutter stays open as long as you hold down the shutter button completely, and closes when you let go of the shutter button. Use bulb exposures for night scenes, fireworks, astrophotography, and other subjects requiring long exposures.

  1. Set the Mode dial to M.

  2. Set the shutter speed to [BULB].

    • Turn the Dial dial to the left to set [BULB].
  3. Set the desired aperture value.

    • Press the Up key key to select the aperture value, then turn the Dial dial to set a value.
  4. Take the picture.

    • The exposure will continue for as long as you keep the shutter button pressed completely.
    • Elapsed exposure time is shown on the screen.


  • Do not point the camera toward an intense light source, such as the sun or an intense artificial light source. Doing so may damage the image sensor or the camera's internal components.
  • Long bulb exposures produce more noise in the image than usual.
  • ISO 400 is used when the camera is set to ISO Auto.


  • You can reduce the noise generated during long exposures by using [Shooting: Long exp. noise reduction] ().
  • Using a tripod is recommended for bulb exposures.
  • You can also shoot bulb exposures by using Wireless Remote Control BR-E1 (sold separately, ). When you press the remote controller's release (transmit) button, the bulb exposure will start immediately or 2 sec. later. Press the button again to stop the bulb exposure.
