Mirror Lockup

You can use the mirror lockup function to prevent the disturbing mechanical vibrations (mirror shock) when shooting with super telephoto lenses or shooting close-ups (macro photography).

  1. Configure the mirror lockup setting.

    • Set [10: Mirror lockup] in [Set-up: Custom Functions(C.Fn)] to [1:Enable] ().
  2. Focus on the subject, then press the shutter button completely.

    • The mirror will swing up.
  3. Press the shutter button completely again.

    • The picture is taken and the mirror goes back down.
    • After taking the picture, set [Mirror lockup] to [0:Disable].

Tips Shooting tips

  • Also set the self-timer to [10 sec. self-timer] or [2 sec. self-timer].

    When you press the shutter button completely, the mirror locks up. The picture will be then taken 10 sec. or 2 sec. later.

  • Shoot remotely.

    Since you do not touch the camera when the picture is taken, remote control shooting together with mirror lockup can further reduce the camera vibration blur ().

    With Wireless Remote Control BR-E1 (sold separately) set to the 2 sec. delay, press the release button to lock up the mirror, and the picture will be taken 2 sec. after the mirror lockup.

    With Remote Switch RS-60E3 (sold separately), press the release button completely to lock up the mirror, and press it completely again to take the picture.


  • 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.
  • In very bright light, such as at the beach or a ski slope on a sunny day, take the picture promptly after mirror lockup is stabilized.
  • When shooting with mirror lockup, if you use both the self-timer and bulb exposures, keep pressing the shutter button completely (for self-timer delay time + bulb exposure time). No shot will be taken if you release the shutter button during self-timer countdown, although a shutter-release sound will be played.
  • During mirror lockup, shooting function settings, menu operations, etc. are disabled.
  • When you use flash, the red-eye reduction lamp will not light up.


  • Even if you set the drive mode to [High-speed continuous shooting], [Continuous shooting], or [Self-timer: Continuous], the camera will still shoot in the single shooting mode.
  • When [Shooting: High ISO speed NR] is set to [Multi Shot Noise Reduction], four consecutive shots will be taken for a single picture regardless of the [Mirror lockup] setting.
  • If approx. 30 sec. elapse after the mirror has locked up, it will go back down automatically. Pressing the shutter button completely locks up the mirror again.
  • When shooting with mirror lockup, using a tripod and Wireless Remote Control BR-E1 (sold separately, ) or Remote Switch RS-60E3 (sold separately, ) is recommended.
