Auto Info Display
If this is turned On, the Information Display will automatically appear on the Monitor when the
Shutter-Release Button is pressed half-way and after shooting if image review is turned off.
Turn this Off to conserve battery life, unless you are often referring to this screen and don't wish
to have to press the INFO Button or i Button each time.
Clean Image Sensor
Leave this set at Cleanup at startup/shutdown so that the automatic sensor cleaning happens
every time you turn your camera on or off. You can interrupt it when you turn the camera on by
tapping the Shutter-Release Button. Since the sensor cleaning works by vibrating the low-pass
filter in front of the sensor, it is recommended to hold or set the camera level and in the standard
orientation as this happens. You can also use this menu item to perform this automatic sensor
cleaning process at any other time. See below for manual Sensor Cleaning.
Lock Mirror for Cleaning
This is to lock up the mirror so that you can manually clean the sensor. See the Sensor Cleaning
section of the text for more information.
