How do I clean the EOS 5D Mark II sensor.


Whenever you set the power switch to <ON/> or <OFF>, the Self Cleaning Sensor Unit operates to automatically shake off the dust on the front of the sensor. Normally, you need not be aware of this operation. However, you can execute the sensor cleaning at anytime as well as disable it.

1. Turn the camera's power switch to < > (Quick Control Dial).

2. Press the <MENU> button to bring up the menu.

3.Turn the <Main Dial> to select the [ ] tab.

4. Select the Sensor Cleaning settings.

4-1. Turn the <Quick Control Dial> to select [Sensor cleaning].

4-2. Press the <SET> button and turn the <Quick Control Dial> to select [Clean now] from the menu that appears, and then press the <SET> button again.

5. Turn the <Quick Control Dial> to select [OK] from the screen that appears, then press <SET> button.

The screen will indicate that the sensor is being cleaned. Although there will be a shutter sound, a picture is not taken


  • For best results, do the sensor cleaning while the camera bottom is placed on a table or other surface at a perpendicular angle.
  • Even if you repeat the sensor cleaning, the result will not improve that much. Right after the sensor cleaning is finished, the [Clean now] option will remain disabled temporarily.

6. Press the <MENU> button and turn off the display on the LCD monitor.

This completes the process of cleaning the sensor immediately.
