Cleaning the CMOS Sensor

If the CMOS sensor becomes dirty or dusty, shadows may appear in 

the image in certain situations such as when shooting against a white 

background. This indicates that the CMOS sensor must be cleaned.

Shaking the CMOS sensor removes dust from the sensor unit. 

1

Select [Dust Removal] in the [R Set-up 4] menu, and press 

the four-way controller (5). 

The [Dust Removal] screen appears.

2

Press the 4 button. 

The Dust Removal function is activated 

by shaking the CMOS sensor. 
To activate the Dust Removal function 

every time the camera is turned on and 

off, set [Startup Action] and [Shutdown 

Action] to O. 
When Dust Removal is completed, the 

camera returns to the [R Set-up 4] menu.
