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 that has collected.

1

Select [Dust Removal] in the [R Set-up 3] 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 [Start-up Action] and [Shut-down 

Action] to O.
When Dust Removal is completed, the camera returns to the [R Set-up 3] 

menu.

Removing Dust by Shaking the CMOS Sensor 

(Dust Removal)

Use a brush-less blower to remove dirt and dust from the CMOS sensor. Using 

a blower with a brush may scratch the CMOS sensor. Do not wipe the CMOS 

sensor with a cloth.
