The Low-Pass Filter

The image sensor that acts as the camera’s picture element is fitted with a low-pass filter to prevent moiré. If you suspect that dirt or dust on the filter is appearing in photographs, you can clean the filter using the Clean image sensor option in the setup menu. The filter can be cleaned at any time using the Clean now option, or cleaning can be performed automatically when the camera is turned on or off.
