The harm the dust does to your digital camera
When the there is some dust on the surface of lens, some part of the photo will look soften. And your mode will be affected. The battery touch spot and press key are most affected by the dust. What’s worse, it may lead bad contact and keypad failure. If the transducer is caught by the dust, dark space will be showed on the picture directly.

The lens should not be directly touched. If the there is some dust on the lens, it’s better to blow. For some oil dust which can’t be blow away, 3M ScotchBrite can be effective. But the scotchbrite should be new and clean. For the dust on the camera body, brush can be used. Only take care no sweeping to the parts which is sensitive to dust."
