Sony A580 Anti-Dust Technology
To help combat dust particles on the sensor from changing lenses, Sony included both an anti-static coating on the sensor filter and anti-dust vibrations to automatically shake the sensor with the anti-shake mechanism each time the camera is shut off. There is also a manual cleaning mode, where the camera first shakes the sensor, then lifts the mirror and opens the shutter, allowing access to the sensor for use with a blower or other cleaning device.
