the "anti-dust sensor" isn't for dust on the sensor... misconception...
the "cleaning device" for the sensor is just layman terms for removing any excess charge that is still trapped in the cmos censor... these charges are the information for the pixels... by removing the charge, this prevents charge buildup on the fets... so when you turn on your camera, the cmos sensor is in a neutral state...
the cleaner removes excess charge... in a sense you can call it a dust cleaner, because if there's no charge on the sensor, then the dust won't adhere to that sensor... but its not really a dust cleaner... and now i find myself talking around in an endless cycle that never ends.... engineers shouldn't be allowed to explain things
