The NRD Firefly introduces yet another way to get rid of dust from DSLR image sensors. Itâ€™s a touch-less dust removal system, there is no physical contact between the surface being cleaned and the cleaning device. NRDâ€™s Greg Gumkowski says the Firefly takes care of the dust very quickly and very simply without danger of damaging the sensor.
It looks like an air blower on steroids; it has a 9-volt electronic gadget that multiplies the batteryâ€™s voltage to a point where corona discharge will occur. The air ions are blown into the sensor â€“ which attracted the dust in the first place because of its electrostatic charges â€“ and the dust specks are supposed to just lose their stickiness and fall off.
And thatâ€™s how itâ€™s supposed to work. The NRD Firefly blows ions into the sensor and the dust will just fall off. My question is, whereâ€™d they go, they fall off where?
