When dust begins its attack on your camera’s sensor, you will have to pay the price in post-processing to take away every single black spot in your otherwise awesome images. Firefly wants to help you with that using their new generation battery powered air blower that shoots ionized air into your camera body to clean it out.
Simply install a 9-volt battery into the Firefly which allows it to produce both positive and negative charged air ions which will neutralize the static charge in your camera. Without static, the dust simply falls off. No charge. No dust. Happy photographer.
