Dust particles almost inevitably accumulate on the sensor the longer the camera is in use. With the Arctic Butterfly SL 707 sensor brush, these can be removed easily, efficiently, and most importantly, permanently. The brush features exceptionally fine polymer fibers with high dust retention capacity and a battery-operated motor that statically charges the fibers through rotation, further enhancing their ability to capture dust. The AB SL 707 is suitable for dry dirt particles of almost any kind. As the smallest member of the Arctic Butterfly family, it fits in nearly any camera bag and is always on hand.
