Sold with free shipping. The Visible Dust FlexoDome (Canon DSLR Cameras) features a ring to be attached to each specific camera body for hands-free operation. The cup on FlexoDome is uniquely designed to accept a variety of nozzles from different bulb blowers. Once attached to the camera body, FlexoDome acts as a fence against the sensor contact and blower nozzle allowing the operator to invert the camera's sensor downward without the fear of entering the chamber area damaging the sensor. This method facilitates the removal of heavier particles based on gravity action. However, this seems to be impossible task when camera's sensor is faced upward acting against the gravity. By using FlexoDome one can remove all dust particles regardless of their size.
