Pair your select Canon camera to the Case Relay System with this Relay Camera Coupler from Tether Tools. In this case, it takes the place of the LP-E5-type battery pack and provides a connection to the power source for long-term, continuous operation of your camera. This setup can easily be swapped out with another coupler to provide you with compatibility across camera systems.
