This cable was primarily designed as an interface between your camera and StopShot for high speed triggering of your camera but it will also work with StackShot. It is extremely useful for keeping shutter lag to a minimum for Canon users and it will allow StopShot to wake up your camera from sleep mode. It also gives a method of quickly disconnecting and connecting StopShot from your camera, very useful for setting up sensors.
