With the Pixel Pawn trigger set you can control remote flash units. You can use this set to wirelessly control your studio flash. The connection between the transmitter and the camera and the receiver with the lamp is via a supplied synchronization cable. If you want to use the set for strobist, it is important to know that you can only control the following external camera flashes: SB-910, SB-900, SB-800, SB-700, SB-600 and SB-400 . Use with other flash units is not recommended because the flash synchronization will not work, for example.
