Wein Optical Slaves are the classic solution for wirelessly syncing virtually any amount of flashes to your camera. Wein Optical slaves will fire in sync with the first white light or infrared pulse that it detects. If your "key" flash emits a pre-flash Wein recommends using: the camera in manual mode so that no pre-flashes are emitted.
