Seagull SYK-4 optical slave trigger with built-in tripod socket is designed to work with portable flash units that have standard hot shoe mount. It can be triggered either by slave sensor or by using PC connector. It also can be mounted either on hot shoe or standard 1/4"- 20 thread tripod screw. This trigger can also be used as a PC to hot shoe adapter by mounting the trigger on a non-hot shoe camera.



  • This optical slave sensor is used to trigger flash unit without slave sensor
  • Can be also used as PC connector to standard hot shoe adapter
  • Work with most flash guns in auto mode or manual mode (TTL mode is not supported)
  • Not compatible with Minolta or Sony flashes as they use different hot shoe connection
