The Lastolite Sync Block for Remote Triggers is an ingenious method to enable a portable flash without a sync socket to be used with a radio remote system (radio remote controls not included). To use your radio remote control, attach the cast aluminum Sync Block to the bottom of your flash and plug the sync cord that's connected to the Sync Block into your radio receiver unit. Your portable flash can now be fired using your radio remote transmitter. The flash may be used in non-TTL modes only. The Sync Block is compatible with any radio trigger featuring a PC sync/X sync socket.
