The MicroSync PC Male to Sub-Miniphone Sync Cord features a sub-mini plug at one end, and a male PC (post connection) plug at the other end. This allows the MicroSync Receiver to be connected to the Canon 580EX II or Nikon SB-26, SB-28, SB-80, SB-800, and SB-900 flashes for remote triggering. Can also be used with lightmeters, which usually use a PC male cord.
