Synchronizing the Camera Time

You can synchronize the time for multiple EOS-1D X Mark III units with WFT-E9 attached.

The camera that sets the time to synchronize is called the "sender camera," and the camera that synchronizes with the time of the sender camera is called the "receiver camera."

Up to 10 receiver cameras can be synchronized.


  • Make sure to perform time synchronization on cameras of the same model. If the sender camera and receiver camera models are different, time synchronization on the receiver camera will not work.
  • Note that even after synchronization, there will be a margin of error (plus or minus 0.05 seconds) between sender and receiver camera times.
