After doing some research, I could not find a lot of definitive answers regarding radio triggers for the Fuji X100s. What I am envisioning is using a radio trigger mounted on the X100s, and syncing with a flash (Yongnuo YN-560 III). I understand that radio triggers may not allow to sync faster than of 1/500s, however, some users indicate some success up to 1/2000s. Anyone using this set up with their X100s? I don't want to use a cord or optical trigger if I don't need to. The cord can be somewhat flimsy and is limited by length, and the optical can be iffy outdoors or in certain setups. Any help is appreciated.
