The X100/s (as well as the entire Fuji lineup) can shoot with on-board flash till 1/4000th of a second, which is great for shooting wide open in the mid-day sun, leaving the background dark while having your subject lit with a speedlight. Does anyone have any advice on using off camera radio triggers (or IR triggers for that matter) which will allow an off-camera flash unit to be used with fast shutter speeds? . What are decent radio triggers that work well with the Fuji line-up? . How fast can one shoot? As an example, I tried shooting the Ricoh GR with a single Elinchrom D-Lite 4 (studio light on a battery pack) in the mid-day sun, at 1/1000th of second (that's the fastest I could go with the GR and that particular light). Here's the image (right click and open in new tab to see large) - Any help/advice would be much appreciated. Thanks.
