Press Release:
This is a brief update about RoboSHOOT© flash Triggers for Fuji
What sync speed can you expect with the x100? We’ve frequently gotten this question and the answer is complex enough that it warrants this notice.
We’ve tested on both X100s and X100T and found synch speeds work all the way to 1/4000s. So, yes, RoboSHOOT© supports all shutter speeds on these cameras.
But, there are things to be aware of. Firstly, at higher flash power the flash duration can be longer than 1/1000s. So, you will frequently see brightness fall off starting at 1/1000s, especially if the aperture is stopped down (because more power is requested). Secondly, the longer the flash duration, the more sensitive it is to any delay (there is about 500 microseconds of delay from the radio). Lastly, the camera only requests so much power, so again, stopping down reaches a limit. Thus, these three physical limitations come into play to affect the exposure, and they compound when multiple limitations occur. So, practically, what does this mean?
RoboSHOOT© does supports TTL on the X100 series throughout the shutter speed range: no HSS required. However, at very high speeds (about 1/1000s and above) you may want to keep the aperture wide-open, and regardless, you may see under exposure at extreme speeds. Of course, some of this can be compensated for with flash exposure compensation. So, enjoy experimenting with this fun option!
