Just received my StudioHut (actually JJC) TM-K intervalometer from Amazon today.

If you're looking for an intervalometer/timer for the Fuji X-E1 this one works. It uses the USB RR80 connector and provides delay/bulb/interval and count functions.

Set the X-E1 to bulb and you can shoot exposures as long as you want. Star trail night photography here we come ...

Only a couple of niggles with it: (1) the lamp turns off too quickly & (2) it doesn't have any memory so when you power it off everything resets. Not a big deal compared to say the cost of the Nikon MC-36.
