Delivery OK, build quality given the price amazingly well! The transceiver also now have a Befestigungsrad and the on / off switch is at the side or the release button can now be still operate even with an attached flash. Reach I could not test, however, by two walls the stations still operate properly. The Fuji X-cameras up to 1 / 200s are flashed at 1 / 250s it comes to shadowing by the curtain. Unlike its predecessors, this need not be modified for use in the X-Pro1, both the display, EVF and OVF use function the connected lightning perfectly. Note: it may be naturally flashed manually with these transceivers. The remote trigger function works on the X-E1 with the supplied cable also wonderful (incl. Focus since two-stage trigger) All in all, at the price perfect!
