I had previously been the transmitter of Yongnuo RF-603CII and two YN560-III Speedlite (manual flashes) in use with my Fuji X system. Had lacked the possibility of wireless flashing with the system set me the possibility that lightning also via radio. This is possible with the YN560-TX now finally in Yongnuo system. Price is unbeatable when compared with the established systems such Phottix PocketWizard or so I have only once set no great expectations in the system. Now he has finally been delivered and of course I have to get started right away: Packaging is fine, description in English of course and easily. There are three groups are driven, I assigned my flashes A and B, and both can be perfect in terms of performance, zoom and flash mode (M / Multi) separately adjust quickly. No run to softbox and more fumble behind the diffuser but convenient wireless set from the camera. PERFECT !! Reach I could not test, but if anywhere near as much as the RF-603CII then I'm satisfied. with 603CII the YN560-TX course also works in both directions, that is, the wireless remote flash of the camera is via the built-shutter release socket (at the Fuji X-E1 and the X-T1, not at the X-Pro1) without any problems.
