Interesting. I was quite worried it was a hotshoe issue, but I've racked up about 900 studio exposures with two different strobes and two different Radiopopper receivers without a single misfire. My best guess is that the power output on the hotshoe is not enough for the Yongnuo, because they work fine with a Canon body. I don't know the difference between the Canon and Nikon versions of the Yongnuo. Since they're just tripping the strobe and not doing any TTL work, I'd assume they're only getting a signal from the middle, largest contact on the hotshoe. But it's possible that the pin pattern on the 603C is just something the Fuji doesn't like. I usually have about a 1-2% misfire rate with the Yongnuos on the Canon. None at all so far with the Radiopoppers.

I took a gamble and got some Radiopopper Nanos. Initial testing with the X-Pro2 is good. Fires the studio strobes as well as speedlites. So I guess the Fuji just didn't like the Yongnuo 603Cs.

Certainly sounds like some kind of delay. I'm having issues with the Yongnuo 603C's not being tripped at all, so I'm wondering if it's something to do with the amount of power being sent to the hotshoe. Maybe it's lower than with other cameras, which would cause a failure to trip, as well as a delay in your PocketWizards. Unfortunately, doesn't seem like very many people are using triggers in the studio with the X-Pro2! Or if they are, they aren't talking about it.

Are you using the V6? Seems to be a bit pricey at $106 on Amazon. [Apparently only $70 at B&H] The PocketWizard Plus X two pack is $170.

Thanks much for the replies. I'll look into the Cactus. My concern is that there may be an issue with the hotshoe. I know the triggers I have work on the Canon. They just don't work on the X-Pro2. Which leads to the question "why." Could be that the power from the X-Pro2 hotshoe is less than what the Yongnuo needs, or it could be the post arrangement, or it could be . . . . etc. I hate to buy new triggers without knowing, but it's looking like that's what I'll have to do to narrow down the cause. --J

My studio work involves simple lighting setups—usually no more than two lights. For a couple of years I've been using Yongnuo RF-603C triggers (one on the camera, and the other on the Einstein). I usually use a Canon DSLR in the studio. This setup has worked fine. I'd like to try transitioning to the X-Pro2 in the studio, but my first efforts ran into a major snag: the X-Pro2 hotshoe isn't sending a signal to the trigger. (Camera set to sync speed, and I ran through all the flash options in the Menu, etc.) This appears to be a communications issue with the Yongnuo, because if I attached a speedlight to the X-Pro2, the speedlight will fire. (Likewise, if I run a PC cable from the socket on the X-Pro2 to the strobe it will fire. If I run a PC cable from the camera socket to the Yongnuo, tripping the shutter doesn't signal the Yongnuo.) I'm wondering if anyone else has encountered this issue. Alternatively, I'd be interested in knowing what radio triggers are being used successfully with the X-Pro2. Thanks!
