Black bar on photo?

Had another shoot today, was using 1/160 and had this occur 3 times in ~900 shots. So it's still there, probably just have to admit that the Yongnuos are almost reliable but not 100%.

Just to add another data point; I used to encounter the same issue with my Yongnuo 602 triggers with a similar regularity - i.e. every few hundred images I might see the shutter in a shot. Just one of those things.

And FWIW, in the studio I've been working in where we use Broncolor Scoro packs triggered by their RFS Transmitter, we have to run the Canon cameras at 1/3 - 2/3 slower than their stated max flash sync speed to avoid regular issues like this as well.

For $40 per transceiver, I'd say that's pretty good. I also suspect that no radio trigger system is 100%.

For what it's worth, I had more issues with a PC sync cord misfiring than I've had with my YN622's.
