Fuji X-T2 + Canon 580EX issue
Hi all,
Newbie to this group. I've been using PocketWizard FlexTT5(s) on Canon 5dII for at least 2 years and PWs have always been reliable, rarely miss any shot. Since moving to Fuji-X system, I've been looking for an alternative to ETTL+HSS and finally after reading many positive users comments, decide to get Cactus V6II. It took me a while to read through manual/blog and after several "Learn HSS" tries, it finally works.
However, the problem I have is with the trigger's consistency. Even with both flash & camera are next to each other (not about the radio range), there are so many trigger misses. Sometimes, 4-5 in a row and hit twice then miss again. The overall "hit" rate is very low ~30-40%, very frustrated. I only shoot in "single" shot mode, ensure flash power is already ready before the shot. Battery is fresh in both flash + triggers.
Here is my setup:
- Fuji X-T2 w/ hot shoe metal spring removed. (For my XT2, hot shoe does not seem a problem)
- Canon 580EX on ETTL + HSS
- Flash power: 1/32s -> 1/64s
- Exposure: 1/1000s, f/4
For Cactus:
- FW 1.006
- Camera system: Fujifilm
- Flash profile: Canon 580EX
- Force HSS ON
- Normal HSS
According to Lilo, he reported a higher rate, 75%. That's at least reasonable but not what I get. If I could not figure out soon, I would have to give it up.
Any help would be appreciated.

Comments
If the transmitter is within close proximity of receivers, the latter can experience radio signal overload. Changing the range setting to "SHORT" fixes that and will still leave you with a very comfortable work range. Unless you go outdoors and try to attempt some long distance triggering, "SHORT" should do just fine.
I always set my transmitter to "SHORT" and have never needed to change it back to "LONG".
What shutter speeds were you shooting at when it missed. More precisely, were you adjusting the shutter speeds above and then below X-sync speed?
Did you manually turn on Forced HSS when shooting above x-sync, and vice versa?
Does it makes a difference if you let the V6 II RX auto-detect the flash? And not manually choosing 580EX*?
Thank you.

It definitely has nothing to do with indoor vs outdoor, but the the rather jumpy timing on Fujifilm cameras.
What
that means is, when you execute LEARN HSS on the V6 II (TX) capturing
the shutter timing this moment may not be the actual (usual) time the
camera uses. So when you take the shot in HSS mode, it could be a miss.
Until
we resolve the HSS issue completely after studying the EF-X500, you
will need to continue using Learn HSS +manually turning Forced HSS off
and on. For older camera models, such as the X-Pro1, people will need
to continue using Learn + Forced HSS, unless Fujifilm releases a new
camera firmware.
So for now, you simply need to redo LEARN HSS. Test if you are able to consistenly fire and sync the flash.
That said, we estimate a full Fujifilm firmware be ready on the V6 II in Q1 2017.
Thank you and we appreciate your patience in the meantime.
