Cactus V6II does not work with the new firmware 2.00 X-Pro2

olliviergirard · October 2016

Hello there,

I updated my X-Pro2 with the new firmware 2.00. It works very fine and the autofocus is so good in any situation. Now, the Cactus V6II does not work with the X-Pro2. Do i need a beta firmware or something else?

Best regards

Ollivier

Yes, you need a beta version of the firmware.

Go to:

http://www.cactus-image.com/community/discussion/1005/fujifilm-x-t2-compatibility-with-cactus-v6-ii-to-support-hss#latest

for more details, you have to send an email to an account and they send to you the beta update and the process. The cactus people sent me the firmware and now I´m using the x-pro2 with firmware 2.0 and HSS.

A couple of examples at 1/1000 and 1/2000 with the x-pro2 FW 2.0

Xpro2 FW - 2.00

Cactus FW - 1.0.108

2 separate flash units - Canon 550EX, Canon 580EXii Both are HSS capable.

-I have tested with and without hot shoe spring.

-RX setup is Canon, EX580ii or USER EX550 (have tried both)

-TX Setups tried.....

- Camera sys - Autodetect Fuji, Flash Sys - Canon, EX580 or EX550 (have tried both), Learn HSS, Forced HSS ON

- Camera Sys - Fuji, Flash Sys - Canon, EX580 or EX550 (have tried both), Learn HSS, Forced HSS ON

In both cases, system radios set to short range.

Testing has been unsuccessful with any speed over 1/250th. in some cases, flash just does not fire, or it clearly fired but missed the shutter window. In other cases, there is banding

Hello BenofW

It probably the contact on the hot shoe is interrupted. I suggest to remove the hot shoe spring on the camera that will improve the connection. Please click the following click for the video tutorial,

In addition, you may be interested to watch the following video regarding the V6II setup for the camera. I used Fuji X-T1 and Nikon SB-910 in the video.

I hope that helps.

Dear everyone,
a result of my case were as follows.

X-Pro2 firmware Ver.2.00
Cactus V6II firmware Ver.1.0.108（beta version）
Flash units - Godox V850 (HSS Mode), mounted on the Cactus V6II
I removed the hot shoe spring.

V6II SETTING
-CAMERA SYSTEM : FUJIFILM
-FLASH SYSTEM : NIKON
-FLASH PROFILE : AUTO NIKON
-I Carried out “LEARN HSS”, on SS 1/1000
-FORCED HSS : ON

RESULT
-I can use the flash in a “NORMAL HSS” mode,
but I cannot use in a “POWER SYNC” mode.

From Godox FT-16 mounted on the Cactus V6II, send to V850 (HSS mode),
It showed the same result.

Thank you.

BenofW · October 2016

Ray, I did remove the spring. While this helped with the learning of HSS by the TX unit. Still no success.

I have tried multiple Canon flash profiles as well as the Canon Auto function. No success.

For me Cactus doesn't work even with beta firmware. Beta firmware also makes X-Pro1 unworkable.

X-Pro2 and X-Pro1 with beta firmware:

Cactus detects camera and flash

Flash fires but fires either too early or too late but the result is no flash in the picture.

No matter if the shutter speed is below or above X-sync. No matter if forced or not.

I'm using flash on top of my cactus or with TTL-transfer cable so only one unit.

With the latest official firmware, no issues with X-Pro1 with same setup.

Picture:

Beta firmware, flash did fire but at the wrong time as you can see.

Maybe I'm missing something but cannot find out what.

Antonio · October 2016

Hi @mikkokan, have you tried re-doing the LEARN HSS process?
As this sounds like a timing issue.

mikkokan · October 2016

Hi!

It doen't help. Updated the beta firmware again, and learned the HSS, result the same=flash fires but at the wrong time. It says that learning completed, seems like everything is fine.

I think that I'm doing this right, because I've used a cactus before and like I said no problem with the latest official firmware with X-Pro1. Now both of my X-Pro's doesn't fire flash with beta firmware at the right time.

My flash is Godox V860c, the is a profile pre-installed witch I choose.

Could it be my flash or the fact that I use only one unit so the flash is on top of my camera or connected with Canon OC-E3 cable? Others seems to use beta firmware with two units that I see on youtube.

edit.

I tried three times this:

Updated to beta->learned HSS->flash timing issue

Downgraded to official->leaned HSS->flash fires correctly

Official FW 100% success every time, so there must be something wrong with the beta firmware.

Yes!... you need at least two (2) V6 II transceivers to work, one transmitter and one or more receiver(s).

We never tested your TTL cable + 1 V6 II unit setup as this was not the proper method of triggering off-camera flash, let alone with HSS support.

Thanks!

mikkokan · October 2016

Ok, thanks!

But it works like this with the latest official FW using X-Pro1. And I like this method

Is there any possibility, you could check this out and make it work with this new FW? Or am I then only one using this method

edit.

I'm just thinking, why there is a hot shoe on top of Cactus if it was not ment to be used?

Just to make sure the result is same using this cable or putting flash directly on top of the Cactus. (works with official FW, not with beta FW). So there is something wrong timing with beta FW using Cactus's own hot shoe.

Antonio · October 2016

Well, I was referring to the TTL cord.

We have an X-Pro1 here. We will update the camera firmware and see if we can reporduce your experience.

Thank you.

Antonio · October 2016

We updated the our X-Pro1 and it's not working well either.

R&D will look into this and I will post an update as soon as we have it.

Thanks!

mikkokan · October 2016

Great, thanks!

I'm glad I contacted you, this is why we have communities and beta testers!

Antonio · October 2016

Thanks @mikkokan,

R&D is looking into this as I type.

BTW were you using 1.1.108? For the record we did put up a newer 109 but I doubt there would be big changes on Fujifilm.

Thank you and I will keep you posted.

mikkokan · October 2016

Hi!

It was V6II beta firmware (V1.0.109).

Thanks!

Nicolae · October 2016

I have a X-T10 and a X-Pro2 and I'm using a Canon 430 EX. With the official firmware my XT10 worked perfect on HSS to 1/4000 s and X-Pro2 anything to 1/250 (no HSS). With the beta firmware XT10 is not working anymore on HSS and the X-Pro2 is showing inconstancy. And yes, I removed the hotshoe spring on both cameras

Nicolae · October 2016

Actually my experience is similar with BenofW

Antonio · October 2016

Hi @Nicolae, are you using firmware version 1.0.109?

You can check the version by pressing A + D buttons while switching the V6 II to TX or RX mode.

Thank you.

Nicolae · October 2016

Hi @Antonio, I'm using 1.0109

Antonio · October 2016

Thanks @Nicolae,

Did you also go through the LEARN HSS on your X-T10?
.
.
.

...With the beta firmware XT10 is not working anymore on HSS...

What is not working? Does the flash not sync? Or did the flash not fire ay all?

... and the X-Pro2 is showing inconstancy.

Please clarify...
Does the flash only sync some of the time?
Misfires?
And flash failed to fire?

Thank you.

Nicolae · October 2016

The flash only sync some of the time. Sometimes the flash fire with a delay of aprox 1sec. If I turn off and on the V6 II (both Tx and Rx) and re "learn" it's ok for a while than the story start over.

I can use HSS on X-T10 without problems on the official firmware (104). For the X-Pro2 I'm waiting for the next official release. Hope it will work.

I have forwarded your findings to R&D.

We released the 1.1.005 this morning, with release notes to follow later, it is very similar to the beta 1.0.109. So for now I'd stay stick to 1.1.004 for your X-T10 and 1.1.005 for your X-Pro2 until we find out more what's wrong with the X-T10. Thanks for your patience during this time.

Nicolae · October 2016

Thank you very much @Antonio & Cactus Team. Finnaly my Fuji X-Pro2 is working perfect in HSS with firmware 105 up to 1/8000. I'm so happy!!!

Antonio · November 2016

Fantastic!

Thanks @Nicolae for helping us beta test the firmware too!

mikkokan · November 2016

It's working for me too! Godox V860C and X-PRO2.

Antonio · November 2016

It's working for me too! Godox V860C and X-PRO2.

Splendid!

Thanks for the update, @mikkokan

Hello everyone,

The issue I am having is in conjunction with the Fuji Xpro 2 and Nikon SB910 speed light.

I have completed updates on camera and V6 IIs as well as resetting them.

I have to use camera flash setup to: others (and not Fuji auto set up) otherwise the flash will not fire.

The main issue I have is when the v6 iis in NON HSS and using the camera flash synch speed of 250 I get a banding in the image as though I am firing the flash above its maximum synch speed.

I have also tried this with hotshot plate removed as well and the problem is still there, the only work around I can find is if I use a synch speed of 200 by rotating the front dial on the Xpro 2 however this is not utilising the maximum flash speed of the camera.

Has anyone else experienced this problem.

Ean
