Cactus V6 II cannot control flash power
I just purchased two V6 II transceivers and one RF60 flash unit.
My camera is Fujifilm X-Pro2.
Yesterday I found out that with shutter speed at 1/250 or 1/125 I did not get any light from my Sigma EF-530 DG (for Nikon) or my Fuji EF-42 flash. At 1/60 it worked ok.
Then I upgraded the firmware in the V6II to 1.1.106, the most recent, as far as I can see.
With this new firmware I cannot control the flash output to 1/2, 1/4 etc. It seems like the flash gives the correct amount of light to get a correctly exposed photo, even if the power is set to 1/128.
Maybe I have made some wrong settings on the V6 II.
With the V6II on the camera and the RF60 flash, everything works fine.
The problem is with the Fuji flash and the Sigma for Nikon flash.
Another problem is with the Nikon SB-800. It does not work at all with the V6II. To solve that problem I set it to SU-4 and let it fire on the light blink from the other flashes. But then I have to run over to flash in order to adjust the flash output.
I hope there is an easy solution to this problem.
