V6 II with Nikon D2Xs & SB800 / SB80DX
My units recognized both camera and flashes and seemed to fire and sync all right... or that's what I thought!
After a few months with no use at all, I needed them again and my nightmare started. My D2Xs mounts a TX and fires the RX and adjusts the head zooms normally, the power settings do change between 1 and 1/128 as they should, but the amount of light delivered is always the same. I made step shots at 1, 1/2, 1/4, 1/8 and so on till 1/128 and the flashlight is constant, doesn't vary at all, only when changing the F stop on camera.
I've been testing both flashguns with the Cactus system, without it (on manual), with the SC 29 cable, as Master/Slave (each speedlight) and the results are so confusing that I'm becoming crazy.
Today I just updated the firmware and sometimes the camera gets blocked, or it fires but the flashes don't sync at a given power...
¿What can I do? I appreciate your help, thanks.
