Hi Rand.
Do you know whether setting an X1T's CFn 00 affects only the timing of the firing signal sent through its hotshoe? Or does it also affect timing of the firing signals it sends via radio to wirelessly-linked flashes?
Thanks,
Owen.
Take note: Since X1 firmware update V09, which provides for wireless "rear curtain" sync capability, flash sync timing (CFn 00) is not useable unless wireless rear curtain sync (CFn 04) is turned "OFF" (set to 00).
The X1 only sends one trigger signal and the flash sync timing will affect that signal no matter the shutter speed used and which trigger signal is being sent. That signal is sent to the wireless flashes as well as to the center pin of both the X1 transmitter and receiver hot shoes. Since all the Godox 2.4G HSS flashes pulse their flash when using HSS, this will not be an issue to incorporate a long duration flash, such as the RL600B, into the mix as most only require a setting of around 20 to optimize the flash exposure. You will not see the Godox flashes affected until about 60 or so when in HSS. Of course you will want to set your flash sync timing back to 00 when not using HSS, as I stated the X1 only sends 1 trigger signal so you could see the shutter curtain at or just below Max sync speed, depending on how much delay you have set.
I adapted my modifiers with the Bowens mount but I am still not sure if my Mola adaptation is ideal (the Flashtube is still sitting a tad deeper). Thoughts? I was cheap and I didn't want to spend $70 for the Mola/Bowens ring, so I used my own Bowens cheapo ring
