Originally posted by mcgregni Well you've asked about the TTL Passthrough "stack" on your other thread, and some general explanations about its use are already there. If you feel that the trigger / flash stack plus the ringflash is actually a practical thing to work with (another accident waiting to happen?), then yes, operate the Pentax flash in TTL Passthrough mode on the V6II, and the RF60x as a
Radio Slave controlled by the V6II.
If the whole contraption is too unwieldy then you've got the option, as UncleVanya said, of basic optical slave triggering. Here's the download for the RF60x Manual .....
https://www.cactus-image.com/Cactus%20RF60X%20User%20Manual%20(EN).pdf Originally posted by UncleVanya That is why one scenario I suggested was to put a v6ii trigger near the roundflash. Trigger the v6ii trigger using light in s2 mode then it can fire the rf60x via radio signal.
Okokok.... let's wait up for a second and see if I have this right.
I'm looking at the Manual for the RF60x, page 39-40 as suggested. It appears that when placing the RF60x into OPT SL S2 mode, it's going to be optically triggered from the 360ii, no need for a v6ii at all, correct? But this optical triggering can be a bit hit or miss right, depending upon ambient light, distance and all that kinda stuff? Really just the reverse of what I've done thus far with my RF60x and 360ii, in that I placed the 360ii in SL2 mode and it was optically triggered from the RF60x.
But I was under the impression if I were the have the K-1 with the v6ii and the 360ii on top of that, I'm not going to manage (regardless of firmware installed on the v6ii) to get the 360ii to work as normal (full functionality as if it were in the hotshoe) and then
also still have full functionality of the V6ii to control the power of the RF60x as per normal etc? If the 360ii can do HSS (which it can) and I can control it's power direct (as it's sitting on top of the v6ii (in Tx mode) in the hotshoe of the camera, we'd have to use bypass ttl mode, and wouldn't that then kill off any functionality and control over the RF60x?
And then also what about HSS?
I'm now just starting to put my head together for all sorts of working flash combos with the 360ii and rf60x, not just with the perhaps awkward ring flash. Currently I am with just one V6ii, but by the end of today that might change and I'll have two v6ii units which might open up the potential for working scenarios.
What's just occurring to me, is that the ring flash might make a nice fill light, and the 360ii is a less powerful flash, so it might suit that purpose. RF60x as a key light elsewhere. That would mean on location shoots I have a two light set up, one that's a softbox 'on camera' with me, leaving me with only having to carry a single light stand with a rf60x and a softbox (or magsphere). Could be quite a portable and easy two light set up if I could understand how to make it all play ball without missing out on features like P-TTL or HSS.
