For the group. Obviously, if you're not using TTL gear, setting the group to TTL doesn't work. But if you have a TTL light (AD200, V1, V860II) in Group A, and a TT600 on Group B, then Group B has to be in M for the power control to work properly. But Group A can be in TTL with FEC.

I stand corrected; I don't shoot Pentax and I don't have an X2T. I mostly go off Canon Godox system knowledge, and I keep forgetting Canon has the most functionality under Godox. The X2T Canon, Nikon, and Sony hotshoes are fully TTL-dedicated; it looks like the Olympus/Panasonic, Fuji, and Pentax ones are are not. YA different-system quirk to catalog [eyeroll]. Hang on... yup. Single contact on the X1T-O and X1T-F, too. Huh. Wonder why.
Quote: I was insufficiently clear, I fear and it may be that Godox may actually support this sort of thing. I sometimes use a mix of P-TTL and the YN560 III speedlights with the latter optically triggered by the former.* ... *Have actually done a hacked SSH using the speedlights at full power with S2 optical triggering from an almost-nonparticipant P-TTL unit ...the duration is greater than the shutter dwell.
That's a clever way around the pre-flash timing issues.
Quote: It would be nice to be able to mix the two with a wireless TX. The way it might work...
- Godox X2T-P II or R2 Pro II triggered via wired PC
- On-camera or built-in P-TTL (with or without optical slaves)
- R600 speedlights controlled by TX
The enabling part is that the PC sync on Pentax is a separate circuit from the P-TTL sync. It only fires once and will do so at X-sync speed and below regardless of whether a P-TTL flash is active in the hot shoe.
Yeah, that might work.
