Godox TT685S on V6IIs
Just for info - this flash is not listed as compatible with V6IIs, but I've managed to make the following setup work fine in the TTL, HSS, and manual modes:
Sony A7iii + V6IIs in TX <-> Godox TT685S on V6IIs in RX
It might be worthy of note that this wireless setup allows manual power adjustment from 1/1 down to 1/256, while the lowest power level of the flash itself is 1/128 (in Manual). Probably in TTL the adjustment range of the flash is broader.
Continuous shooting is only possible with the 'Lo' speed which is 3 fps for A7iii. At the higher speeds the flash fires only in the first frame.
The flash zoom is controllable from the V6IIs on the camera.
