If Godox wants to take a leadership position they should, in my view, build a 600EX-RT compatible V580 ETTL speedlite that also has a Cells IIc trigger capability to support the 180/360 lights in H mode.
It seems to me the main market demographic for this lighting system is event/wedding photographers. We want/need ETTL capabilities. Personally, the 600EX-RT Gr mode is the best solution currently available. Yongnou has been smart enough to recognize that requirement.
Adding Lithium-Ion and bare tube would make it perfect.
something that Godox won't touch,
barebulb flash with wireless capability and TTL
at this point, Quantum Trio still wins
