I see references to it on some of the information regarding the Godox 685S (for Sony) yet mine can only select between A,B,C.

I see a note similar to this though regarding the Groups in those articles
"NOTE – There is no GR Mode with pre 2012 Canon Cameras – So only 3 Groups available then, and no mixed TTL & Manual)"
So is this GR Mode something Canon and Nikon may have but not available on my A7R3?
I mean, I can just set my AD200s to D and E and my AD600 to A thus leaving my two small flashes to Groups B and C but still I am curious about it.

Thanks

No. According to flashhavoc's TT685S announcement, you can only set a TT685S to Groups A-C.

This is also the case for the Nikon, MFT, and Fuji flavors. That is, everyone but Canon.

Only the TT685C can be set to groups D & E, and that's because Canon cameras can actually set Canon flashes to groups A-E. I suspect that Godox gear is reverse-engineered from Canon tech, and then adapted for the other systems. The fact that my TT685C can also do TTL ratios, but I'm pretty sure the other flavors don't is another indication of this, as is the changing backlight color for slave/master indication (which is how the Canon 600EX-RT does it).

The optical wireless flash systems that are used by everyone else are mostly limited to three groups (A, B, and C), and since that's all the camera can communicate, that's all that Godox has to work with. The only exception to this would be Nikon's new radio system, which allows for six groups; and Sony's new radio system which allows for five. But they've only reverse-engineered Canon's camera menu/flash communication protocol.

I think this is also why the non-Canon system flashes sometimes have to be set to TTL on the flash to allow for remote power control, even in M ratios.

Godox, of course, can build groups D and E into its own lights that don't have to ever communicate directly with a camera, but only a Godox transmitter. My Godox A1 can also be set to groups D&E as a slave. :)

Ok that clears things out..no need for me to think about it any more then :D Like I said, I can just set D and E for my AD200s but I was just curious about it so thanks for confirming that it is not possible for my case. :)
