    Posted: 23 April 2019 at 11:49
I used to have a Mecablitz flash. I could easily control it as WL slave using the built-in flash of the following cameras : Dynax 7D, A700, A77 II. [WL designates the Wireless setting of the camera]

Using the built-in flash, I can trigger the Godox optically in S1 or S2 mode (on first or second flash, skipping the "Preflash TTL"). Of course, it only works in Manual mode.

I am quite confident that a suitable M)aster flash on camera can control the Godox as WL slave, using so-called CTRL+ protocol. This way, I'd get Manual and TTL mode as well.

But somehow, I can't do that using the built-in flash. This forces me to control the slave using a radio accessory or flash.

Am I missing something ?

Sony pop ups don't have Master flash capability so we're stuck with having to use a trigger or a mounted master flash.

What is the reason for that confidence? What exactly does the user manual say about it?

The pop-up flash on every Sony A-mount camera can act as a wireless controller, so it should be able to control some Sony-compatible Godox flashes (like the TT685s) but definitely not others (like the TT350s). Is it your experience that it can't control any Godox flashes?

1/ I am confident for two reason. First, the user manual treats the optical and radio wireless modes similarly, hence I transpose my certainty from radio experience. Second, when installed on A77II, the V860IIS reacts to WL setting on camera by enabling its optical M)aster state, as stated in manual. The screen labels this mode as CTRL+. It lists 3 groups of flashes : M (itself as Master), A (further qualified as RMT1) and B (RMT2). Each group can be individually turned off, or enabled in TTL mode or enable in Manual mode, with variable output.

My son also owns a V860IIS, so I intend to test a master/slave optical setup ASAP and report a definitive answer. I guess this will also be applicable to other brands of slaves, including Sony.

2/ As indicated by my Mecablitz experience, the popup flash is indeed capable of wireless control of some slaves. Let's call that Popup Wireless. There is no notion of groups. In particular, the popup is used exclusively as controller, and it's unable to significantly contribute to total exposure, unlike CTRL+ should.

Therefore, I conclude CTRL+ is a more complex protocol than Popup Wireless. For some reason, the V860IISS does not seam to recognize the simpler Popup Wireless. I have sent an e-mail on the topic to Godox support and will post their answer.

3/ Unlike the V860IIS, the TT350S has no optical mode (except for S1 / S2 triggering in Manual mode only). I purchased one primarily as a better option than a radio controller because it does fill flash, too, for little extra money. Highly recommended.

Additional note : As far as I can tell; the V860IIS is functionnally identical to a TT685S with a Li-Po 11.1 volts battery instead of 4xAA. More flashes per chharge, faster recycle.

As optical Master, it lists group M, A & B. As radio Master, there's an extra group C.

The Godox X Pro S radio controller seams to have two extra groups D & E, but the godox units I own (V860IIS and TT350S) are limited to slaves A B & C. More than enough for me.

At the Godox page under Master and Slave flash it says the C and N models can be controlled by flashes and by pop up commanders and gives body examples. For the S model it says "as a slave unit under control of Sony camera flashes e.g. HVL-F60M, HVL-F43M AND HVL-32M" with no mention of pop up command flashes.

I think the old flash protocol was known as CTRL/CTRL2, and the newer one is known as CTRL+/CTRL1. Although I haven't seen anything definitive on this, it's possible that the pop-up flashes support only CTRL/CTRL2 (which is still supported in all Sony flashes) while Godox units support only CTRL+/CTRL1.

If it hasn't been mentioned already, you should check out the Bible on flash setups
Miranda F & Sensorex, Sony A58, Nex-6, Dynax 4, 5, 60, 500si/600si/700si/800si, various Sony & Minolta lenses, several Tamrons, lots of MF primes and *far* too many old film cameras . . .

Thanks for the link. If I'm not mistaken, in the "Bible"

- what I called Popup Wireless is called "Generation 2: Wireless HSS and Digital". Specifically there is "no ratio flash".

Therefore, the popup flashes don't support the CTRL/CTRL2 protocol.

- the V860IIS sticks to "Generation 2: Digital Ratio Flash", in the CTRL+ variant (up to 3 flash groups).

Therefore, unlike the best Sony Flashes and my defunct Mecablitz, the V860IIS does not support "Gen 2 Wireless".
