F20M and F43m Flashes with A7 wireless setup so limited?

I was trying to use F20M on my A7 as the trigger for F43m. The F43m is only triggered when set A7 to WL flash mode. But at the same time, the F20M will NOT contribute to the exposure no matter what flash comp I set on A7 body. When I set A7 flash mode reguler/slow/rear/ modes, the F43m will not be triggered at all. The F43m setting like RMT1 or RMT2 doesn't change anything.

So overall, the F20m can only serve as pure trigger, and I still just got one light source from a different position. Plus my RX100II cannot trigger F43m at all with either build-in flash or F20m mounted.

I mean seriously?? My cheap Youngnuo flash can be triggered on all above situations with or without exposure contribution from build-in flash. And the price is 1/6 of F43m.

Hmm.....If I'm not setting anything wrong, I'd really think of getting anther Youngnuo and sell the F43m.

The difference between the Yongnuos and sony flashes are TTL. If you don't use TTL at all, then the Yongnuos are a much cheaper option. Still nice to have one TTL capable flash for quick on-camera shooting though. The F20M lets you have off-camera TTL.

Try turning off HSS on the F43m

Can you provide more details? I don't see why HSS is directly related to wireless flash mode
