Very interesting. I have a message to Turtle with a diagram asking for alternatives. The unit is a little pricey, but depending on the comments from Turtle, I just may go for it.

Yeah, it's kind of mind-boggling how that tiny box costs more than the whole housing, or the strobe for that matter.

One question: The optical TTL strobe trigger works because it uses the two light pulses from the flashes on the RX100iv and a6xxx. Is it true that the sync cable does not work for TTL because two pulses are not emitted at the hot shoe connection?

Thank you,

Dave

No idea, I'm far from an expert on the subject matter. You might want to ask Pavel Kolpakov over at Wetpixel forums - he's bound to know. Also, a quick Google search coughed up this document describing various underwater strobe TTL sync protocols: http://g3ynh.info/photography/articles/ttl_flash_connexions.pdf
