a7RII+Meikon Case+ST-100 Strobe

The strobe doesn't fire at all on the TTL setting through the Meikon case and 5 pin cable to the A7RII.

Bummer; has SeaFrogs support responded to clarify that?

In conclusion, it looks like my ST-100 all works as intended, which does not include TTL with the A7RII. Also, returning the ST-100 and buying a $700 Sea and Sea or Inon would not solve the A7RII TTL compatibility problem. I suppose I could buy an a6300 and the Sea Frog case for it in order to get TTL, but I'd rather have the high cropability of the A7RII. Considering price and my frequency of use, I think I'll stick with the ST-100 and use it in manual mode. Besides, I usually shoot under ambient and do adjustment in post.

If anyone has other information, I would appreciate hearing about it.

If ST-100 doesn't do TTL with electrical triggering then your alternatives are Ikelite ($1695 housing, $375 TTL kit, $799 per DS-160 strobe) or Nauticam ($2850 housing, €349 s-Turtle LED trigger - Nauticam's own trigger doesn't do TTL) with fiber optic strobes of your choice. Compared to Meikon, both options are prohibitively expensive - besides, from what I understand, many people shoot their strobes manually even when they do have TTL as an option, as in underwater conditions, TTL accuracy can be iffy.

Still, I'm kind of glad I picked A6300 as the camera system to invest myself in - I couldn't know it at the time, but it turned out to be the system that the manufacturer of the best value housings and accessories on the market decided to give their best effort to.

I wonder, what is the eventual successor to A6500 going to be like - an entry level offering to replace A6000? An 'A5' APS-C sports camera to complement the A9? An A6500R with a high-res sensor? Hopefully they'll keep the same body and control layout so that it will fit into existing housings...
