Inon S2000 with Sony RX 100/2 ?? Need advise

[scubaozy]

Exposure has to be correct if you are testing ttl. Even strobe fires, it could be slightly early or late.
Here are people discussing inon with rx100m2&3. https://wetpixel.com/forums/index.php?/topic/63947-inon-s2000-with-sony-rx-100-mk-3/
I still think that this could be a testing problem, why on earth people would discuss it if it didn’t work..

I guess that the problem might be solved on the next dive trip ( 2022 hopefully) trying with or without the magnet on different dives ( not risking to loose it while changing underwater) . I never had to use fiber optical cabel so far, due to the great transparent Ikelite housing. And the good test results topside in manuell mode let me hope, that it will work as well with the Inon strobe. ( It fired even holding it behind my back - very sensitive)

Finally I got an answer from Sony , who told me that in my RX 100/2 the fill in flash in M mode does not work with the TTL of the Inon strobe - or any strobe.

I've had no issues using TTL with ys-03 and ys-d2 with my rx100m2 in manual mode, can't comment on the inon though.

I don’t think it will work. When you use the strobe in manual mode, it only needs an impulse from camera flash, the strength of the impulse is not that relevant. You might get away without using a cable.
Inon sTTL mode will mimic the cameras pre-flash and main flash. Strobe needs to copy the light from camera accurately, you need an optic cable for this.
Following statement is from previous link I shared:

I was thinking of this wireless set up from the Inon homepage, because it gives me the freedom of removing the strobe to reach further out or backlight ( I don't like the ultra long arms too much)
But I will take a cable or two just in case

I have never seen anyone actually use this kind of setup. Keep in mind that in order for it to work, the mirrors need to be carefully aligned to bounce the light in the proper direction, so it actually gives you far less positioning freedom in comparison to fiber optic cables - you need to set it up and then avoid moving the strobes in order to keep the system aligned. If you want to play with remote strobes, you need proper remote triggers, such as the Anglerfish.
