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:


Strobe/LED flashlight Compatibility

The highly accurate “S-TTL” Auto mode of INON Z-240/D-2000/S-2000 is supported when connecting via INON “Optical D Cable Type L” products.

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

Good luck.

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.

I tried outside the housing with the same negativ result. 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. Okay that leaves me on manuell as in the last 6 years with the old simple strobe, only now with the Inon I have 13 instead of only 5 powersteps, which might help in some macro situations.
Thanks you all for your input

Hi there - I am reading your thread as I have the same problem.. I need to know how you solved the problem? Did you connect fiber optic single core to Inon Strobe?

Hello Bryan,
I sold my Sony together with the ikelite housing and got a 2. Hand Sony 6400 . Saw the results from a divebuddy using this camera
The Sony RX were good ,but they were better.
Especially the video quality.
Got a reasonable priced Seafrog housing.
The 6400 works with TTL but I must admit that manual shooting gives better result. With the time you get a feeling for shutterspeed and aperature in a given situation, especially in macro. Wide angel is a different Story, simply because there are more parameter to watch.
Kind regards
Peter

The info provided there is incorrect. I have been shooting Sony and Canon cameras with Inon strobes for over a decade, going on two decades. The Inon strobe, all models, is fully compatible with Sony cameras in sTTL with the Sony RX or A series cameras in Manual mode and Flash Fill.

The Sony RX and A series cameras are however not compatible with an Ikelite strobe and trigger that does not have preflash cancel as I have described in the other thread. For TTL to work the camera must fire a preflash for metering. Sony cameras, RX and A series, always fire a preflash and therefore have TTL available in all modes including Manual. What sucks about RX and A series Sony cameras is there is no option to do camera manaul flash fill with no preflash. Therefore all optical controlled strobes must be able to ignore the preflash and fire in sync on the following main flash that actually does the image exposure for manual controlled flash and in sTTL strobe mode fire both the preflash and the main exposure flash for image metering by the cameras exposure system. It sounds complicated, it is not in practice.

I generally shoot my Sony Nauticam NA6400 camera rig with the camera in Manual mode, camera set for flash fill, Inon strobes set in sTTL mode. If you have specific questions regarding Inon strobe operation and Inon sTTL and the magnet preflash/no preflash switch I can probably set you straight if you ask the right questions.

BTW, the sTTL switch selection is not active in strobe sTTL mode, the Inon strobe must default to preflash mode in sTTL because that is what sTTL is by definition regardless of the switch/magnet position. The Inon strobe magnet or rotary preflash/no preflash switch is only active when the Inon strobes are set to Manual mode.
