FrancyMak 0 Posted January 9 Hi. I'm having a bit of trouble understanding how TTL works in my flashes. I have two Z330s with a CanonRP and was told, as well as I understand from the website, that Inon offers electrical ttl via sync cables. However, my current hot shoe connector only has the X pin and the GROUND pin, so there is no exchange of information between the flash and the machine. Can anyone tell me if there is a way to make these flashes work with Nikonos 5-pin Sync cables? I was told that it is possible using TTL-Converters that have a price tag of about 400/500€ that I honestly would like to avoid spending. Thank you very much for your help!

You can get TTL when using optical triggering off a TTL-capable flash, like a pop-up flash on cameras that have it, or the little clip-on flashes that Olympus likes to use, or a TTL-capable LED trigger, but getting TTL over electrical sync cords requires a converter, which is specific to your camera vendor (Canon, Nikon, Olympus/Panasonic, Sony). Seacam strobes offer TTL with S6 electrical connections, as they have the TTL circuitry built into the strobe (separate Canon and Nikon SKUs for the older 150D model, both Canon and Nikon compatibility in the newer 160D), but I believe they're the only ones with that particular feature. That said, manual mode strobes is nothing to be afraid of underwater. I used to shoot TTL-only strobes, and when I moved to strobes with manual capability (Retra Pro), it took me maybe half a dive to get the hang of it. Even though I have a TTL-capable trigger (UW-Technics), I only use TTL on blackwater dives, and then not always - regular wide-angle/macro, manual mode is just a lot more predictable.

ChrisRoss 150 Posted January 9 Agree, with electrical sync cords it's manual only with INON flashes. If you want TTL, you need to do it via fibre optics and that means a flash trigger. Some models can do Nikonos TTL protocol but only on film cameras , otherwise they need converters. If you already have cables, then you can use them in manual mode. If your housing allows it I would look at optical triggering if you wanted to use TTL. Share this post Link to post Share on other sites
TimG 62 Posted January 9 Back in the day (so, 2010-ish).... you could get TTL with Inon Z240s using electrical sync cords through the Heinrich Weikamp convertor. It worked really well for macro. It looked like a test tube - about 4" long with a bunch of electronics in it. I used it happily on a Nikon D300 while running a dive operation in the Lembeh Straits. I think divegypsy bought it off me years ago. Share this post Link to post Share on other sites
