Hi!
I have a Sony A6500 in a Nauticam housing and run dual YS-D2J strobes with S&S fiber optic cable II M/2 18". I recently purchased a UW Technics TTL-converter for a couple reasons, one of which is being able to exceed the camera's sync speed of 1/160 when the camera's flash is used (my understanding is that you can shoot up to 1/250 with that camera and not capture the shutter in the picture).
I set everything up for TTL operation and it appeared to be working, and I recall it would allow me to set a shutter speed faster than 1/160. I then followed the instructions to put the strobes in manual mode and tested that. Everything worked fine - still does in manual mode. When I went back to the TTL settings, two things happened. 1) My shutter speed was limited to 1/160 and 2) every picture was extremely underexposed - i.e., essentially completely black. If I crank up the flash comp to ~+3 EV, I can actually see what I shoot, but it is still underexposed.
I contacted UW Technics and they said that the issue is with the YS-D2J strobes, and their TTL circuitry. UW Technics has actually been helpful so far. They have been responsive and said they'd make me a new custom sample TTL-converter to try to address the problem - but that it will still likely have issues given the strobes. I was wondering if anyone else has any suggestions or has experience with trouble shooting this issue with these strobes?
The shutter speed issue is what is making me think that something has gone awry with either my camera or the TTL-converter. Am I crazy/misremembering what actually happened? I didn't think the shutter speed would be limited in TTL mode, but maybe I was mistaken? Any help is appreciated!
