I Just got my Nauticam housing for my D7200. My old camera was a D90 and I triggered my Inons with sync cable.
Now I am using fiber optic, and that's where the trouble begins.
I have been setting everything up, getting ready for the first dive tomorrow, but I can't make the flashes fire.
I've had the flashes fire a few times, but then they stopped again.
I tried to flash my sola light directly at the slave sensor, and that triggered the flash every time.
The cameras flash are in manual.
Please telle me that I have overlooked something. What else could it be ?
