I have not posted in quite awhile. I am looking to convert my aquatica D300 to fiber optic. I know awuatica makes the fiber optic bulkheads, but how to trigger tmem ,as there is no way to pop up the flash. There was a manufacturer that for awhile sold a small board that popped into the flash shoe on the camera, and had 2 leds on it. This sent a signal to the bulkhead fittings. Does anybody remember who manufactured this item ?
