The Nikon Flash Trigger for Nauticam housings is quite possibly one of the best things to happen for those of us that shoot manual strobe exposure.


Gone are the days of seized or flooded bulkheads and reliance on expensive cables with o-rings that need constant attention. Those of us that shoot manual have always gravitated towards the cable release due to the high recycle time and independence of the internal flash (or lack there of, Canon 5D series). This forced us to have electronics inside the housing linked to bulkheads and hot-shoe connectors that we always forgot to connect. Enter the flash trigger. A lightweight plastic device that attaches to the D810’s hotshoe, producing small pulses of LED light that trigger my strobes via the housing’s built in fiber optic bulkheads.


Powered by two coin cell batteries, the Flash trigger is rated to 5000 flashes on a set of batteries. The batteries can be installed in seconds with clear instructions in the molded plastic as to polarity. A status light blinks unobtrusively to let you know the device is on and the batteries are ok. This flash can be seen just at the top of the clear rear panel of the camera housing from outside even with the unit installed. The recycle time is similar to cable release and since it doesn’t require the internal flash, it draws no battery power from the camera. The system does not allow for TTL but for those who choose manual strobe exposure, the flash trigger opens up the ability to use optical strobe firing capability without the battery drain of internal flash and the recycle time of a cable release without the o-rings.
