Nauticam Mini Flash Trigger for Sony and Compatible with NA-A7/A7II/A7III/A7RIII/A7RIV/A9/A7S

The Nauticam Mini Flash Trigger for Sony is a compact, high-performance optical triggering system designed for reliable control of external underwater strobes. Installed inside compatible Nauticam Sony Alpha underwater housings, the trigger converts the camera’s hotshoe signal into an optical signal that is transmitted via fiber optic cable to compatible strobes.

Its fast and stable signal transmission enables dependable flash synchronization, even during continuous shooting and fast-action sequences. Designed specifically for manual flash operation, the Mini Flash Trigger provides a simple, efficient, and reliable solution for demanding underwater photographers.

With a battery life of approximately 10,000 flashes per set of batteries, compact dimensions, and broad compatibility with Nauticam Sony housings, it is an ideal choice for macro, wide-angle, and action underwater photography.
