s-TURTLE SMART 3 – Manual Trigger for Sony Mirrorless Cameras

Manual flash control via fiber optic or sync cord – now in the powerful SMART 3 version.

The s-TURTLE SMART 3 is our latest-generation trigger designed for Sony’s high-end mirrorless cameras. This is more than a name update – it features all-new hardware, upgraded software, and expanded compatibility with today’s most advanced underwater strobes.

It is the perfect solution for professional underwater photographers who require manual exposure, smart operation, and broad compatibility with both cameras and strobes.
