Nauticam HSS TTL Converter for Sony (NA-A1 / A9 / A7)
Accurate optical TTL and high-speed sync for Sony full-frame housings
This converter fits inside compatible Nauticam Sony full-frame housings and turns the camera's flash signal into a fibre-optic trigger with TTL auto-exposure and high-speed sync (HSS). TTL takes the guesswork out of strobe power for changing subjects, while HSS lets you sync flash beyond the normal shutter-speed limit for brighter backgrounds and motion control. Fires supported strobes over fibre-optic cable — no electrical bulkheads to flood.
Consider this if:
- you shoot a Sony A1, A9 or A7-series camera in a compatible Nauticam housing
- you want reliable automatic (TTL) strobe exposure
- you want high-speed sync for sunlit shallows and fast subjects
