Product Information
SEA & SEA YS-03 SOLIS (does not include fiber-optic cable). The Sea & Sea YS-03 Solis is a compact underwater strobe built for TTL flash photography, with a guide number of 20 (ISO 100/m, land) and a depth rating of 75m/250ft.
Who it is for
The YS-03 Solis is built for underwater photographers who want TTL strobe exposure without manually adjusting output: the strobe mimics the intensity of a camera's built-in flash and works with any camera housing that has a pre-flash and a TTL flash exposure function, regardless of camera make. It ships with a diffuser as standard, which softens and more evenly spreads the light output.
