Sea & Sea YS-17 TTL Strobe

The YS-17's small body makes it easy to use underwater and easy to travel with.

It is light weight (477g including batteries) making it the lightest, most compact strobe in the YS strobe lineup.

The YS-17's system uses a unique TTL function so anyone can easily enjoy TTL photography. Even if the distance to the subject changes, the YS-17 will automatically adjust the light level so you can easily get the correct exposure. You can also switch between TTL and manual mode so you do not miss any opportunities for a great picture even in those situations, like dark places, where the TTL function does not work very well.
