obstructions to avoid interference.
In S2 optical slave mode, the flash unit can be a secondary light source
in TTL flash environments. It features pre flash suppression, allowing
synchronized shooting when using a camera with a single pre-flash
function. It also synchronizes with the second flash from the main flash
unit, enabling the second optical slave triggering.
