Product Description


Our Flagship YS strobe for professionals is fast and powerful with broad coverage.

The YS-250PRO is designed for demanding professionals and is packed with revolutionary new features to meet the challenges of digital photography.
A large circular arc tube emits a powerful flash at guide number 32 (its value on land, ISO 100/m) when power is set to FULL. It provides incremental manual flash power adjustment in 12 steps for graduations of light.
The YS-250PRO is lightning fast: it recycles in 1.8 seconds. Its high-capacity NiMH battery, designed exclusively for the strobe, stores enough power when fully charged for 200 full flashes. A high-luminosity white LED target light in the center of the strobe shows precisely where the strobe is pointed, and a ready lamp and a TTL confirmation lamp on each side of the strobe indicate when the strobe is charged and when it has been controlled by the camera's TTL. An audible signal sounds when the lamps light so you can concentrate on your subject in the viewfinder.
The YS-250PRO includes other sophisticated features such as three fiber-optic cable sockets (2 with slave sensor) and pre-flash cancellation that handles up to two pre-flashes from a camera.

The YS-250PRO: at home in the water day or night, satisfying your demands for the best possible images.
