Sea And Sea Strobe YS-250 PRO:
YS-250PRO
Our new YS flagship model for professionals is fast and powerful with broad coverage: guide number 32, beam angle 105.
Amazing power to help you capture any subject you aim at.
The YS-250PRO is designed for demanding professionals, 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 Ni-MH 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.
