The YS-120TTL Duo represented a milestone in flash technology. It was the world's first electronic strobe with internal circuitry that will automatically dedicate for TTL flash photography with both four-pin and five-pin connectors. The technology was so well-received that it became the forerunner of Sea & Sea's YS-30TTL Duo and YS-90TTL Duo strobes.Compact and lightweight, constructed of rugged thermopolymers Built-in prism diffuser projects an ultrawide 105º x 105º beam for corner-to-corner illumination Operates in TTL, full and 1/2 power manual Recycles fast Delivers flash readiness and TTL confirmation data via neon lamps and audible beeping signals built into both sides of the strobe head SpecificationsExposure control: Manual (Full, 1/2) and TTLBeam angle: 105º landGuide number (ISO 100, land): 72/22 (ft./m) (full power)Recycle time: (Full power/full charge): 2-3 sec.
