The Skyport Plus HS Hi-Sync Transmitter enables you to extend the flash sync speed range of a Sony camera up to 1/8000th second with any Elinchrom Skyport RX equipped flash head. Hi-Sync technology allows you to freeze motion, overpower the sun to balance bright sunlit backgrounds with the foreground subject, use a wider aperture, and provides many other creative opportunities. It’s also easy to set up – just a few test shots are required to adjust the transmitter to the flash unit using its Over Drive Sync (ODS), and then you have up to 5 stops extra range to play with. Up to 10 heads in 4 groups can be controlled from the Plus HS, with both power setting and modelling light output adjustable. Powered by 2 x AA batteries, the unit has an integrated AF illuminator and can be updated when required via a mini USB port.
