The Sekonic Litemaster Pro L478 series are the world's first touch-screen operated light meters with unique features for both still and motion imagers. The layout of the compact and lightweight Litemaster Pro L478DR is easy and comfortable to use. The large 2.7-inch colour screen displays ambient, flash, cine and other information in a clear and understandable way. Settings are a breeze to customise and amend by simply touching or sliding a finger over the screen. The L478DR incorporates PocketWizard wireless technology for in-meter power control of select studio flashes connected to PocketWizard ControlTL receivers as well as triggering with the entire PocketWizard wireless family. The meter also uses Sekonics DTS system that automates meter calibration to the camera in use with either Sekonic or X-Rite Brand targets or by manually inputting data to the DTS program or on the meter itself.
