Sekonic's new Litemaster Pro L-478D meter is the world's first touch-screen-operated light meter. It has an array of unique, must-have features for both motion and still story tellers. Its compact size is both instantly familiar and comfortable to use. The large LCD (2.7") displays ambient, flash, cine and a host of other information in a clear and understandable way. Settings are made by simply touching or sliding a finger over the screen.
The L-478D can quickly be calibrated to your camera using Sekonic's Data Transfer software and either Sekonic or X-Rite Brand targets or by manually inputting data to the DTS program or on the meter itself.
