Sekonic's LITEMASTER PRO L-478-Series meters are the world's first touch-screen-operated light meters. They have an array of unique, must-have features for both still and motion story tellers. Their compact size is both instantly familiar and comfortable to use. A 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-478 meters can be quickly 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.

Keeping pace with wireless advancements, the L-478DR-U-PX comes complete with exclusive Phottix wireless triggering technology which combines light measurement with triggering as selected Channels and Groups providing amazing control in your hand. .

The L-478DR-U-PX has a radio module and antenna built into the meter. The system transmits at 2.4GHz and uses the Phottix Strato II signal protocol that can trigger channels (1-4) and groups (A,B,C,D) to fire any flash or Studio strobe connected to a Phottix Strato, Strato II, Ares II, or Atlas II receiver as well as a Phottix Mitros+ flash or an Indra 500/360TTL strobe set to Strato II receive function. When shooting, photographers can pick from various Phottix transmitters including the Strato II , Ares II , Odin or Odin II.
