The Sekonic L-478D-U LiteMaster Pro Light Meter offers an array of unique, must-have features for visual storytellers. Its compact size is both instantly familiar and comfortable to use, and the large, 2.7” LCD screen displays ambient, flash, cine, and other vital information in a clear and readable format. Settings changes are made by simply touching or sliding a finger over the touch capacitive screen.

The L-478D can be quickly calibrated to your camera using Sekonic's Data Transfer software and either Sekonic or X-Rite brand targets, by manually inputting data to the DTS program, or on the meter itself. 

Still Photography Features

The L-478 features full Ambient-Flash modes, including new T-F mode. Measure, compare, and mix ambient and flash displayed on the color touchscreen for beautiful, controlled results.

DTS Exposure Profiling matches the meter to the performance of your camera (requires separate Sekonic or X-rite exposure targets and 5-degree finder for L-478). Precise exposure and lighting starts with precise, repeatable metering.

Cinematography Features

The L-478 features Cine/HD Cine modes for today's HDSLR and Video Cine cameras. Effortlessly switch between HDSLR and Cine for exact exposure settings in exact increments for both. This light meter also offers infinite frame rate and shutter angle selection. Create special settings for special applications.

A unique light-source filtration compensation mode enables precise control over lighting using industry standard CTO/CTB/ND types, at the touch of a finger. The L-478 also feaures illumination measurement and extended ISO range. 

NOTE: The L-478 series offers the following interface languages: Japanese, English, and Chinese. Depending on the country where the meter is purchased, the language is fixed and cannot be changed by the user.
