Great for Photographers & Filmmakers

The Sekonic Litemaster Pro L-478DR-U Light Meter’s full-featured ambient flash modes include the new TF Priority Mode, which lets you measure, compare, and mix ambient light and flash for beautiful, controlled results. It expands on its standard stills functions with two distinct video modes: Cine and HD Cine for today’s HDSLR and Video Cine cameras, and lets you effortlessly switch between exact exposure settings in exact increments for both. These settings give access to frame rate selection from 1-1,000 fps as well as shutter angle settings from 1-358° as well as ISO 850 for Canon cinema cameras.

Large Touchscreen in a Compact Form

The L-478DR-U’s compact size is both instantly familiar and comfortable to use. Its large and intuitive 2.7” LCD displays ambient light, flash, cine, and a host of other information in a clear and understandable way, and its touchscreen controls make it easy to adjust settings. Ambient light measuring modes include aperture priority, shutter speed priority, TF priority, CINE, HD Cine, illuminance, and luminance.

Wireless Control

The L-478DR-U comes complete with exclusive PocketWizard ControlTL technology which lets you wirelessly control Nikon, Canon, and other select studio flashes with a touch of a finger.

Other Notable features

Guaranteeing the best possible performance is a suite of functions and features that will ensure users have the best tools available to them. Among these is a flash analyzing function that uses ambient and flash simultaneously to allow for shooters to dial in their preferred mix. Also, using the included Data Transfer Software users will be able to do Exposure Profiling for their camera by using the optional 5° viewfinder. Alongside this is a Filtration Compensation Mode that allows for the meter to account for filter factor, which can now be done at up to 12 EV for landscape shooters using high-density ND filters. Other features include a contrast function for comparing brightness, a memory mode for 9 readings, and illuminance or luminance measurement.
