Sekonic Light Meter LiteMaster Pro L-478DR-RADIO for PocketWizard. A large and intuitive 2.7" color touchscreen makes this light meter very easy to use. Combined with built-in radio control for PocketWizard ControlTL, the LiteMaster Pro L-478DR makes measuring both ambient and flash light simple and enjoyable. The system provides full control over flash power in 0.1-step increments. The radio module also offers individual zone control – 3 zones for ControlTL and 4 zones for standard triggering – with measured values stored to simplify ratio settings.
- Lumisphere measuring head that rotates 90° to the right and 180° to the left, and can be retracted for use as a flat diffuser
- Optional 5° viewfinder for spot metering
- Ambient light measuring modes: aperture priority, shutter priority, TF priority, CINE, HD Cine, illuminance, and luminance
- Flash metering via PC-sync, wireless, or radio triggering
- Measuring range at ISO 100: –2 to 22.9 EV (incident) or 3 to 19.9 EV (reflected)
- ISO range 3 to 409,600 in 1/3 steps, including ISO 850 for Canon Cinema cameras
- Additional functions: exposure profiling, mid-tone function, exposure compensation, filter compensation, multiple cumulative measuring, memory/clear/recall, average function, contrast function, auto power-off, panel lock
- Powered by 2 × AAA batteries (sold separately)
- Firmware upgradeable via mini-USB
The hallmark of the L-478 series is the large color touchscreen, providing quick access to all settings for both flash and ambient metering. The meter is highly capable, operating within a range of –2 to 22.9 EV at ISO 100. For today’s hybrid shooters, functionality is expanded with two dedicated video modes: Cine and HD Cine. These allow for selecting frame rates from 1 to 1,000 fps, shutter speeds or shutter angles from 1–358°, as well as ISO 850 tailored for Canon Cinema cameras.
To ensure the best possible performance, a wide range of features gives the user maximum control. A flash analyzing function combines ambient and flash light, making it easy to fine-tune the balance between them. With the included Data Transfer Software, the user can also create exposure profiles for their camera (requires the optional 5° viewfinder), revealing the camera’s dynamic range and ensuring accurate exposure. The Filtration Compensation Mode allows the meter to account for filter factors — now up to 12 EV — ideal for landscape photographers using high-density ND filters. Additional features include contrast measurement, memory for 9 readings, and illuminance and luminance measurement.
