Engineered for versatility, the L-478D-U offers a wide metering range of -2 to 22.9 EV at ISO 100, making it suitable for everything from low-light shoots to brightly lit outdoor scenes. Flash exposure can be controlled in precise 0.1-step increments, with readings taken either via PC sync terminal or wirelessly. Photographers can use the Flash Analyzing function to fine-tune the ratio of ambient and flash light, while filmmakers will appreciate the dedicated Cine and HD Cine modes for setting frame rates from 1–1,000 fps and shutter angles from 1–358°, including support for ISO 850—ideal for Canon cinema cameras.

Professional-grade features ensure optimal exposure in any scenario. With Exposure Profiling (via the optional 5° viewfinder) and Filtration Compensation Mode, users can account for their camera’s dynamic range and filter factors—up to 12 EV, perfect for ND-heavy landscape shooting. Additional tools like contrast and average functions, memory for up to 8 readings, and illuminance/luminance measurement modes provide further precision for lighting analysis.

The rotating lumisphere head moves 90° to the right and 180° to the left, and retracts for flat diffusion. The unit operates on 2 AAA batteries, features an auto power-off function, and can be updated via mini-USB firmware upgrades.

Whether you’re a cinematographer, studio photographer, or content creator, the L-478D-U delivers accurate, real-time metering with a streamlined, touchscreen experience.
