overview

Sekonic Speedmaster L-858D-U is the world's first multi-function, multi-brand wireless triggering light meter. It is the first of its kind capable of measuring flash duration and brief flash bursts like you find from HSS (High Speed Sync) for precision flash control.

The Sekonic L-858D-U is kitted with the RT-BR transmitter module. The RT-BR is a user-replaceable radio module that fits neatly next to the batteries in the SPEEDMASTER L-858D Light Meter. 

This kit brings a fully integrated light metering workflow to broncolor users, making it possible for them to measure effortlessly, control, and analyze the characteristics of flash like never before. The Sekonic RT-BR simplifies the process of lighting a portrait, analyzing a scene and helping you quickly dial in your lighting recipe to get to your final image with exacting precision.  

Full Radio Compatibility

The L-858D with the RT-GX transmitter module enables you to call upon all 99 Radio Studio Addresses (1-99), 40 Lamp Addresses (1-40, All) to remotely trigger their Broncolor lights up to 100ft away. You can even wirelessly control the power of modeling lights as well.

Next Level Flash Analysis 

Broncolor users can more easily measure the percentage of flash in their images to maintain the desired mix of ambient and flash. Measure flash duration as well to know how much stopping power your lights have to freeze the splash from their favorite product shot, or the pose of a ballet dancer.
