Sekonic L-858D-U Speedmaster Light Meter Kit w/ Transmitter Module – Godox

In the Field with the Sekonic Speedmaster L-858D-U Light Meter

Improve flash metering efficiency and accuracy with this Sekonic L-858D-U Speedmaster Light Meter Kit with Transmitter Module, which pairs the advanced L-858D-U light meter with the RT-GX Transmitter Module for wireless radio control via the Godox triggering protocol.

Aiming to provide for the needs of both photographers and filmmakers, the Speedmaster L-858D-U Light Meter from Sekonic comes packed with a variety of upgraded features and capabilities that make it an almost essential tool for a working professional. It is able to take incident and reflected light readings of both flash and ambient light with an expanded measuring range of -5 to 22.9 EV at ISO 100, or within an illuminance range of 0.1 to 2,000,000 lux. Users will also find it intuitive and easy-to-use thanks to the use of a 2.7″ color touchscreen LCD and an all-weather design.

The meter can use either a 270° rotating and collapsible lumisphere or an integrated 1° spot viewfinder to account for varying needs of the user. Also, it offers an extensive range of cinema and video settings as well as the unique ability to measure flash duration and to take readings when using high-speed sync flash. The L-858D-U is equipped with a variety of other functions as well, including memory recall, a Flash Analyzing Function, and extended ranges on nearly every setting. Additionally, through the use of optional modules, users can add radio triggering support for PocketWizard and Elinchrom/Phottix systems.

Add a 2.4 GHz Godox-compatible radio triggering protocol to your Speedmaster L-858D-U light meter with this RT-GX Godox Transmitter Module from Sekonic. Able to be fitted into meter’s housing, this module provides multiple functions beyond triggering, including access to 32 channels and up to 16 groups and Wireless IDs for remote triggering within a 98.4′ range. This radio control also permits adjusting the modeling light power, supports high-speed sync (HSS) flash metering, and enables Godox users to more easily measure the ambient-to-flash light ratio and flash duration.
