Sekonic Speedmaster L-858D-U Light Meter

The Speedmaster L-858D-U Light Meter from Sekonic is designed to meet the requirements of both photographers and filmmakers, featuring a comprehensive array of enhanced functionalities that render it an indispensable instrument for professionals in the field. This light meter is capable of measuring both incident and reflected light for flash and ambient conditions, with an impressive measuring range of -5 to 22.9 EV at ISO 100, or an illuminance range spanning from 0.1 to 2,000,000 lux. Its user-friendly interface, facilitated by a 2.7″ color touchscreen LCD and a robust all-weather construction, ensures ease of use.

The device is equipped with a 270 rotating and collapsible lumisphere, as well as an integrated 1 spot viewfinder, allowing users to adapt to various lighting scenarios. Furthermore, it includes a wide array of settings tailored for cinema and video applications, along with the distinctive capability to measure flash duration and capture readings during high-speed sync flash operations. The L-858D-U also boasts numerous additional features, such as memory recall, a Flash Analyzing Function, and extended ranges across nearly all settings. Moreover, users have the option to enhance functionality through optional modules that provide radio triggering support for PocketWizard and Elinchrom/Phottix systems.

• Lumisphere receptor head rotates 90 right and 180 left and retracts for conversion to a flat diffuser.
• Integrated 1 spot viewfinder with full information display provides a precise method of measuring specific parts of a scene.
• Ability to measure flash duration within a range of 1/40 to 1/55,500 second using t0.1 to t0.9 settings.
• Improved sensitivity of the L-858D-U allows it to record a reading at just 0.1 lux illuminance as well as use expanded range of -5 to 22.9 EV for incident readings and -1 to 22.4 EV for reflected light. Also, it features an extended ISO range of ISO 3 to ISO 13,107,200 with an option available for ISO 850.
• Optional radio modules are available for PocketWizard and Elinchrom/Phottix systems for advanced wireless triggering and remote flash control.
• High-Speed Sync support allows photographers to accurately take readings while using HSS with their flashes and cameras.
• Flash Analyzing Function measure ambient and flash simultaneously to provide a percentage of flash in the final exposure. Users can then adjust the mix as the display shows camera settings and the relationship between the flash and ambient light in your exposure.
• Users can determine the dynamic range of their camera using optional targets by taking bracketed shots with their measurement data and they using the Sekonic Data Transfer Software to graph and then save the information to the meter.
• Expanded shutter speed ranges now allow for readings between 1/64,000 second to 30 minutes with ambient light and 1/16,000 second to 30 minutes for flash.
• A comprehensive set of cinema modes allows for settings of 1-1000 fps as well as shutter angles of 1-358. Twenty user determined settings are also available that provide more precise options of 0.001-360 shutter angles and 0.001-99,999.999 fps.
• 2.7″ color touchscreen LCD provides a fast and intuitive method for viewing and changing settings.
• Micro-USB port can be used for firmware updates, applying custom settings, and to use exposure profiling.
• The L-858D-U features an all-weather construction that is dust and splash proof (JIS Class 4).

Sekonic RT-GX Godox Transmitter Module

Enhance your Speedmaster L-858D-U light meter by incorporating the RT-GX Godox Transmitter Module from Sekonic, which features a 2.4 GHz Godox-compatible radio triggering protocol. This module can be seamlessly integrated into the meter’s housing and offers a variety of functions beyond mere triggering. It grants access to 32 channels, accommodates up to 16 groups, and includes Wireless IDs for remote triggering within a range of 98.4 feet. Additionally, this radio control allows for adjustments to the modeling light power, supports high-speed sync (HSS) flash metering, and facilitates Godox users in measuring the ambient-to-flash light ratio and flash duration with greater ease.
