Sekonic L-858D-U Overview

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.

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).

The spot meter measures in foot lamberts rather than foot candles. I have never used foot lamberts before and I am finding conflicting answers to how many foot lamberts 250 foot candles is. I got the meter because I want to work with the zone system following Ansel Adams books. He talks about spot metering in foot candles and knowing that the moon, in Hernandes NM was 250 fc. Can someone point me to an easy conversion tool such as an ios app?
Asked by: Timothy
The Sekonic Speedmaster L-858D-U Light Meter can also be set to foot candles. This is mentioned on pages 44 and 69 in the user manual. Please take a look at the following link: https://bhpho.to/2XhpxtV

Does this have a t-stop mode? When working with ...

Does this have a t-stop mode? When working with cinema lenses that use t stops instead of f stops, how can I use this light meter?
Asked by: James
F/stops are arithmetically calculated based on the lenses physical size. The amount of light coming through the lens is therefore theoretical. This means two different lenses at f/5.6 could be passing different amounts of light. In the days of movie making film, this caused a great deal of problems for movie printmaking where the density of the image would vary greatly between shots. This would take extra time, effort and money to get a consistent print. To eliminate this problem, the 20th Century Fox camera department in the 1930's developed the T or Transmission stop. What they did is measure the amount of light coming through the lens and then set that as the T/stop. Since glass absorbs light, there is a light loss compared to f/stops. All this to say, there are no T/stop meters; they are all f/stop. Just read the meter, set that number on the T/stop ring and enjoy a consistent, lens to lens, exposure.
