Sekonic L-858D overview

  • 1Description

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).

    Sekonic L-858D reviews

    Speedmaster L-858D-U Light Meter is rated 4.2 out of 5 by 29.
    Rated 5 out of 5 by from My favorite meter of all time! This meter can handle anything. I got it for direct readout fstop readings for HSS portraits. The 858, to my knowledge, is the only flashmeter on the market with HSS readout. It performed flawlessly eliminating the chimping on HSS shoots. I also have calibrated the meter to several of my sensors (D500, D750, D810 Nikons). Once calibrated, the 5 degree spot can be used to measure the brightest point in a scene and ensure shoot to the right metering for landscapes (in my case). Instead of bracketing I now shoot one shot that ensures the scene will render within the dynamic range of each of my cameras. Nothing short of amazing.

    Rated 5 out of 5 by from Great Lightmeter! Originally I was going to pick up a second hand sekonic L-758, but then decided that the new features of this meter were worth spending a bit more. One feature I've used extensively so far is the spot meter function that lets you average 9 readings in memory. This has really come in handy when working with film that is usually a bit more difficult to work with such as Adox CMS 20 and Fuji Velvia 50. Shooting Adox CMS 20 in 4x5 and Velvia 50 in both 4x5 and 8x10 has a high cost per sheet, and this light meter helps to ensure that errors in exposure are rare if at all. Also, the fact that it now runs on a standard size of AA Batteries is a nice perk.

    Rated 2 out of 5 by from Mixed emotions... happy and disappointed at the same time. Product works well when reading in ambient or flash mode. Never had issues in these 2 modes. I bought this as an upgrade from my Sekonic 478 because I wanted to use it for HSS work. I have a Streaklight 360 and Xplor 600 which supports HSS. While in HSS mode, I am able to get the exposure reading without issues when I'm in a partial shade. However, When I am a direct sunlight, the subject is backlit by the sun, the L-858D's F-Stop reading just says - - or under. This happens to my L478 too so i know its normal for L478. But i guess L858D defeats its purpose if you can't get HSS reading in a sunny environment. On the other hand, if I use a ND filter, shutter speed 1/200, iso 100 and set the light meter to just Flash Mode, I get a proper reading..

    Rated 5 out of 5 by from Easy to use, well built, capable light meter. Very capable light meter. Easy to use and calibrate. Well Built. Uses 2 x AA batteries. The graphic interface is some what dated. I have never understood why camera equipment companies never seem to use modern iPhone/Android designers to update their user interfaces. Have not yet found a use for the flash durational analysis.

    Rated 5 out of 5 by from Indestructible!! Got mine from B&H and had it brought over to me in Central African Republic by a friend two weeks ago. While testing it for the very first time near my fence I somehow disturbed a hidden nest of wasps whose residents immediately went into a furious offensive. In my flight to safety, I dropped the L-758 one metre down onto the concrete drive way and my heart sunk. I was amazed, when I picked it up later, to find that it still worked perfectly! So far my few tests using it and the colorchecker passport indicate that it's one of the best investments I have ever made in photography. My exposures and colors are now dead accurate and I look forward to finding time to calibrate my cameras with it.

    Rated 5 out of 5 by from Excellent!!! A must have accessory for any cinematographer.. I've been using the L458, without the spot meter & have been missing the spot readings, which is critical in any shoots, mostly outdoors. The touch screen display is not as sensitive as with the cell phones, still it serves the purpose. Customizable shutter angles & frame rates is a good add-on to have. so is the filter compensation, even though i like to compensate for it manually. The battery life seems to be pretty decent. Overall I recommend it to anyone serious about accurate exposure,

    Rated 5 out of 5 by from Such a great meter for a cinematographer! I love this thing.� Coming from the 478, having an reflectance meter is awesome.� This thing will do just about everything.� The ONLY thing I have found that is a super-small annoyance is that the 478 displayed (fc) as well as your appropriate primary setting (aperture, shutter, iso, etc).� This model display of (fc) or (fl) is a separate mode.� The meter is easy to use.� It feels natural to use and the settings all come naturally.� Being able to quickly set your mid-tone for a cinematographer and see the dynamic range in your scene is fantastic.� Not only can you use a meter reading to set mid-tone, but you can choose it manually or from a memory.� That feature alone was worth the money invested.� Our cameras today can capture SO MUCH dynamic range, pushing beyond film, but a simple reference I can look at while having 3 people talk to me and not have to think... gold. I highly recommend this meter.� I think that its becoming a lost art.� Basically look at it a picture and decide what you like.� I'm a digital baby, thats the way I grew up in production.� Now that I'm at a point where I need to know lighting BEFORE camera comes in the door... this thing I worship.

    Rated 3 out of 5 by from Test before buy Mainly used in Cine mode. Start up each time seems to take forever. When I'm shooting I want to quickly grab a reading but have to turn on the meter and wait to go thru menu etc. Just a little thing but when it's hectic on set it's annoying.
