Sekonic L-758DR/401758 Overview

  • 1Description

The Sekonic L-758DR DigitalMaster is the world's first multi-function light meter that can be programmed to match and be calibrated to the sensitivity of your digital camera sensor or type of film for perfect exposure control.  They have produced an incredible meter that more than meets the needs of the photographic community. This full-featured meter will definitely make everyone happy as it is loaded with every imaginable feature - and then some...

Expanding on the unqualified success of the L-558R, Sekonic has taken the next step and designed a meter that offers advanced features such as Spot/Incident measurement modes, flash/ambient measurements, flash analyzing, built-in PocketWizard wireless triggering, plus Exposure Profiling, Pre-Exposure warning, 14 selectable custom settings, and much more. This weather-resistant meter not only meets the needs of the digital community but can also serve the cinema community. The L-758Cine model will have expanded cine speed (fps) 1 thru 1000, Lux 0.63 to 190,000, Foot-Candle 0.10 to 180,000, Cd/m to 190,000, Foot-Lambert 0.07 to 190,000 and Preset filter compensation values (including Kodak Wratten filter number)

The L-758DR measures light beyond the capabilities of your camera and ensure repeatable accurate and consistent measurements. In addition, the dynamic range of a particular digital camera or film can be stored, recalled and displayed. Using the USB transfer cable (included) and the Sekonic Digital Input and Transfer software (included), a digital camera or film's exposure profile can be uploaded from a computer (Macintosh or Windows) to the L-758DR.

Up to three different digital camera or film exposure profiles can be saved and quickly retrieved with a touch of a button. With its Pre-Exposure warning indicators and adjustable mid-tone settings, the L-758DR puts the power of digital exposure control in the palm of your hands.

When you need to take a light reading - think Sekonic.

Important: To comply with local broadcast regulations, Sekonic wireless systems sold in the various markets around the world are designed to operate at different frequencies. When purchasing and/or installing a transmitter module or using the meter with a receiver, be sure that the meter, module and receiver are designed to be used in your location and use the same frequency.

The FCC designation indicates the meter and module are designed for operation in the USA/North American market. Frequencies: CH 1 to 16: 344.0 MHz; CH 17 to 32: 346.5 to 354.0MHz

The CE designation indicates the meter and module are designed for operation in European countries. Frequencies: CH 1 to 16: 433.62 MHz; CH 17 to 32: 434.22MHz

When purchasing and/or installing a transmitter module or using the meter with a receiver, be sure that the meter, module and receiver are designed to be used in your location and use the same frequency.

The wireless flash triggering system used in Sekonic meters consists of two parts that are designed to be used together and operate only at a specific frequency. Do not install a CE marked module into an FCC marked meter or FCC marked module into a CE marked meter as this will produce a unit that is not compatible with either frequency.

Exposure Profiling
In order to achieve correct exposure profiling with the 758DR, you need to purchase the optional Exposure Profile Target II. Once purchased, your meter becomes programmable to respond to light exactly like your digital camera or type of film; The L-758DR can be programmed to perfectly match the sensitivity of a digital camera sensor or type of film for perfect exposure control; In addition, the dynamic range of the digital camera or film can also be stored. Up to three Exposure Profiles (digital cameras, types of film, file type or file type) can be stored and recalled quickly and easily. Exposure profiles can be created for the following measuring modes:
  • Reflected measurements (calculated from ISO 3 to 8000)
  • Ambient measurements (calculated from ISO 3 to 8000)
  • Incident measurements (calculated from ISO 3 to 8000)
  • Flash measurements (calculated from ISO 3 to 8000)
  • Four Meters In One
    Independent programming of Flash, Ambient, Incident and Reflected measuring modes customized to your digital camera or type of film
    Working together (Incident and Reflected modes)
    Measured values can be memorized and retained in both reflected and incident measuring modes; For example: A incident reading can be retained and displayed as a diffused mid-tone on the analogy scale (f-stop or EV scale), at the same time as reflected spot reading of a highlight or shadow can be measured and memorized; The result is a Highlight, Mid-Tone and Shadow measurement displayed on the meter's analogy scale
    Spot with Digital Display
    The L-758DR DigitalMaster features a rectangular 1° parallax-free spot viewfinder; In dim or bright light situations, the L-758DR DigitalMaster's spot viewfinder displays f/stops, shutter speeds and more; The built-in spot meter measures both reflected ambient, flash or combined lighting
    Pre-Exposure Warning
    Displays and alerts when a measured value exceeds your digital cameras (or type of film) dynamic range
    Super Sensitive Flash Metering
    Measures light beyond the limits of any camera (reflected flash measurements as low as f-2.0 (ISO 100)
    1° Spot with Digital Display
    Rectangular 1° spot viewfinder with vivid display
    Mid-Tone Adjustment
    The Mid-Tone button acts as an exposure shift, moving the highlight or shadow within the dynamic range of the digital camera or type of film; Once the desired high light or shadow setting is selected, the pre-exposure blinking alert icon stops flash, indicating that the value is within the recordable range
    Retractable Lumisphere
    A built-in adjustable incident dome (Lumisphere) provides full measuring in the standard position or when retracted, provides cosine-corrected light readings for individual light source measurements or flat artwork
    Analyzing Function
    Simultaneous reading of flash and ambient light is analyzed and displayed
  • Combined readings of flash and ambient
  • Percentage of flash in the total exposure
  • Simultaneous display of flash, ambient and combined readings on the analog display
  • Exposure, Calibration and Filter Compensation
    Independent incident and reflected exposure compensation of up to +/-9.9 EV can be easily set for custom film exposure corrections or for bellows extension factors; With the calibration, compensation setting of +/-1.0 EV, matching built-in camera meters or other handheld meters is a snap; There is even a filter compensation setting of +/-5.0 EV for filter factor compensation
    Data Transfer Software
    Compatible with both Windows and Macintosh computers, the Sekonic Data Transfer Software automatically calculates the entered test data from a digital camera and creates an exposure profile; These profiles contain exposure characteristics for Flash, Ambient, Incident and Reflected exposure modes from ISO 3 to ISO 8000; In addition, the dynamic range at all ISOs are calculated and stored; Exposure profiles are transferred via a USB cable (included) from the Data Transfer Software (included) directly into the L-758DR. Once the data is completely transferred to the meter, it is automatically calibrated and programmed for the specific digital camera sensor or film loaded in its memory
    Dual ISO Settings
    The L-758DR offers the flexibility of taking a single measurement and displaying the f-stop and shutter speed for two different ISO film speeds, such as negative film and Polaroid proofing film; The second ISO setting is also ideal for calculating exposure compensation such as filter factors or bellows factors, without having to change the original film speed settings
    All Weather Design
    All buttons, switches and compartments are sealed and the meter housing has been constructed with durable, rugged conditions in mind; Ideal for shooting in sandy, rainy or humid conditions
    14 Custom Settings
    The custom settings mode provides a quick and easy setup of individual meter preferences. The L-758DR's features and modes can be turned on or off, as well as modified to fit the needs of the individual using the meter
    Memory All Clear
    Memorized values can be all cleared or the last memorized value can be deleted (backspace clear), in addition, individually selected values can be selected and cleared

    Sekonic L-758DR/401758 Reviews

    L-758DR DigitalMaster Flash Meter is rated 4.8 out of 5 by 162.
    Rated 5 out of 5 by from The Best I use this for portraits and weddings, and landscapes. my third light meter from sekonic and b&h. My first sekonic was the 508 zoom master and it works like new after 18 years. The 758 dr. Rocks because of it's pocketwizard trigger. you can trigger a reading at your subject. You don't need an assistant. I am a 1 man operation and use multiple pocketwizards for stunning light in outdoor weddings and portraits. The sekonic Pwizard trigger is actual more consistent than my Pwizard on top of my camera. Very accurate readings, very easy to use. Waterproof.And b&h h is awesome. I have spent probably $20k at b&h the last 6 years.

    Rated 1 out of 5 by from Beware if You Are a Mac User! After spending an hour to calibrate this meter, I discovered, at the very end of the process, that Sekonic's Data Transfer software would not recognize the meter, which was plugged into my Mac Pro running Snow Leopard. This is simply not acceptable for a pro meter. Moreover, Sekonic has no customer service. There is no number to call, and no email address that goes to customer service. Perhaps Sekonic should issue $500 rebates to those who cannot get full use out of their L-758DRs. Further, the expensive target is now useless to me. There is simply no excuse for such shoddy software and lack of customer service.

    Rated 5 out of 5 by from Best Ever I am primarily a landscape photographer however I do have a studio and do portrait work as well. The Sekonic L-758DR handles it all! The spot metering (1 degree) is invaluable when trying to pluck out crucial highlights in a landscape scene and the wireless capability to trigger Pocket Wizard receivers in the studio is awesome as well! Check out Joe Brady's webinars on this meter either on Sekonic's website or YouTube, these will get you up and running very quickly and you will have a thorough understanding of how this baby will rock your photography world!

    Rated 3 out of 5 by from Great electronics - fragile construction Great meter. Included software is less than you might expect, but you can do firmware upgrades and profile the meter to your camera. There is a big if though. You need to purchase a rather expensive target to shoot images for profiling. $$ extra. Should be included if you buy the meter. At the very least, it should be bundled at a great discount. Very expensive meter for such cheap construction. Body is plastic. Dials are plastic, too. Case barely fits, and is very cheap and not protective. This is a professional meter in hobbiest packaging. Body should be metal - magnesium alloy. Battery door should be more secure. Case should be hard and protective. Sekonic could and should do better.

    Rated 4 out of 5 by from Great meter but support issues The L-758DR is a great meter that functions well in incident and reflective modes. It's very easy to use once you get used to the the interface. It's very consistent and seems to be very accurate. I like having the ISO2 button to give me the exposure compensation settings. My only complaint is that Sekonic doesn't seem to have any interest in updating the data transfer software for OS X 10.11. El Capitan has been out for over 7 months and they have no support for it yet. Their support organization hasn't even responded to my email regarding the issue. If you want to load your camera profile into the meter and are running 10.11 it isn't possible. No connection can be established from the Mac to the meter using sub and 10.11.

    Rated 5 out of 5 by from Metering is the way to go I have relied heavily on my camera's metering and had mixed results. Now that i use this meter, I get the look I want every time with great exposure. I purchased this particular unit because it is rugged and I need to travel with it. The only problem I had with it was syncing it with the new PocketWizard FlexTT5, but the issue is really with the PW. I had to connect the PW to the computer using the supplied USB and disable the Use ControlTL on one of the configurations. It was painless, but I just expected to use it all together out of the box. Everything was setup in about 10 minutes and I am really happy with box items.

    Rated 5 out of 5 by from Excellent Meter I hesitated buying an incident meter because so many vocal digital photographers said they were obsolete. Theyre wrong. Setting ratios on studio strobes with the integrated pocket wizard module eliminates guesswork, exposures are more accurate and predictable and the workflow is more efficient. The L-758DR is well built, the Tenba case is well padded with a belt loop for easy access and includes a storage area for a backup battery. The meter & exposure profile target are expensive, but you get what you pay for. Using the L-758DR provides me with invaluable feedback in my lighting analysis: ratios, dynamic range, percentage of flash relative to ambient in an exposure, etc. You will learn more about lighting by actively metering the scene and observing meter readings than by passively letting the camera do it.

    Rated 4 out of 5 by from high quality product, low quality manual I have some experience with meters and this certainly seems top knotch. It's well constructed and has more options than I can imagine using. However, many options are not very easy to figure out and the instructions are very poor. The internet has some videos that are ok, but they don't really match the manuals or downloads from the sekonic site. I figure, I'm going to have to sit and take several hours diddling with it just to get some idea how many features work. I'm going to try to do my camera calibration. It's probably easier than what appears by the instructions, but i'll see.

    Will this light meter communicate with an Elinchrome BRX 500 monolight purchased in the US from BH Photo?
    Asked by: David G.
    The L-758DR has a PocketWizard trigger built in. If any Plus-Series, MultiMAX, or FlexTT5 is connected to your flash, you can trigger the flash from the meter by simply pressing the measuring button. As it transmits on a different frequency from the Elinchrom flashes, it cannot trigger the built in receivers.

    Can anyone please let me know a suitable vertical pouch for this meter ? The provided horizontal one occupies too much space in my belt and it is very diffcult to take the meter in and out of the pouch with one hand.
    Asked by: Shree L.
    Sekonic does not have a vertical case for the L-758 but is considering it. I am sure there are utility cases in the market that will fit it but do not know of any. Wish I could be of more help.

    I understand this meter can trigger Pocketwizards. But after looking on Sekonic's website and reading the manual, it's not clear if the Pocketwizards output can be changed from the meter like it can with the L-458DR. Can the PW's output be changed from the L758DR? Will this meter do what the PW AC3 zone controller does, essentially replacing it?
