The L-758 Series are the world's first multi-function light meters that can be calibrated to match the sensitivity of a digital camera's sensor at all ISO settings, flash/ambient or file format characteristics. In addition, the camera sensor's dynamic range can also be set and stored for later recall and display. Using the USB transfer cable and Sekonic "Data Transfer Software", all camera exposure profile data is uploaded from a PC or Mac computer to the L-758DR. Up to three different camera exposure profiles can be stored and quickly recalled when switching from one camera to another. With its exposure latitude warning indicators and adjustable Mid-Tone settings, the L-758 Series puts the power of optimum image tonality and exposure control in the palm of your hands. Now includes RT-CTL32 module for compatibity with the PocketWizard ControlTL system.

Reflected Light Spot Metering
The Sekonic L-758DR incorporates a precise 1-degree, reflected light spot meter. Reflected light metering tells you about the subject. Different from incident light metering that produces readings only for the middle of your camera’s exposure range, reflected light metering can also show you where the edges are. The key to working with the L-758DR’s spot meter is knowing the dynamic range of your camera. That is, the tonal range your camera is capable of recording. Program this into the L-758DR and you can easily know which details will be properly imaged and which will be over or under the range of your camera. Armed with this knowledge, you can make exposure decisions that take full advantage of your camera’s imaging capabilities to produce pictures with greater tonality and clarity than you have

Incident Light Metering
Incident light readings are, in fact, the simplest and most direct way to determine exposure. And because incident meters measure the light that falls on your subject, they provide camera settings that render the image exactly the way it appears. Blacks are black. Grays are gray. Whites are white. Retracting the Sekonic L-758’s Lumisphere enables you to quickly judge the brightness of multiple light sources for fast, accurate adjustment of lighting ratios.

Digital Photography: Boundless Possibilities
Today’s High Dynamic Range (HDR) processing enables breaking through the limits to produce results never seen before. Knowing your camera’s capabilities and precise exposure readings with the L-758D will help you make right exposure settings and save you time in processing.

Determining Dynamic Range with Exposure Profile Targets (separate purchase)
Shoot with the equipment you use most. Make tests under daylight and studio lighting. Exposure Profile Target requires an 11-shot bracket (0, +/- 5EV). Exposure Profile Target II requires a 3-shot bracket (-3EV, 0,+3EV). Make a spot reading of 18% reflectance tone and incident reading in front of target and record data. Shoot the bracketed shots based on incident light measurement.

Entering Data
Download test images into computer. If shot in RAW, convert to TIFF for computation. Enter ISO, incident, and reflected light shooting data. Then select images and press OK to watch the Sekonic Data Transfer Software program graph the dynamic range of your DSLR camera. Save the data for transfer to the L-758DR.

Programming Meter
Switch OFF L-758DR. Connect it to the computer with USB cable and switch L-758DR ON. Select up to three camera profiles. Press transfer. Switch OFF L-758DR, disconnect, and switch ON to begin using.

Full information Spot Viewfinder
The 1-degree spot meter has a broad reading range from EV 1 to EV 24.4 for ambient light and measures flash down to an amazing f/2.0. Its large, bright viewfinder with diopter correction and full-information data display give you everything you need to make the right exposure decisions without having to take your eye from the eyepiece.

Memory Mode and Latitude Display
Up to nine readings can be memorized and displayed on the meter’s analog display. Once programmed, the L-758DR’s latitude display mirrors the dynamic range of your camera and is your guide to making exposure decisions that will get you the pictures you want.

Contrast Function
Use the L-758DR’s contrast function to simplify measuring the brightness range of a scene. Spot meter a mid tone or take an incident-light reading and press the AVE/?V button to create a mid tone standard. Then press the measuring button to display the brightness difference between the standard and new reading. Knowing the dynamic range of your DSLR is vital to making the best use of this important feature.

Ambient Light Metering
Take shutter-priority or aperture-priority readings from 30 minutes up to 1/8000 second and f/0.5 to f/128 and display them in full, 1/2 or 1/3 stop increments. Exposure is displayed both digitally and on an analog scale for easy readout. Settings can be changed after reading with automatic calculation to maintain the proper exposure. The extended sensitivity range, EV -2 to 22.9 (Inc) and EV 1 to 24.4 (Ref) for ISO 100, enables taking measurements over a wide range of lighting conditions.

Flash Light Metering
Shutter-priority readings of flash light can be made with a synch cord or cordlessly at shutter speeds from 30 minutes to 1/1000. The L-758DR automatically resets after each reading in cordless mode, to enable fast adjustment of flash brightness.

Built-in Radio Flash Triggering
Simply press the measuring button to wirelessly trigger flash units up to 100 feet away. The built-in transmitter offers 32 digital coded channels and Quad-Triggering Zones and is compatible with PocketWizard radio triggering systems (including ControlTL), as well as the PocketWizard Wireless Freedom partners. Learn more about Radio Triggering.

Flash Analyzing Function
The L-758DR is especially useful for on-location shooting to lighten shadows or reduce background detail. That’s because it measures ambient and flash simultaneously and automatically indicates the percentage of flash in the total exposure. You can easily adjust the ambient flash mix by turning the Jog Wheel. The digital display indicates the camera settings and an analog display shows the relationship between ambient and flash and the total exposure.

Sekonic L-758DR Functions
All controls are instantly available. Positive Jog Wheel operation and clearly marked buttons make for fast and easy handling.

Are you eligible for finance?

Applicants must be:

  • Aged 18 years or older from the application date
  • In permanent UK residence for a minimum of three years
  • Fulfil at least one of the following employment criteria:
    • In regular, permanent employment.
    • Retired from regular employment - With a minimum age of 50.
    • Not working through disability.
    • Self-employed.

Note: All applicants will be subject to a credit reference check by the lender.

Credit is subject to application and status. Warehouse Express Ltd trading as Wex Photo Video act as credit broker and not the lender. Barclays Partner Finance act as the lender.

Can I repay early? If so how?

No repayments are scheduled in the initial six-month deferral period. However, it is possible to pay off the loan, either by way of a lump sum or in smaller amounts. If the loan is fully repaid within the six-month deferral period, then no interest is payable, but a £29.00 early-settlement will be incurred. Such repayments may be made to Barclays Partner Finance by cheque, debit card or standing order. Unfortunately it is not possible to set up a direct debit within the deferral period. Further information on how to make such repayments will be set out in the loan agreement pack provided by Barclays Partner Finance.

What happens if I don't repay within the first six months (deferral period)?

Following the six month deferral period, Barclays Partner Finance will initiate a monthly direct debit payment for the remaining duration of the loan. Interest will be charged at a rate of 19.9% APR on outstanding balances (backdated to the first date of the loan). Late payment penalties and early repayment charges will apply from this point. Barclays Partner Finance will send a reminder letter approximately one month before the six month deferral period is due to elapse. Note: If you chose to spread the cost and pay monthly, interest is charged from the start of the loan, not from the start of the repayment period.

What will I receive from the finance provider (lender)?

Barclays Partner Finance will send a loan agreement pack approximately four weeks after delivery of the goods, confirming that the account has been activated and, from this point, it is possible to make repayments against the loan.
