Description:

Spot & Incident Light Readings Under Flash and/or Ambient Lighting Conditions Calibrated
to match the Sensitivity of Your Camera's Imaging Sensor

The Sekonic L-758DR DigitalMaster is simply the most dynamic light meter you will ever
own. It can record incident or 1-degree spot-readings under ambient and/or strobe lighting
down to a tenth-stop in accuracy, and it's sealed against the nastiest of weather. With the
included Sekonic RT-32 Radio Transmitter Module and you can wirelessly trigger
PocketWizard-enabled flash systems within a 100' range. But that's not what makes the
Sekonic L-758DR DigitalMaster different from any other meter you have owned. What
moves the L-758DR DigitalMaster to the head of the class is that it is the only meter that
can be calibrated to read light the way the sensor in your particular camerareads light.

Like film, imaging sensors vary in light sensitivity levels from one batch to the next. Despite
manufacturers best efforts, fluctuations of native ISO sensitivities of up to plus/minus half-a-
stop can be detected across the uncut wafers as they come off the manufacturing line.
Depending on which 'slice of the pie' is inside your camera, the specs listed in the camera
manual may not hold true to the characteristics of the sensor in your particular camera.

By running an easy calibration test using Sekonic's L-758DR, a Sekonic Exposure Profile
Target (optional) and the included Data Transfer Software (Mac & Windows), you can
accurately profile the sensitivity characteristics of your camera's sensor to determine the
compensation value for its true native ISO, dynamic range and clipping points.

Features:

• Profiles the specific sensitivity levels of your camera's imaging sensor for exacting light
  readings.
  
  
• Exposures accurate down to a tenth-of-a-stop in full-stop mode for both ambient and
  electronic flash light readings with a repeat accuracy of +/- 0.1 EV. Meter can also
  display shutter-speeds and apertures in half or third-stop increments to mirror the
  exposure settings on your camera. Flash exposures can be recorded cumulatively or
  non-cumulatively.
  
  
• Built-in 1-degree spot meter features an adjustable diopter (-2.5 to 1.0d), and is
  threaded for 30.5mm filters and/or lens hood (a tethered lens cap is included). Large
  red LED characters display exposure data within the viewfinder allowing for real-time
  exposure referencing while maintaining continuous eye contact with your subject.
  
  
• The L-758DR's head swivels 270-degrees allowing you to æwalk the set' while
  maintaining constant visual contact with the meter's LCD display. Flash exposures
  can be taken with or without a tethered PC cord.
  
  
• Up to 9 readings can be stored for meter averaging and contrast evaluations in
  aperture and shutter priority modes. Mid-tone button allows you to shift the highlights
  or shadows to within the dynamic range of the profiled exposure reading. Warning
  flashes for out of range readings.
  
  
• Incident readings of three-dimensional objects are taken using the Lumisphere, which
  can be retracted for selective, narrower-field readings such as contrast ratio for flash
  lighting or for flat-field objects such as artwork.
  
  
• For mixed lighting scenarios, the Sekonic L-758DR DigitalMaster displays the
  combined exposure values of both flash and ambient light sources, including the
  percentage of flash in total exposure in 10-percent increments.
  
  
• Dual ISO buttons allow for quick exposure referencing when working with two
  differing film speeds, film and Polaroids, or other shooting scenarios involving dual
  ISO ratings.
  
  
• An indigo, backlit LCD screen with large text and icons allows for easy referencing
  when ambient light levels drop below EV 6.
  
  
• For wireless metering û including Selective Quad Triggering - the included Sekonic
  RT-32 Radio Transmitter Module will wirelessly trigger PocketWizard-enabled flash
  systems within a 100' range from a choice of 32 channels.
  
  
• Includes soft case, strap, synchro terminal cap, lens cap, Data Transfer Software, neck
  cord, CR123A lithium battery, custom function and multi-function charts (stickers).
  
  
• 1-Year Warranty, extendable at no charge to 3 years total (USA only) after
  registration, backed by our outstanding customer support team.
