Sekonic L-758DR DigitalMaster Flash Meter - For Ambient and Flash Light with Radio Triggering

World's first Multi-function Light Meter with Exposure Profiling and Wireless Triggering - DIGITALMASTER L-758D/L-758DR

The DIGITALMASTER L-758 series was designed from its inception to offer today's digital and film shooter with repeatable precision, accurate measurement and digital exposure control that is necessary for today's photographer. It offers cutting edge features never before available in any light meter and redefines what a light meter is and why it's a critical tool for digital exposure control.

Main Features

Exposure Profiling
Up to three digital camera exposure profiles can be stored and recalled. Once selected, the L-758 series can recall an exposure profile (from a digital camera or film) and display the dynamic range and clipping point on the aperture scale or EV scale. Any compensation value that is required to match the camera sensitivity is loaded into the appropriate measuring mode and automatically applied to all measurements.
L-758 can compensate and be calibrated to the sensitivity of your D-SLR, digital back or favorite film. Exposure latitude warning indicator, alert the photographers when the lighting situation is exceeding the dynamic range of the camera or film before the image is captured.

To ensure repeatable accurate and consistent results for tonal range and digital exposure or film control, put the power of control in the palm of your hand, DIGITALMASTER.

Data Transfer Software
The L-758 series light meters have a USB port built-in to connect the light meter to a computer (Windows or MAC) with a USB cable. Exposure Profile Data is exchanged between the computer and the light meter using the Data Transfer Software, which enable the photographer to input the calibration compensation data directly in to the light meters programmable memory chip.

Data Transfer Software and Software Guide (Testing procedure, Image analyzing and Data entry) are preliminaly for still photography use.

Up to nine measured values can be memorized in both incident and reflected modes independently or combined
L-758 series can memorize measured values in both incident and reflected modes independently or combined. When the memorized values are combined it is possible to take a mid-tone measurement using the Lumisphere in incident mode, than take a spot highlight, and shadow measurement by simply switching to reflected measuring mode.

Highlight and shadow tones can be measured and quickly viewed to determine if there are within the Dynamic range or Clipping points of the digital camera or type of film being used. In addition, the Mid.Tone value can be shifting to adjust the highlight or shadow to be within the range required.

1 Degree Spot with Digital Display
The rectangular 1º spot viewfinder displays f-stops, shutter speed, percentage of flash and much more with an EL (Electronic-Luminescent) digital display.

It can instantly be switched from incident to spot measurement mode. With its super sensitive sensor, the L-758 series can measure the reflected flash output down to an amazing f/2.0 and ambient measurements as low as EV1.

Flash Analyzing Function
The ambient light, flash light and total amount of light are each displayed on the analog scale, and the ratio of flash light to the total amount of light is displayed at that time as a value in 10 % steps. Now you can take ambient, flash or mixed lighting exposure measurements without fumbling with meter modes, switches or different displays.

Flash Radio Trigger Function with Wireless Radio Transmitter Module
With the radio transmitter module plugged into the meters radio compartment and a receiver (PocketWizard® products; Plus, Plus ll or MultiMax receivers/transceivers) connected to one or more electronic flash units, the meter provides a convenient system that enables one person working alone to measure flash output without the need of a sync cord. Pressing the measuring button simultaneously triggers the flash and measures the light.

L-758DR has a built-in transmitter module, and L-758D has optional transmitter module.
(Only CE version of L-758D is available)
NOTE:
The Wireless flash triggering system may be used only in countries where a permit for the control frequency has been issued by the government office in charge. There are several kinds of frequencies in the world, and we recommend you check if your transmitter(s) and receiver(s) are compatible each other.

Full, 1/2 or 1/3 Step Selectable Readings
Both shutter speeds and apertures can be displayed in full, 1/2 or 1/3 step increments to accommodate most camera manufacturer's settings.

Auto Backlight
Electro-Luminescent Display lights up automatically in low light. (6EV or less)

Step Up Ring (Lens Hood)
The step up ring makes it possible to attach different diameter filters using the appropriate step-up adapters in front of the 1º spot lens (up to 40.5mm filter thread). It also acts as a lens hood preventing erroneous light measurement caused by lens glare and flare.

All-Weather Design
This meter has an All-whether design to endure rugged outdoor condition.
(JIS standard water resistance class 4)

Retractable Lumisphere
You can select extended lumisphere (for 3-D object) or retracted lumisphere (for flat object) at one touch of a rotating the lumisphere retracting ring. Extended Lumisphere

Custom Setting
The Custom Setting mode provides a quick and easy setup of individual meter preferences.
L-758DR/D have14 settings and the L-758CINE has 17settings.
