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.
