Sekonic L-758DR DigitalMaster - Sekonic L-758DR DIGITALMASTER

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. It offers features such as Spot/Incident measurement
modes, flash or ambient measurements, flash analyzing, PocketWizard wireless triggering built-in, PLUS Exposure Profiling, Pre-Exposure warning,
14 selectable custom settings and much more. 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.
