The new Sekonic Speedmaster L-858D is the result of the combination of 60 years of Sekonic innovation and the latest technological advances in Flash measurement, aimed at meeting the needs of today's photographers and cameras. Capable of measuring the duration of a flash, which is a first for a multifunction spectrometer, the L-858D provides critical flash and needed data in the calculation of the ambient flash-light exposure. As the name suggests, the SpeedMaster L-858D also measures brief lightning of HSS Flashs (High Speed ​​Sync) for better control of exposure accuracy due to Flash. The L-858D has the fundamental characteristics of the popular L-478D as well as functions that allow photographers to overcome the limits of ISO sensitivity, the exposure time in ambient light and flash, as well as frequencies of Images (F / S) and shutter angles for videographers. Increased sensor sensitivity for incident and reflected sources in ambient light makes it possible to perform measurements even under very low illuminance conditions. In addition, the L-858D is offered with optional wireless trigger modules, now available for Elinchrom and PhotoTix, in addition to radio trip devices from the PocketWizard range. With its 2,7 '' color touch screen and really innovative and sophisticated advanced features, the L-858D creates a break to bring the light measurement control into a new dimension.
