With it's 2.7" colour touch screen and truly innovative and sophisticated features, the Sekonic Speedmaster L-858D leads the way to the next generation of light measurement control as the world's first multi-function light meter for photographers and filmmakers. The first meter of its kind capable of measuring flash duration, while also being able to achieve an accurate ambient exposure reading in dimly lit scenes as low as 0.1 lx, the Sekonic L-858d provides image-makers of all levels with the critical exposure data they need to create stunning and beautiful imagery.  The first to provide wireless compatibility with Elinchrom, Phottix, and PocketWizard products, the Sekonic Speedmaster L-858D also provides ultimate control to photographers seeking a faster and more streamlined workflow. Limitless creative possibilities are within reach through the meter's ability to measure High Speed Sync (HSS) and calculate proper ambient-flash exposure for precision flash exposure control.
