The new L-858D SpeedMaster is the world's first multi-function meter with flash duration and multi-brand wireless triggering.
The SpeedMaster L-858D combines over 60 years of Sekonic innovation with cutting-edge flash-measurement technology to meet the needs of today’s photographers and motion image makers. Incorporating flash duration measurement, the first time in a multi-function light meter, the L-858D provides the critical flash data needed to calculate proper ambient-flash exposure. The L-858D also measures the brief flash bursts of HSS (High Speed Sync) for precision flash exposure control.
The L-858D includes the essence of the popular L-478D series features and functions that enables photographers to break through the boundaries of ISO sensitivity, flash and ambient shutter speeds, as well as frame rates (f/s) and shutter angles for cinematographers.
Increased sensitivity for both incident and reflected-spot sensors in ambient light allows extreme low light level measurements. The L-858D also offers an optional wireless triggering modules - available for Elinchrom, Phottix and PocketWizard radio triggering devices. With its 2.7" colour touch screen and truly innovative advanced features, the L-858D is the next generation of light measurement control.
The Sekonic L-858D SpeedMaster comes with case, strap, anti-glare film, lens cap, lumisphere and start-up guide.
