Sekonic L-858D-U Speedmaster Light Meter (401-858)

Designed for professional photographers and filmmakers, the Sekonic L-858D-U Speedmaster combines over 60 years of precision engineering with cutting-edge technology. As the world’s first multi-function light meter to measure flash duration, it delivers the critical data needed for perfect exposure—whether you are working with High-Speed Sync (HSS), ambient-flash balance, or cine settings.

Built for modern workflow demands, the L-858D-U provides incredibly accurate readings in extremely low light, measuring down to 0.1 lx to match high-ISO cameras. A highly intuitive 2.7" color touchscreen ensures quick adjustments, while built-in wireless compatibility with Elinchrom, Phottix, and PocketWizard systems allows for seamless cordless flash triggering in the studio or on location.
