Sekonic L-858D-U Speedmaster Light Meter with RT-EL/PX Transmitter Module, Incident & 1∞ Spot Meter with Flash Duration Analysis & Elinchrom/Phottix Wireless Control Bundle

Sekonic L-858D-U Speedmaster with RT-EL/PX Transmitter Module is a professional bundle combining advanced exposure measurement with integrated Elinchrom Skyport and Phottix wireless flash control. The L-858D-U features incident ambient and flash metering along with a built-in 1∞ reflected spot viewfinder, enabling precise highlight and shadow evaluation for accurate exposure control. Engineered to measure flash duration including brief HSS bursts, it provides critical t.1 and t.5 data for motion freezing and high-speed sync applications. With a measuring range of -5 to 22.9 EV at ISO 100, it performs reliably across diverse lighting environments. The included RT-EL/PX transmitter module installs internally and enables direct flash triggering, remote power adjustment, and compatible modeling lamp ON/OFF control for supported Elinchrom and Phottix systems. By combining metering and wireless control in one device, this bundle streamlines workflow efficiency in studio and on-location productions. Supplied with start-up guide, lens cap, strap, soft case, anti-glare film, and transmitter module, it supports demanding professional applications requiring precision and repeatable lighting control.
