With it’s 2.7″ color touch screen and truly innovative and sophisticated features, the Sekonic Speedmaster L-858D-U leads the way to the next generation of light measurement control as the world’s first multi-function light meter for photographers and filmmakers. Leveraging over 60 years of experience in the image-making world with cutting-edge technology, the Sekonic Speedmaster L-858D-U has undergone a significant design change and boasts a comprehensive feature set sure to meet and exceed the demands of today’s 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-U 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-U 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.
With an increased light-sensitivity and extended ISO and Shutter Speed Ranges, the Sekonic Speedmaster L-858D-U enables all image-makers to obtain measurements in extremely low light and turn those readings into creative decisions. Finally, matching the high-ISO capabilities of today’s cameras, by accurately metering in low-light, is finally possible.
