Sekonic Speedmaster L-858D Light Meter. Featuring a 2.7″ full color touch screen display, the L-858D also brings back exchangeable radio modules (currently available for Elinchrom, Phottix, and PocketWizard), so you won’t need a different light meter for each flash system (as the L-478D series requires).
With High Speed Sync (HSS) capability almost a must have feature now for light manufacturers in 2016, Sekonic have stepped up to produce a light meter capable of measuring flash duration data, and the brief flash bursts of HSS.
