Sekonic now offers optional radio trigging modules for L-858D to control Elinchrom EL-Skyport system and the Phottix Strato/II protocol products. Triggering features range from basic flash triggering to multi-zone and channel triggering, power control, modelling light, camera triggering and much more.
Sekonic’s pioneering Data Transfer Software allows quick dynamic range mapping and camera/meter calibration for the most precise control of light. Create and store up to ten camera exposure profiles with Sekonic, X-Rite or Datacolor brand calibration targets.
Flash Duration Measurements
Measuring the flash duration or “burn time” of a flash exposure has always been a critical part of any fast moving subject such as sports, fashion, wildlife, and special effect flash photographs. Unfortunately, flash duration meters have always expensive, complicated and additional piece of gear to carry, until now. The SpeedMaster L-858D’s extremely responsive system offers selectable flash duration measurements from t=0.1 to 0.9. Setting flashes to yield the fastest, or the slowest, is now quick, precise and easy.
Measuring the stroboscopic bursts of HSS flash to determine accurate flash exposure has always been considered impossible with the traditional meters. The L-858D’s highly responsive measuring system, monitoring the level of HSS output, is a game changer for HSS shooters, especially when shooting with multiple HSS flash units.
