Sekonic SpeedMaster Pro L-858D

The World's First Multi-Function Light Meter with Flash Duration & Multi-Brand Wireless Triggering

The NEW Sekonic SpeedMaster L-858D combines over 60 years of Sekonic innovation with cut- ting-edge, flash-measurement technology to meet the needs of today’s photographers as well as motion image makers. Incorporating flash duration measurement, the first time in a multi-function light meter, the L-858D provides the critical flash data needed to calculate proper ambient-flash exposure. As its name implies, the SpeedMaster L-858D also measures the brief flash bursts of HSS (High Speed Sync) for precision flash exposure control.

The L-858D includes the essence of the popular L-478D series features and functions that enables photographers to break through the boundaries of ISO sensitivity, flash and ambient shutter speeds, as well as frame rates (f/s) and shutter angles for cinematographers.

Increased sensitivity for both incident and reflected-spot sensors in ambient light allows extreme low light level measurements. In addition, the L-858D offers an optional wireless triggering modules now available for Elinchrom, Phottix in addition to PocketWizard brand radio triggering devices. With its 2.7" color touch screen and truly innovative advanced and sophisticated features, the L-858D breaks away towards the next generation of light measurement control.

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.

HSS Measurements

Measuring the stroboscopic bursts of HSS flash to determine accurate flash ex- posure 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.

Optional Radio Transmitter now for Elinchrom, Phottix as well as PocketWizard*

After years of successful development and market popularity with the PocketWizard radio triggering system, 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, modeling light, camera triggering and much more.

Exposure Profiling

Because every digital camera, lens, and software is unique in its capability to capture and process light, each can produce differences in the tonal range (dynamic range) and exposure of an image. Knowing the limits of your camera’s capabilities enables making better exposures with less post-processing, and ensures your'll get what you see. 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.
