Sekonic L-858D Speedmaster Light Meter

Sekonic L-858D Speedmaster Light Meter

Sekonic Speedmaster L-858D is the world’s first multi-function, multi-brand wireless triggering light meter. It is the first of its kind capable of measuring flash duration and brief flash bursts like you find from HSS (High Speed Sync) for precision flash control.

Retractable Lumisphere & 1° Spot
The Sekonic L-858D-U has a retractable lumisphere that enables you to measure both flat and 3 dimensional objects. The 1° spot is perfect for landscape photographers and measuring the contrast of any scene.

Measure Flash Duration
The first fully functional exposure meter to measure flash duration. Now know if your flash will freeze your subject.

Up to 3 Stops Increased Light Sensitivity
Accurately meter scenes lit by candlelight or get the right measurement for long-exposure night photography.
