Sekonic L-858D Speedmaster Light Meter

Light Meter Sekonic L-858D

Sekonic Speedmaster L-858D is the world’s first multifunctional wireless trigger light meter. As the first of its kind, it can measure flash duration and short flash bursts, such as those used in HSS (High-Speed Synchronization), for precise flash control.

Retractable Lumisphere and 1° Spot Sensor

The Sekonic L-858D features a retractable lumisphere that allows you to measure both flat and three-dimensional subjects. The 1° spot is ideal for landscape photographers and for measuring the contrast of any scene.

Flash Duration Measurement

The first fully functional light meter capable of measuring flash duration. Now you know whether your flash will freeze the subject.

Increased Light Sensitivity by up to 3 Stops

Accurately measure candle-lit scenes or obtain proper readings for night photography with long exposures.
