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.

I have a question about the product Sekonic L-858D Speedmaster Light Meter

Two-Year Warranty for Business and Retail Customers

We stand behind the quality of our products, which is why FOMEI provides a two-year warranty (24 months) on this product from the date of purchase, fully valid for both individuals and business customers purchasing under their business ID.

Any defects are handled directly in Hradec Králové, where we operate a fully equipped professional electronics service center with a team of trained technicians ensuring fast and high-quality repairs.

Our technical center has an extensive stock of spare parts, so repairs are normally carried out quickly without delays. We understand the situation of professionals for whom photographic equipment is a main source of income, which is why we offer the possibility of lending an equivalent replacement product for the entire duration of warranty repairs.

Consumable Material

If the package or delivery includes consumables (e.g., bulb, tube, flash tube, battery), their lifespan is indicated on the product, packaging, manual, or warranty card. If not specified, the lifespan is 6 months.

Post-Warranty Service

Our products do not end their life when the warranty expires. Thanks to the quality of parts and supplier stability, our flashes have typical repairability for more than 10 years from the date of sale. Most defects are repaired rather than simply replaced. We handle both electronic and physical damage.
