## Summary description

Sekonic L-858D Speedmaster is a professional light meter for photographers and cinematographers. It features a dual-display layout and supports wireless triggering for off-camera flash control. Designed to measure ambient and flash exposure, it helps set accurate shutter, aperture and ISO values, streamline studio and location workflows, and improve exposure consistency for stills and motion projects.

## Long description

The Sekonic L-858D Speedmaster is a professional light meter designed for photographers and cinematographers who require precise ambient and flash exposure measurements. The instrument combines a dual-display layout with advanced metering modes to provide quick access to incident, reflected and flash readings. Built to measure shutter, aperture and ISO relationships and to support wireless triggering, the L-858D streamlines workflow in both studio and location environments while maintaining consistent exposure across stills and motion projects.
Advantages
The dual-display layout presents key exposure information simultaneously, reducing the need to toggle between modes. Integrated flash metering and wireless triggering capability enable remote control of compatible strobes for repeatable flash ratios and TTL calibration. A wide range of metering functions and high-precision sensor design deliver reliable measurements for ambient, continuous and flash lighting. Compact, ergonomically arranged controls and a clear readout support efficient operation during fast-paced shoots.
Suitable for
Studio photography with multiple flash units
Location shoots requiring quick ambient and flash measurements
Cinematography and video lighting setups
Exposure verification for product, portrait and commercial work
Fine-tuning TTL flash systems and manual flash ratios
Key specifications

How to use
Hold the meter at the subject position and select the appropriate metering mode for incident or reflected measurements. For incident metering, position the meter’s diffuser toward the main light source; for reflected metering, point the meter toward the subject from the camera position. Use the dual-display to read shutter, aperture and ISO relationships directly, and switch to flash mode to take pre-flash or manual flash readings. When using wireless triggering, pair the meter with compatible strobes following the manufacturer’s linking procedure, then trigger test flashes to set ratios or TTL compensation. Adjust camera settings based on the displayed exposure values and confirm with test frames or meter re-checks.
Usage recommendations
For consistent results, perform incident and reflected checks when lighting or subject position changes. Use the dual-display to compare ambient and flash contributions and set desired flash ratios. When working with mixed lighting, verify color-temperature balance with appropriate tools and re-check exposure after any significant change in scene brightness or lighting setup.
