Sekonic L-398A Studio Deluxe III

The Sekonic L-398A Studio Deluxe III is a classic analog exposure meter designed for precise incident light measurement, featuring battery-free operation and a versatile Lumisphere system for both photography and cinematography.

The Sekonic L-398A Studio Deluxe III is a reliable, battery-free analog exposure meter trusted by photographers and filmmakers for accurate light measurement. Designed primarily for incident light readings, it features a 180° Lumisphere that captures light falling on three-dimensional subjects, ensuring natural and balanced exposure results. For more specific applications, the Lumisphere can be adjusted for selective readings or replaced with a Lumigrid for reflected light measurement, making it suitable for flat subjects such as artwork or scenes with high contrast.

At the core of the L-398A is an advanced amorphous photosensor, eliminating the need for batteries and ensuring consistent performance in any environment. The intuitive analog dial provides a full range of aperture and shutter speed combinations at a glance, allowing users to quickly determine optimal exposure settings. This makes it especially useful in fast-paced shooting scenarios or as a dependable backup meter.

With support for multiple metering modes—including shutter priority, aperture priority, cine (frame rate priority), and footcandle (FC) measurement—the L-398A is versatile enough for both still photography and motion picture production. Its compact and durable design, combined with a wide ISO and exposure range, makes it a practical tool for studio and on-location work.
