Sekonic L-308X-U Flashmate

The Sekonic L-308X-U Flashmate is a compact and highly accurate exposure meter designed for photographers and filmmakers, offering precise ambient and flash light measurement with dedicated photo, HD Cine, and Cine modes.

The Sekonic L-308X-U Flashmate is a professional-grade exposure meter built for photographers, videographers, and cinematographers who require precise and consistent light measurement in any environment. Compact and lightweight, it delivers exceptional accuracy for both ambient and flash lighting, making it ideal for studio and on-location work.

Equipped with a sliding lumisphere, the L-308X-U can measure incident light as well as reflected light with a 40° angle of view, offering flexibility for different shooting scenarios. Its wide measurement range—from 0 to 19.9 EV at ISO 100 and flash measurements from f/1.0 to f/90.9—ensures reliable results across various lighting conditions. With repeatability rated at less than 0.1 EV, users can trust consistent exposure readings every time.

The device features multiple shooting modes, including photo mode with shutter and aperture priority, as well as dedicated HD Cine and Cine modes for video production. Cinematographers can select frame rates and shutter angles while benefiting from precise exposure control down to one-tenth of a stop. Support for ISO 850 makes it especially useful for modern digital cinema cameras.

Additionally, the L-308X-U provides readings in lux (lx) and footcandles (fc), allowing for quick and accurate lighting adjustments. Its intuitive interface and clear display make it easy to use, even in fast-paced production environments.
