The Sekonic Flashmate L-308X is inspired by the popular legacy of the L-308 series that began almost a quarter of a century ago. The NEW Sekonic FLASHMATE L-308X addresses significant features and functions that meet and exceed the needs of today’s Photo and Cine/Video shooters. The L-308X includes the familiar blend of compact, lightweight and intuitive design, which has made the L-308 series so popular, as well as the Cine/Video features of the affordable DigiCineMate L-308DC.

The versatility of the latest DSLR cameras has expanded the capabilities and creativity of today’s image makers. With just one camera, today’s shooters have become multi-media image makers, blending both still and moving images seamlessly, for the ultimate storytelling. Offering all the features expected from the latest generation L-308 series, the NEW FLASHMATE L-308X features an LCD backlight, Aperture priority (Photo Mode), and ISO 850 setting (for native ISO Cine Cameras). The FLASHMATE L-308X is the perfect blend of Photo/Cine features all in one lightmeter.

The FLASHMATE L-308X offers full exposure control for photographer’s on-location or in the studio. In addition to Shutter Priority Mode, the NEW Aperture Priority Mode offers the carefree depth-of-field control provided on most DSLR’s.
