A legacy of accuracy pocket-sized and exceptionally accurate, the Flashmate L-308X-U light meter from Sekonic is a compact tool for metering both ambient and flash lighting as well as working in video with dedicated Cine and HD Cine modes. Equipped with a sliding lumisphere, the L-308X-U is able to measure ambient light as well as reflected light via a lens with a 40° reception angle. This meter also has a wide metering range; from 0 to 19.9 EV at ISO 100, and can work with flash within a range of f/1.0 to f/90.9 at ISO 100. Repeat accuracy is also important when metering, which the L-308X-U delivers with a rating of <0.1 EV on repeat exposures.  Maximum versatility last year, Sekonic introduced their groundbreaking flag ship light meter, the Speedmaster L-858D-U. By merging functionality for both photography and cinematography into one light meter, Sekonic created a powerful and invaluable tool for image makers of every kind. Now Sekonic is bringing that philosophy to the immensely popular L-308 series with the new Flashmate L-308X-U.
