  • Sekonic Flashmate L-308X Light Meter


    The L-308X delivers accurate exposure readings in full-, half-, or third-stop increments to mirror the exposure displays of most popular cameras. When set to full-stop mode, exposures are displayed in tenth-stop increments with a repeat accuracy of +/- 0.1 EV.

    Proven Performance

    A legacy of accuracy pocket-sized and exceptionally accurate, the Flashmate L-308X 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.

    Fully Featured

    Equipped with a sliding lumisphere, the L-308X 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.

    Design Taken from the L-358D-U

    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.

        A Little Beauty That Serves The Purpose.

        Not knowing the difference, the previous year I bought a minty 20-yr-old L-308. It functions only with shutter priority, doesn’t retain measured data when powered off, and doesn’t display ISO unless one presses the “ISO” button.

        The “X” model remedies all that, meters 1EV dimmer light, can be operated shutter or aperture-priority, has an automatically backlit screen, and can be set to meter in 1/2 or 1/3 stops. Plus it can be custom-calibrated if you prefer.

        Mostly, I’m working on a tripod in Aperture Priority. This alone lead me to buy the current model. Shutter priority doesn’t cut it when I’m doing weirdscapes with long focal-length medium-format lenses.

        When I make a reading in aperture-priority mode, another, smaller digit appears right next to the f/#… it’s the tenth of an f/stop — to nail the exposure to that level of precision.

        High points cont’d: Fast, free shipping to Victoria, BC, a 2-yr. Strobe Pro warranty and (at time of purchase) the lowest price anywhere in Canada (from my research). I meter incident light. It’s great to have 100% confidence in my meter. One of the best features of this little varmit: a low cognitive load when out shooting. This frees up brain-power to find and frame interesting compositions. Altogether this bad boy is a “W” for me.

        Low point: not inexpensive. (High point: Not cheap either!)
