The Sekonic L-308X-U Flashmate Light Meter is the perfect solution for both accurate and portable light measurement. The L-308X takes accurate measurements of both ambient and reflected light using its sliding lumisphere, with a lens with a 40 degree reception angle. The metering range is very wide; from 0 to 19.9 EV at ISO 100. The meter can also work with flash within f/1.0 to f/90.9 at ISO 100. The Sekonic light meter delivers high repeat accuracy with a <0.1 EV rating on repeat exposures.
The Flashmate L-308X-U combines functionality for both photography and cinematography into one light meter. Image makers of every kind will find the Sekonic L-308X-U to be a powerful and invaluable tool for their profession or hobby.
Three Meters in One
The Sekonic L-308X-U features 3 meters in one, with three metering modes.
The Photo Mode gives photographers full exposure control wherever they might be, be it on location or in the studio. The screen clearly displays measurement data for flash and ambient light readings, including ambient EV measurement. The new Aperture Priority Mode, in addition to Shutter Priority mode, allows photographers to take easy measurements where depth-of-field is critical.
The HD Cine Mode allows cinematographers to quickly scout locations and is quick solution on set, too. Select from a range of frame rates and shutter angles with the 308X-U, taking accurate measurements to within one-tenth of a stop. Take measurements in the native ISOs of many of today’s professional cinema cameras with ISO 850.
The Cine Mode gives you the ability to take on the challenge of digital cinematography - it's designed with the professional in mind. You can achieve necessary exposure control with one-tenth stop accuracy by selecting the right combination of frame rates and shutter angles. The FLASHMATE L-308X offers Lux (lx) and foot-candle (fc) readout enabling you to quickly set lighting compactly, affordably, and with an easy-to-use design.
Three Ways to Measure
Take incident light readings for nearly foolproof exposure readings with the Lumisphere to quickly get the scene lit. The Lumidisc is perfect for lighting green screens, adjusting ratios and taking lux and foot-candle measurements. Reflected light readings enable measuring the brightness for subject tones, gray cards, light sources or window light.
Other valuable features include:
- Updated Available ISOs: Now includes ISO 850 the native ISO of some of today's most popular video cameras.
- Illuminated Display: Backlight LCD turns on automatically under EV5.
- Calibration Compensation: Adjust the L-308X-U to your Film or Digital camera’s exposure or matching the L-308X to other hand-held meters. (+/-1.0EV in 0.1 step)
- Custom Setting: Three custom settings are available to select display mode, increment of measurement and unit of illuminance (lx or fc) to fit to your camera and metering requirements.
- Illuminance Measurement: Lux(lx) and foot-candle(fc) display is especially used for cinematogaraphy, theatrical and other applications that require precise control of light source brightness. Either no display, lux or foot-candle is selectable in custom setting.
