Pocket-sized and exceptionally accurate, the L-308S-U Flashmate Light Meter from Sekonic is a compact tool for metering both ambient and flash lighting. Equipped with a sliding lumisphere, as well as a lumidisc attachment for flat surfaces, the L-308S 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 light within a range of f/1.4 to f/90.9 at ISO 100. Video and film shooters can rejoice as well, with the inclusion of multiple frame rates from 8-128 fps and a 180° shutter angle.

Repeat accuracy is important with metering, and the L-308S delivers with a rating of <0.1 EV on repeat exposures. It also has a backlit LCD screen for easy viewing of setting and has both a PC sync terminal and a cordless flash option. Additionally, it runs on one AA battery.
