The pocket-sized Sekonic L-308S FLASHMATE is the smallest and lightest digital light meter in the Sekonic line-up. Designed to read ambient or flash exposures in either reflected or incident modes, the L-308S 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. Reflected readings capture at a light receiving angle of about 40-degrees, or slightly wider than the viewing field of a normal lens. For incident readings, a small, built-in Lumisphere slides over the silicon diode sensor. For flat-field incident readings, a Lumidisc (included) snaps over the sensor for metering flat artwork or measuring contrast and/or exposure ratios within a scene. Electronic flash exposures can be taken with or without a PC cord.
