The pocket-sized Sekonic L-308S-U Flashmate is the smallest and lightest digital light meter in the Sekonic line-up. It is designed to read ambient or flash exposures in either reflected or incident modes, and it displays accurate exposure readings in full, half, or third-stop increments to mirror the exposure settings of today's DSLR and film cameras. When set to full-stop mode, exposures are displayed in tenth-stop increments with a repeat accuracy of +/- 0.1 EV.

The LCD screen is designed to emulate the look and feel of its bigger brother, the Sekonic L-358 flash meter. Exposure data and related information are displayed using large type and easy-to-read icons, perfectly legible in even low-level lighting conditions.

The Sekonic L-308S-U FlashMate comes with a Lumidisc (with pouch), soft case, strap, synchro terminal cap and an AA battery. It has a full, 1-year warranty, extendable at no charge to 3 years total (in the USA only) after registration.
