"The pocket-sized Sekonic L-308S 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. 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. 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. Incident or reflected light measurement - Reflected light readings are captured at a receiving angle of about 40 degrees for subject readings made at the camera. Slide the L-308S's built-in Lumisphere over the silicon photo diode for incident light exposure readings of three-dimensional subjects. Snap on the included Lumidisc over the sensor for metering flat artwork or measuring contrast and/or exposure ratios within a scene. Ambient / Flash measurement - Incident or reflected ambient light readings can be made with the L-308S over a wide range of lighting conditions at shutter speeds from 60 seconds to 1/8000th of a second and apertures from f/stops of f/1.4 to f/90.9. Flash at speeds from 1 to 1/500th of a second can be measured cordlessly or wired using a separate accessory PC cord. Flash and ambient readings are automatically calculated to display the proper exposure for the combination. Accurate measurements - Exposures accurate down to a tenth-of-a-stop for both ambient and electronic flash light readings are available in full-stop mode. The L-308S can also display shutter speeds and apertures in half or third-stop increments to mirror the exposure settings on your camera with a repeat accuracy of +/- 0.1 EV. For cinema applications frame rates can be set from 8 to 128 frames per second. ISO sensitivity can be set from 3 to 8000 in third-stop increments. Compact size and lightweight - The L-308S is the smallest digital flash meter for reflective and incident light readings in ambient or electronic flash lighting conditions. It is compact and light enough to fit into a shirt pocket, yet versatile enough to meet virtually every photographic demand. The L-308S is powered by a single AA battery and weighs only 3.4 ounces (95g). Its measurements are a compact 2.5""W x 4.3""H x 0.9""D (63mmW x 110mmH x 22mmD). Accessories - The Sekonic L-308S 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, and is backed by our outstanding customer support team.
