Overview

Items Include:

L-308S Case, AA 1.5 volt battery, Strap, Syncro Terminal Cap and Lumidisc w/ case

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.

Exposure data is displayed on the LCD screen, which has been redesigned to emulate the look and feel of the LCD on the ‘bigger-brother' Sekonic L-358 flash meter. Exposure data and related information is displayed using large type and easy-to-read icons. At ISO 100 ambient light can be read over an EV range of 0 to 19.9 in both incident and reflected mode. Flash exposures are displayed from f/1.4 to f/90.9 (or about f/124). ISO sensitivity is set from 3 to 8000 in third-stop increments. For cinema applications, the L-308S can be programmed to display exposure times from 8 to 128 frames-per-second.

The Sekonic L-308S FLASHMATE comes with a Lumidisc (with pouch), a soft case, strap, synchro terminal cap and a AA battery.

Features

Pocket-sized Digital Meter for Incident and Reflected Flash and Ambient Light Readings

  • Smallest digital flash-meter for reflective and incident light readings in ambient or electronic flash lighting conditions
  • Exposures accurate down to a tenth-of-a-stop for both ambient and electronic flash light readings in full-stop mode. Meter 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
  • At ISO 100, the ambient EV range is 0 to 19.9, flash f/stops range from f/1.4 to f/90.9 with a shutter-speed span of 60-seconds to 1/8000th-of-a-second (1 sec to 1/500th for flash). 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
  • Pocket-sized, and easy to stow away. The L-308S measures 2.5"W x 4.3"H x 0.9"D (63mmW x 110mmH x 22mmD), and weighs in at 3.4 ounces (95g).
  • Includes Lumidisc with pouch, soft case, strap, synchro terminal cap, AA battery.
  • 1-Year Warranty, extendable at no charge to 3 years total (USA only) after registration, backed by our outstanding customer support team
