The Sekonic L-308S Flashmate light meter is affordable and lightweight, with the latest components and precise calibration for accurate digital exposures. It offers 3 selectable aperture settings, and measures ambient or flash exposure either by incident or reflective metering modes. The redesigned LCD panel has been improved for better readability.

Key Features: Sekonic L-308S Flashmate Light Meter

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 (W x H x D) are a compact 63mm x 110mm x 22mm (2.5" x 4.3" x 0.9").
