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 2.522W x 4.322H x 0.922D (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.
