The Sekonic L-308 series of light meters was introduced in 1992.
It is designed as a compact, easy-to-use electronic ambient and flash meter with a LCD screen. Incident and reflective measurement can be accomplished by sliding the Lumisphere. Cover the lens for incident mode and uncover for reflective mode. It is a shutter priority meter. This means you select the shutter speed and the meter calculates your aperture setting. When this is accomplished, pressing the up and down buttons on the side of the meter shows the corresponding shutter and aperture settings for the proper exposure. There is no aperture priority mode on this meter.
Flash meter reading can be accomplished by attaching a PC style sync cord, the meters measure button can be used to fire off the flash. A non-corded wireless mode is also available, but requires manually firing the flash.
Additionally there is an EV mode, as well as a cine mode that displays frames per second. To use the fps cine mode requires the meter to scroll past the shutter speeds of 1/8000s.
The L-308 Flashmate is the original model followed by minor revisions L-308B in 1994 and L-308B II in 1996. The B models have improved sensitivity and can measure down to 0EV.
