Sekonic L-308B Flashmeter

It is designed as a small compact easy to use basic 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.
