The Sekonic L-358 Flash Master is an photographic exposure meter introduced by Sekonic in 2001.

The design of this meter is fairly rugged with a sealed housing making it water and moisture resistant, but it is not designed as a underwater meter. The LCD display is illuminated to ease readability in darker lighting conditions. Two ISO settings make it easier to use the meter for multiple cameras or formats. This model is also features a radio trigger method. With optional radio receiver (Sekonic RR4) and transmitters (Sekonic RR/RT32), you can trigger multiple flash units and get reading without an assistant or the mess of cords.
