Sekonic's compact flash and ambient meter provides great freedom combined with high precision. The Sekonic L-358 Flash Master features flash/ambient analyzing in all flash modes, and when used with an optional plug-in internal radio transmitter module (sold separately) that eliminates the need for cord connections while measuring flash up to 100 feet away (when flash units are used with compatible radio receivers).

With options such as shutter speeds and apertures selectable in 1, 1/2 or 1/3 stop increments the L-358 makes operation most efficient by matching the displayed f/stop and shutter speed values to the photographer's camera. Additional features include all weather design, nine memory banks, a retractable lumisphere, included Lumigrid attachment for reflected metering and large cool-blue electro-luminescent backlit LCD.

The slim L-358 is ideal for professional photographers, cinematographers, and dedicated enthusiasts in the studio, on location or anywhere.


Key Features

  • All-weather digital ambient and flash light meter
  • A simultaneous reading of flash and ambient light is analyzed. The readings are displayed in three different ways on the LCD:

    1. Combined readings of flash and ambient
    2. Percentage of flash in the total exposure
    3. Simultaneous display of flash, ambient and combined readings on the analog display
  • A built-in adjustable incident dome (Lumisphere) provides full measuring in the standard position or when retracted, provides cosine corrected light readings for individual light source measurements or flat artwork.
  • Optional radio transmitter connects with Wizard flash slaves
  • 9 memory banks are available in both Aperture Priority and Shutter Priority Modes, making contrast evaluation and averaging possible in both modes.
  • Both shutter speeds and apertures can be displayed in full, 1/2 or 1/3 step increments to accommodate most camera manufacturers settings.
  • Dual ISO settings possible
