For mixed lighting scenarios, the L-358 displays the combined exposure values of both flash and ambient light sources, including the percentage of flash in total exposure in 10-percent increments. Dual ISO buttons allow for quick exposure factoring when working with two differing film speeds, film and Polaroids, or other situations where comparison readings are desired.

The head of the L-358 swivels 270-degrees allowing you to "walk the set" while maintaining constant visual contact with the LCD display. An indigo, backlit LCD screen with large text and icons allows for easy referencing under all lighting conditions.

Incident readings of three-dimensional subjects are taken using the Lumisphere, which can be retracted for selective, narrower-field readings such as contrast ratios for flash lighting. For reflective readings, simply replace the Lumisphere with the Lumigrid (included), which reads the center 54-degrees of the scene. For reflected spot metering, 1, 5, and 10-degree viewfinder spot attachments are available as optional accessories. Up to nine exposure readings can be stored and tagged on the LCD's analog scale. Electronic flash exposures can be taken wirelessly or with a PC cord. Plug in the optional Sekonic RT-32 Radio Transmitter Module and you can wirelessly trigger any PocketWizard-enabled flash system within a 100' range.

The Sekonic L-358 displays an f-stop range of f/1.0 to f/90.9, and a shutter speed range of 30-minutes to 1/8000th-of-a-second (1/1000th in Flash mode), both of which can be displayed in full, half, and third-stop intervals to mirror your camera's exposure display. When set to "full", the exposure is displayed in tenth-of-a-stop increments with repeat accuracy of +/- 0.1 EV.

For motion picture applications, the L-358 calculates cine readings from 2 to 360 frames-per-second. As with all Sekonic meters, the Sekonic L-358 Flash Master includes a 3-year warranty and the best customer support you're ever likely to find.
