About the Sekonic L-358

The Sekonic L-358 Flash Master is an advanced, yet easy to operate, exposure analyzing light meter, that incorporates the latest technology in handheld meters. The L-358 features a retractable incident Lumisphere for standard or cosine corrected light readings, provides both hemispherical and narrow angle readings. Measurements can be taken in either incident or flash metering modes with accurate and convenient flash and ambient analyzing.

In all electronic flash measurements, an analyzing feature simultaneously evaluates both flash and ambient light and displays the values in three ways: a) combined readings of flash and ambient, b) percentage of flash in the total exposure or c) simultaneous display of flash, ambient and combined readings on the analog scale. An easy-to-read illuminated LCD panel directly displays full, 1/2 or 1/3-stop shutter speeds or apertures and exposure/calibration compensation. Selecting settings is quick and easy with the built-in Jog wheel and cine shutter speeds up to 360 frames per second makes the L-358 a versatile tool in the most demanding lighting scenario. Optional spot finders extend the versatility of the meter with a choice of 1, 5 or 10 degree measuring angles with a viewable parallax-free viewfinder.

The L-358 Sekonic Flash Master incorporates the world's first optional internal Digital Radio Transmitter Module compatible with Sekonic and PocketWizard Digital Radio Receivers, which eliminates the need for an additional external transmitter at the meters position.
