The Sekonic L-358 Flash Master has the perfect blend of advanced features, user-friendly functions and affordability combined in one light meter. It is both an ambient meter and a flash meter joined together in rugged, compact, all-weather housing. It features flash and ambient analysing, so you can select the right amount of either ambient or flash exposure. It also offers a built-in, retractable, incident Lumisphere, for quick comparisons of wide to narrow angle incident measurements. The Sekonic L-358 offers simplicity in the most demanding shooting situations. It's also the world's first affordable meter with Digital Wireless Freedom: With an optional digital radio flash triggering module, you now can simultaneously trigger your remote camera and/or electronic flash units and measure the flash output wirelessly without troublesome PC-synch cords. An optional, parallax-free spot finder extends the versatility of the meter with a choice of 1°, 5° or 10° viewfinders. 5 Year Warranty.

Incident Light Metering
Unlike in-camera metering, handheld, incident light metersdon’t require multi-patterned readings, complex exposurecontrol systems, or +/- exposure correction when they fail.They are, in fact, the simplest and most direct way to determineexposure. And because incident meters measure the light thatfalls on your subject, they provide camera settings that renderthe image exactly the way it appears. Blacks are black. Graysare gray. Whites are white.
Retracting the Sekonic L-358’s Lumisphere enables you toquickly judge the brightness of multiple light sources for fast,accurate adjustment of lighting ratios.
Ambient Light Metering
Take shutter-priority or aperture-priority readings from 30 minutes up to1/8000 second and f/1 to f/90.9 with ¹/10-stop accuracy. The L-358 displaysexposure both digitally and on an analog scale for easy readout. Customfunctions enable adjusting the shutter speed and aperture readout for full,half, and third-stop increments to mirror the setting of your camera. Youcan change exposure settings after reading and the meter will automaticallycompensate to maintain the proper exposure. And the extended sensitivityrange, EV -2 to 22.9 for ISO 100, allows taking exposure measurements invirtually any kind of light.
Flash Light Metering
Shutter-priority readings of flash light can be made with a synch cordor cordlessly at shutter speeds from 30 minutes to 1/1000 second.The L-358 automatically resets after each reading in cordless mode toenable fast adjustment of flash brightness. The multi-flash function enablesaccumulating an unlimited amount of flash pops for times when a singleflash pop cannot achieve the proper exposure or the amount of depth of fieldneeded for the subject.
Optional Radio Flash Triggering
Simply plug the optional Sekonic RT-32 Transmitter Module into the battery compartment and wirelessly trigger flash units up to 100 feet away. The transmitter offers 32 digital coded channels and Quad-Triggering Zones and
is compatible with PocketWizard® radio triggering systems, as well as the PocketWizard Wireless Freedom partners. Learn more about Radio Triggering.
The L-358 is especially useful for on-location shooting to lighten shadowsor reduce background detail. That’s because it measures ambient and flashsimultaneously and automatically indicates the percentage of flash in thetotal exposure. You can easily adjust the ambient flash mix by turning theJog Wheel. The digital display indicates the camera settings and an analogdisplay shows the relationship between ambient and flash and the totalexposure.
Sekonic L-358 Functions
All controls are at your finger tips. Familiar Jog Wheel operation and large LCD readout make settings fast and easy.
Setting up lighting ratios or checking the evenness of a backgroundor scene is push-button simple. Take a reading of the key or referencelight and press the AVE/?EV button to create a standard. Then pressthe measuring button to display the brightness difference between the standard and new reading.
