Sekonic L-358 Flash Meter

Sekonic L-358 Flash Meter Features:
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.

  • The simple solution to creative light control with optional wireless triggering
    Directional light is powerful. It guides the viewer" creates mood" and adds dimension" depth" and texture. If you want to create a signature style that elevates your photography to the next level" the mastery of off-camera lighting should be your next goal.

    Subjects - clients - are not impressed with a shoot" view" and adjust photo style. Lighting ratios" ambient balance" and final exposure must be set confidently. Knowledge and use of the tools of photography assure that the outcome is the intended one. And for images like this one" the Sekonic L-358is the professional photographer's meter of choice.

  • Incident Light Metering
    Unlike in-camera metering" handheld" incident light meters don't require multi-patterned readings" complex exposure control systems" or +/- exposure correction when they fail. They are" in fact" the simplest and most direct way to determine exposure. And because incident meters measure the light that falls on your subject" they provide camera settings that render the image exactly the way it appears. Blacks are black. Grays are gray. Whites are white.

    Retracting the Sekonic L-358's Lumisphere enables you to quickly 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 displays exposure both digitally and on an analog scale for easy readout. Custom functions enable adjusting the shutter speed and aperture readout for full-" half-" and third-stop increments to mirror the setting of your camera. You can change exposure settings after reading and the meter will automatically compensate to maintain the proper exposure. And the extended sensitivity range" EV -2 to 22.9 for ISO 100" allows taking exposure measurements in virtually any kind of light.

  • Flash Light Metering
    Shutter-priority readings of flash light can be made with a synch cord or cordlessly at shutter speeds from 30 minutes to 1/1000 second.The L-358 automatically resets after each reading in cordless mode to enable fast adjustment of flash brightness. The multi-flash function enables accumulating an unlimited amount of flash pops for times when a single flash pop cannot achieve the proper exposure or the amount of depth of field needed 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 andis compatible with PocketWizard radio triggering systems" as well as the PocketWizard Wireless Freedom partners. Learn more about Radio Triggering.

  • Analyzing Function
    The L-358 is especially useful for on-location shooting to lighten shadows or reduce background detail. That's because it measures ambient and flash simultaneously and automatically indicates the percentage of flash in the total exposure. You can easily adjust the ambient flash mix by turning the Jog Wheel. The digital display indicates the camera settings and an analog display shows the relationship between ambient and flash and the total exposure.

  • Contrast Function
    Setting up lighting ratios or checking the evenness of a background or scene is push-button simple. Take a reading of the key or reference light and press the AVE/EV button to create a standard. Then press the measuring button to display the brightness difference between the standard and new reading.
