Sekonic L-558 Dual Master - Description:
The Sekonic L-558 DualMaster Light meter is the first multi-function light meter to offer a 1° spot meter that measures reflected flash output down to an amazing f/2.0 (ISO100). Sekonic L-558 DualMaster Flash Meter parallax-free lens eliminates erroneous close-up photography light readings. A digital readout through the spot viewfinder displays all-important exposure information.Sekonic L-558 DualMaster Flash Meter has An internal EL (Electro-Luminescent) digital panel displays data in all lightingconditions. As you would expect, the Sekonic L-558 DualMaster Light meter also includes a built-in retractable Lumisphere (incident dome) for full or narrow angle measurements.

The Sekonic L-558 DualMaster Flash Meter DualMaster's flexible design accommodates changing shooting situations. That's because Sekonic L-558 DualMaster Light metera multi-function meter. With aturn of a knob the Sekonic L-558 DualMaster Flash Meter changes from an incident meter to a reflective spot meter for both ambient and flash measurements, all in one rugged, compact, all-weather housing. Selecting aperture or shutter priority modes or EV is as easy as turning the Jog wheel. Simultaneous evaluation of ambient and flash is displayed in three convenient ways. L-558 DualMaster Light meter has An easy-to-read illuminated LCD panel, directly displays in full, 1/2 or 1/3-stop increments to match film or digital cameras. Sekonic L-558 DualMaster Flash Meter features such as meter calibration, exposure compensation and CINE settings offer the flexibility that today's photographer's require.

PLUS - The L-558 DualMaster Light meter incorporates the world's first optional internal Digital Radio Transmitter Module. Compatible with allPocketWizard Digital Radios, it provides wireless triggering and measuring of flash units and can even trigger cameras wirelessly. New, easy-to-use Selective Quad-Triggering control offers quick selection of which flash unit to trigger and measures each independently with a touch of a key.Spot with Digital Display The Sekonic L-558 DualMaster Flash Meter features a rectangular 1° parallax-free spot viewfinder. In dim or bright light situations, the Sekonic L-558 DualMaster Light meter spot viewfinder displays f-stops, shutter speeds and more. The built-in spot meter measures both reflected ambient, flash or combined lighting. The optical finder in Sekonic L-558 DualMaster Flash Meter also features an eyepiece with an adjustable diopter.

Optional Plug-in Radio Transmitter Module Electronic flash units and/or cameras can be triggered wirelessly with the optional plug-in digital radio Transmitter module (compatible with all PocketWizard Digital Radios).Simultaneous triggering and measuring of flash units up to 100 feet away is possible. With its new easy-to-use Selective Quad-Triggering control (4 zone lighting control), the Sekonic L-558 DualMaster Light meter offers quick selection of which flash unit to trigger and measure independently with a touch of a key. Now you can individually measure several flash units wirelessly by the touch of the Sekonic L-558 DualMaster Flash Meter measuring button, without walking over to each light and and turning it on or off.
