The Sekonic L-558CINE DUALMASTER is the most advanced handheld light-measuring instrument available in the motion picture and video industry today. It meets and excedes the demands of Professional Cinematographers as well as Professional Still Photographers. It is the first to offer a 1° parallax-free spot viewfinder with a digital display. A built-in retractable incident Lumisphere for standard or cosine corrected light readings, provides both hemispherical and narrow angle readings. The L-558CINE DUALMASTER will handle any lighting situation. It offers foot-candle, lux, foot-lambert and cd/m2 measuring modes plus cine shutter speeds from 1 to 1000 fps and shutter angle settings from 1° to 270°.

FEATURES:

• Spot with Digital Display
  The L-558CINE DUALMASTER features a rectangular 1° parallax-free spot viewfinder. In dim or bright light situations, the L-558CINE DUALMASTER's spot viewfinder displays shutter speeds, aperture and more. The built-in spot meter measures both reflected ambient, flash or combined lighting. The optical finder also features an eyepiece with an adjustable diopter.
  
• Shutter Angle
  Settings are available from 1° to 270° plus 1°, 2°, 3°, 4°, 6°, 7°, 8°, 9°, 12°, 17°, 22°, 144° and 172°
  
• Cine Speeds
  1 thru 1000 fps. (frames per second)
  
• Analog f/stop Display
  f/0.5 to f/45 (in 1/3 steps)
  
• Light Measurement Modes
  Footcandle 0.10 to 180,000
  Lux 0.63 to 190,000
  Cd/m2 0.25 to 190,000
  Foot-lambert 0.07 to 190,000
  EV (Incident) EV -2 to EV 22.9
  EV (Reflected) EV 1 to EV 24.4 (with 1° spot viewfinder)
  
• Filter Compensation Settings
  Selectable on ISO 2: 85, N3, N6, N9, A3, A6, A9 or +/- 5.0EV in 1/10 step increments
  
• 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 L-558CINE DUALMASTER 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 meter's measuring button, without walking over to each light and turning it on or off.
  
• Memory Mode
  Up to nine readings can be memorized in incident or spot metering modes independently in both Aperture and Shutter Priority Modes.
  
• Full, 1/2 or 1/3-step Selectable Readings
  Both shutter speeds and apertures can be displayed in either full, 1/2 or 1/3-step increments plus 1/10 stop units to match your film or digital camera; selecting these increments is quick and easy with custom software menu settings.
  
• Exposure and Calibration Compensation
  Independent incident and reflected exposure compensation of up to +/-9.9 EV
  Calibration compensation of +/-1.0 EV
  
• Dual ISO Settings
  The L-558CINE DUALMASTER offers the flexibility of taking a single measurement and displaying the f-stop and shutter speed for two different ISO film speeds.
