Exposure and Light Meters

The new Sekonic L-558 DualMaster light meter is the world's most sensitive multi-function meter that can read flash down to an astounding f/2 (at ISO 100), twice as fast as any other multi-function meter available today. Pocket Wizard is available as an option therefore giving you the option to fire individual cameras and flash units remotely using a16/24 bit security-encoded digital signal. The L-558 fulfills the requirements of both the pro and serious enthusiast at a very competitive price point. The L-558 is priced at 400 and the L-558 Cine costs 450.

Features and Benefits

  • The L-558 includes Sekonic's unique built-in retractable Lumisphere. Simply turn the selector knob to extend it for 3D incident reading, or retract it for a narrow incident metering angle that's ideal for brightness evaluations, lighting ratio setups or precise readings of flat subjects.
  • The L-558 includes a true 1-degree spotmeter with a parallax-free viewfinder and in-finder, illuminated digital display that shows apertures in tenths, shutter speeds up to 1/8000 sec, and exposure compensation values.
  • The L-558 features an extra large, cool-green-illuminated full-information LCD panel that displays the complete range of readouts and modes as well as battery condition. It can memorize and recall up to nine readings in any mode, average them and display them individually on an analogue scale.
  • The L-558 includes a flash/ambient analysing mode that simultaneously reads both flash and ambient light automatically and can display combined flash-ambient readings, percentage of flash in the total exposure and simultaneous display of flash, ambient, and combined readings on an analogue scale. It also reads in shutter-priority, aperture- -priority or EV modes, and makes cumulative flash readings in cord or cordless mode.
  • The L-558 includes a broad range of custom settings that allow the pro or enthusiast to tailor it to their individual working methods. The body and controls are sealed to JIS water-resistance standards allowing it to be used confidently in any weather.
