Sekonic DUALMASTER L-558 CINE Opearting Manual page 3

Congratulations on your purchase of a
Sekonic DUALMASTER L-558/L-558CINE
Exposure Meter
The DUALMASTER L-558/L-558CINE is the latest addition to the extensive line
of Sekonic Exposure Meters, which have been market leaders for over 50 years.
The DUALMASTER was designed to offer more of what today's photographer
needs, and less of what they don't. It offers flash and ambient exposure metering
in both spot and incident modes. The DUALMASTER is the first multi-function
meter to offer a 1-degree (nine element camera-quality) spot that measures
reflected flash output as low as f/2.0. Along with its many unique features, the L-
558 is also capable of wireless flash triggering with an optional radio module.
Utilizing rubber seals throughout the housing and controls of the meter, the
DualMaster is water and moisture resistant. Although the meter can be used in
rainy or wet conditions, it should not be used underwater.
The large LCD panel makes reading the data easy and convenient; the panel
illuminates automatically in low light surroundings.
In order to retain the simple stylish look of the DUALMASTER, less frequently
used functions and controls are confined to custom software settings.
The DUALMASTER L-558 and L-558CINE is loaded with many features and control
options. Since each of these features has a detailed explanation, this instruction
booklet is extensive. We recommend that you read the manual to familiarize
yourself with the potential of the meter. Once you have established which features
and functions are important to you, refer to these sections only.
The DUALMASTER has undergone extensive quality control at every step of
manufacture. Please read this instruction manual thoroughly, to be able to take
advantage of its many features and to obtain the long service life that it was
designed to offer you.
Thank you for investing in Sekonic.
