The multi-function SPEEDMASTER L-858D is the flagship of the Sekonic family of

light meters. Offering reflected-spot and incident light measurement of ambient and

flash light sources, the L-858D features a host of new functions and operations to

make it the perfect tool for all light measurement needs.

The color touch-screen panel is the control center of the ergonomic, rubber-

cushioned body. Weatherproofing seals enable using the L-858D in all shooting

conditions. Increased sensitivity and wide measuring range provide the high level of

accuracy demanded for today's digital imaging.
Using the Sekonic-developed Data Transfer Software

enables mapping your

camera's exposure profile and tuning the L-858D to your shooting style. Up to 10

Exposure Profiles

can be stored in the meter and called up anytime you need

them. Precision tuning of the L-858D enables instant check scene and subject

brightness against dynamic range of your camera for the very best exposure

decisions. The Data Transfer Software also allows customizing the L-858D to your

operating preferences.

To use this software, connect your computer to the L-858D using a USB cable (micro-B

type, available commercially).

An exposure profile contains information that indicates each characteristic feature (exposure

compensation amount between the camera and light meter, clipping point, and dynamic

range) of the digital camera you are using. To create the exposure profile, it is necessary to

do shooting in advance, and use the Data Transfer Software.
