Intended Usage

The meter is designed for:

Measurement of artificial light sources or natural light for photo, video, or movie

Display of latitude (dynamic range) from the shadow to the highlight of a digital

camera

Measurement of the flash high-speed synchro exposure or flash duration time for

diversifying flash shooting

Flash unit triggering and power control functions with the transmitter (sold

separately)

High-level measurement accuracy and a wide measurement range in all shooting

situations from outdoor to indoor with all weather design

Features of the L-858D

[Basic functions and performance]

1

Model with incident light and reflected light (spot photometry 1 degree) systems

2

One-touch switching between extended lumisphere and retracted lumisphere (Light

receiving part up-down mechanism)

3

Flash Analyzing Function which provides the percentage of flash in total exposure as

well as ambient and flash components.

4

Exposure Profile Function (using the Data Transfer Software application software)

5

Simplified luminance measurement (cd/m

2

,

Foot-lambert) and simplified illuminance

measurement (Lux, Foot-candle)

[New functions and performance]

1

2.7-inch liquid-crystal color touch panel

The operability is enhanced by assigning frequently used functions to Function Buttons

at the bottom of the screen.

2

Flash duration analysis (1/40 to 1/55,500 sec., t0.1 to t0.9, which can be changed in

0.1 steps)

3

Exposure measurement in HSS (High Speed Synchro) Mode

4

Improvement of lower light measurement performance (from -5 EV in incident light

measuring, from -1 EV in reflected light measuring) (based on ISO100).

5

Flash units triggering and power control functions with multi-brands of the transmitter

(sold separately)

6

Enhancement of video/cine functions such as frame rate setting (1 to 1,000 f/s),

shutter

angle setting (1 to 358 degrees), and filter compensation is possible. (+/-12 EV value,
