The SPEEDMASTER L-858D is a photographic light meter with the following
features;

●

World's rst*1 HSS (High Speed Sync) ash measurement

●

Flash duration measurement

●

Multi-brand wireless triggering & control (with optional transmitter)

The multi-function SPEEDMASTER L-858D is the agship of the Sekonic family of
light meters. Offering reected-spot and incident light measurement of ambient and
ash 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, rubber­cushioned body. Weatherproong 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

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.

An exposure prole 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 prole, it is necessary to
do shooting in advance, and use the Data Transfer Software.

NOTICE

●

A protective sheet is attached to the LCD. Peel it off before use.

●

Although the LCD monitor is manufactured to very high standards, it is possible to

observe a few dead pixels on the screen. This is normal and not a malfunction of the
meter.

●

Do not use at altitudes above 2,000m (6,561 feet).

●

Our company shall not be liable for any data loss caused by, but not limited to, malicious

acts and control errors.

●

Be sure not to drop the meter or subject it to sudden impacts, as the meter will be

damaged.

●

Do not store the meter in areas of high temperature of high humidity, as the meter will be

damaged.

●

Be careful not to transport the meter from cold to warm moist conditions as condensation

will form on the meter and may damage it.

●

If the meter is operated in temperatures below -10°C, the response of the LCD will
greatly slow down and the display may be difcult to view and read. This will not harm
the meter. Also, if the temperature exceeds 50°C, the liquid crystal display will darken
and become difcult to read, but when it returns to room temperature it will return to its

normal condition.

●

If the meter is left in direct sunlight, a vehicle, or near a heater, the unit's temperature will

rise and may result in damage. Please be careful when using the meter in these types of
locations.

●

If the meter is left where corrosive gases may be generated, the gases may affect the

product and may result in damage. Please be careful when using the meter in these
types of locations.

●

Maintenance Notes

●

Be careful not to let the Light Receptor become dusty, dirty, or scratched as this may

affect the precision of the measurement.

●

If the meter becomes dirty, wipe it with a dry, soft cloth. Never use organic solvents such

as thinner or benzine.

NOTE

●

For used batteries, dispose of them according to the rules of your area, or bring them to

a battery recycling shop near you.

●

Insulate plus and minus terminals with tape or other insulation material.

●

Do not disassemble the batteries.

at the camera lens (lens optical axis) from a location

close to the subject, then make a measurement.

NOTICE

●

Try to minimize your inuence on the light measurement. Do not block the light
falling on the subject with your hand or body. Do not allow light toned clothing to
reect light into the meter.

●

Do not set the Lumisphere Retracting Ring 1 to an intermediate position. This will

change the quality of the light and produce an incorrect measurement.

●

Do not push down the Lumisphere 2 with your hand.

●

Because it may affect the precision of the measurements, be careful not to damage
or contaminate the Lumisphere 2. If the Lumisphere 2 becomes dirty, wipe it
with a dry soft cloth. Never use organic solvent such as thinner or benzene.

35

NOTE

If the Lumisphere 2 is damaged or stains cannot be removed,

purchase a replacement of lumisphere for L-858 separately, and

replace the defective lumisphere with the new one.

1) How to replace the Lumisphere 2

Push down the Lumisphere Lock Lever
both the upper and lower parts of Lumisphere Retracting Ring

, turn the ring counterclockwise to remove the lumisphere

1

unit.

2) How to attach the Lumisphere 2

Align the mark on the Lumisphere Retracting Ring 1 with the

mark on the meter head, and press the lumisphere unit in the
meter head. Then, turn the ring clockwise until it clicks into

place.
* Check to see that the Lumisphere Lock Lever k is engaged.
* When attaching/detaching the Lumisphere 2, be sure not to

4-2-2  Reected Light System

Switch the light receiving method to the reected light
system to make a measurement. The reected light

system measures the brightness (luminance) of the light

reected from the subject. It is useful to meter distant
objects such as landscapes, if you cannot go to the
location of the subject, or to meter subjects that generate
light (neon signs, etc.), highly reective surfaces, or
translucent subjects (stained glass, etc.). Although the
reected measurement is useful to see from the highlight
to shadow, the measured value should be compensated to
use as the proper exposure depending on the reectance
ratio. Reected light measurements are made by aligning
the circle in the viewnder with the subject area to be

measured at the camera position or in the camera
direction.

<<Step-up ring>> (Accessory sold separately)

You can attach a lter to the objective lens side using the step-up ring

Screen Display Details

When ash light is measured, f-stop (Ambient brightness + Flash brightness = total

exposure) is displayed on the screen.

The ratio of ash light to the total exposure is displayed in steps of 10%.
The analog scale displays the ambient component (orange line) and ash component (blue

line).

Example: As shown in the screen below, if the shutter speed is 1/125s and ISO

sensitivity is 100, the ash component and ambient light component will be
50%, respectively. The analog scale displays the measured value of both the
ash component (blue) and the ambient component (orange), and the photo

becomes a little yellowish if the tungsten light is used as the ambient light.
