E OD MO

WARNING
Please place in a location where an infant cannot reach and accidentally get the strap wrapped around his or her neck. There is danger of strangulation. 2. Inserting the battery 1. Requires one 3.0 v CR123A lithium battery. 2. Open the Battery compartment cover latch !6 , and remove the Battery compartment cover !5. 3. Insert the battery, observing the polarity with the +,- marks in the battery compartment !7. 4. Align the tabs of the Battery compartment cover with the notches in the back of the meter, and press down to close the Battery cover latch. NOTE: To prevent loss of All-weather seal, be careful that dirt does not get stuck on the rubber seal and that the seal is not damaged. Remove battery if meter is not used for an extended period. Batteries can leak and damage the exposure meter. Dispose of used batteries properly. If the LCD does not light, check that the battery capacity is sufficient, and check that the battery positive and negative terminals are not reversed. The meter has a connector for a plug-in radio transmitter module. Do not remove the connector cover unless you are installing the radio module, failure to do so could cause the electronic circuit board to be exposed to damaging static electricity.
Checking battery capacity When the Power button !2 is ON, the battery power indicator on the LCD is displayed. (Displayed) Battery power level is good. (Displayed) Battery power level is low. Have a spare battery ready. (Blinking) Replace battery immediately.
Reference: We recommend you always have a spare battery on hand. If the liquid crystal display extinguishes immediately after the display appears when power is first applied, that is an indication that the battery is dead. Please promptly replace the battery. A three second pause between power on and off is recommended to avoid damage to the meter. -5-
4. Replacing battery during measurement or when using the memory function 1. Always turn the power OFF before replacing batteries. If batteries are removed with the power ON, measurements and settings in memory can no longer be recalled. 2. If after replacing the battery, or during measurements, strange screens (displays that have not been set) appear in the LCD, or nothing happens, no matter what button is pushed, remove the battery and wait at least ten seconds and then replace the battery. This allows the software to automatically reset.

3. When set for incident light 1. You can select extended or retracted lumisphere measuring positions by firmly rotating the lumisphere retracting ring (UP/DOWN) until it clicks into position.

Extended Lumisphere 2.

Retracted Lumisphere (Lumidisc)
When the Lumisphere is extended. (3-D Light Measurement) This is used to measure people, buildings, and other three dimensional objects. Measurements are basically made by the method of measuring with the lumisphere aimed in the camera direction (more precisely, in the direction of the lens axis) at the position of the subject. When the Lumisphere is retracted (flat diffuser function) This is used to measure manuscripts, paintings or other flat copy. It can also be used for measuring illumination levels (see page 26), or brightness difference (see page 24).
NOTE: If the device is used with the Lumisphere retracting ring in a middle position, distributed light quality will change, and suitable measurements cannot be made. Do not push the Lumisphere down manually. Always use the Lumisphere retracting ring. If the lumisphere becomes soiled, wipe it with a soft, dry cloth. Organic solutions (paint thinner, benzene, etc.) must not be used under any circumstances.
4. When set for reflected light (spot metering) 1. This method measures the brightness (luminance) of the light reflected from the subject. It is useful for distant objects such as landscapes, when you cannot go to the position of the subject, or for metering subjects that generate light (neon signs, etc.), highly reflective surfaces or translucent subjects (stained glass, etc.).
Take the measurement by aligning the circle inside the viewfinder with the subject area to be measured. The black circle A in the finder indicates the measurement range. The light receiving angle is 1 degree.
(Display in spot viewfinder)
< Diopter Adjustment > Turn the eyepiece @2 and adjust the diopter so that the circle in the finder is clearly visible when you look into the finder. < Step-Up Ring (Lens Hood)> (optional) The step-up ring (30.5mm 40.5mm), available as an optional accessory, makes it possible to mount step-up rings and filters. This simplifies the setting of exposure without the troublesome correction calculation of polarizing filters, etc. (see page 37) The step-up ring can also be used as a hood to protect the zoom lens from scratching, soiling, etc. < 2x Angle Converter > (optional) Mounting the 2x angle converter to the objective lens unit enables spot measurements at a light receiving angle of 2.

3. The shutter angle that these speeds are based on, is 180 degrees. For other angles make the following ISO film speed corrections (L-558 only). Shutter angle 160 degrees 220 degrees Amount of ISO film speed correction -1/3 +1/3
* Example of correction value -1/3: Decrease ISO film speed by 1/3 stop, example: ISO 80 -1/3 stop = ISO 64 +1/3: Increase ISO film speed by 1/3 stop, example: ISO 80 +1/3 stop = ISO 100 4. Press the Measuring button ! 4 to make a shutter speed value measurement. Release the Measuring button to complete the measurement. The measured value (f stop value) will be displayed. While pressing the measuring button, the meter measures continuously until it is released.

Set Measured f stop

Measured f stop on analog display
Reference: The L-558 displays the measured aperture value in either full or half stop increments on the analog scale, while L-558 CINE displays it in either full or 1/3 stop increments. Readings outside the display range or beyond the measuring range are similar to the previous instruction (see page 12).
5. Setting the shutter angle (558 CINE only). It is possible to set the shutter angle by turning the Jog wheel while pressing mode set button !0 and ISO2 button y.
Note: Shutter angle: The angle can be set in the range of 5 - 270 (in 5 steps) as well as 144 and 172. " " is displayed continuously on the LCD display if the shutter angle is set to any value other than 180. Press the mode set button and ISO2 button to confirm the shutter angle since it is not displayed.
Reference: This setting is only valid when the shutter speed is set to display cine speed (f/s) in the cine mode.
2. Measuring flash light This method of measurement can be done in the following modes; with cord, without cord, multiple flash with cord, multiple flash without cord and Wireless flash radio triggering mode (with optional radio transmitter module). When Measuring flash light, the shutter speed and F stop value (value combining ambient light and flash light: total amount of light) are displayed. The ambient light and flash light are each displayed as separate values together with the total amount of light on the analog scale. In addition, the ratio of flash light to the total amount of light is displayed at that time as a value in 10% steps.The flash reading is displayed as a blinking mark above the analog scale. (See page 32 for details) 2-1 Cord Flash mode Connect the meter to the flash with a synchronization cord. Be sure to replace Synchro terminal cap @0 after your measurement. 1. Connect the flash synchro cord to the Synchro terminal i on the exposure meter.

Please place in a location where an infant cannot reach and accidentally swallow the synchro terminal cap. There is danger of strangulation.

CAUTION:

There is danger of electric shock if the meter is handled with wet hands, during rain, in areas splashed by water or where there is a lot of moisture, if you use cord synchronized flash. Under such conditions, it is recommended that you use the meter in the cordless flash mode or Wireless flash radio triggering mode, and keep the Synchro terminal cap in place. NOTE: The electronic flash unit may trigger when you connect the Synchro cord or operate the POWER Switch. Triggering voltage is 2.0 to 400 volts. Below 2.0V, trigger flash with the cordless flash mode or wireless flash radio triggering mode, not with synchro cord. Reference: It is possible to switch the shutter speed between full, 1/2 and 1/3 stops by custom setting (refer to P32). The shutter speed can be set from 30 minutes to 1/1000 of a second. After 1/1000 sec, the meter can be set at the following intermediate speeds: 1/75, 1/80,1/90, 1/100, 1/200, or 1/400. If the film speed is changed after the measurement is taken, the new converted measured value (f stop value) will be displayed. After measurement, the F stop value corresponding to the shutter speed is displayed when the shutter speed is changed. E.u (Exposure under) or E.o (Exposure over) appears when the combination of shutter speed and aperture are outside the display range. Change the shutter speed with the Jog wheel and take measurements again. If the E.u or E.o readout blinks, this indicates that the light level is beyond the measurement range of the light meter.
2-2 Auto-reset cordless flash mode Measurements are made by the meter receiving the light from the flash. This measurement mode is used when the Synchro cord will not reach because of the distance between the flash and meter or when use of the Synchro cord is inconvenient. 1. Hold down the Mode set button !0 and turn the Jog wheel t to set Auto-reset Cordless Flash. mode
2. Turn the Jog wheel to set shutter speed. When setting shutter speed, first check the settings to confirm that they correspond to the settings available on the camera. -18-

4. Press the Measuring button !4 to trigger a flash. The measured f stop value at that time will be displayed. Each time this is repeated, the accumulated f stop value and the number of cumulative flashes is displayed.

Measured f stop (total exposure) 3rd. time
5. To clear the cumulative value, press M. CLEAR button @3 or switch to another mode by turning the Jog wheel while pressing the mode set button.
There is danger of electric shock if the meter is handled with wet hands, during rain, in areas splashed by water or where there is a lot of moisture. Under such conditions, it is recommended that you use the meter in the cordless flash mode, or wireless flash radio triggering mode and keep the Synchro terminal cap in place. NOTE: The flash unit may flash when you connect the synchro cord or operate the POWER switch. When firing a flash to take measurements, check the camera's synchronizing range and set the proper shutter speed. For flash units with low electric trigger voltage, the flash may not fire. In this case, make measurements in cordless flash mode or wireless flash radio triggering mode.
Reference: Setting the shutter speed is similar to the previous instruction (see page 17). Readings outside the display range or beyond the measuring range, are similar to the previous instruction (see page 18) of Cord flash mode of section 2-1. If the film speed is changed after the measurement is taken, the new converted measured value (f stop value) will be displayed.
2-4 Cordless multiple flash (cumulative) mode These measurements are used when the light generated by the flash is inadequate for proper exposure. The repeated flash pops can be accumulated until the desired aperture is displayed. The cumulative number is infinite. Only one digit is displayed if the cumulative number is ten or more. Display returns 0 (0=10, 1=11, 2=12 etc.) 1. Hold down the Mode set button !0 and turn the Jog wheel t to select flash measurement cordless multiple flash (cumulative) mode. Turn the Jog wheel to set shutter speed. When setting shutter speed, first check the settings to confirm that they correspond to the settings available on the camera.

9. Flash analyzing function When measuring flash light, the shutter speed and F stop value (value combining ambient light and flash light: total amount of light) are displayed in the liquid crystal display and the ambient light and flash light are each displayed as separate values together with the total amount of light on the analog scale. In addition, the ratio of flash light to the total amount of light is displayed at that time as a value in 10% steps. It is possible to use this value for adjustments, for example, when photographing with a flash in a room illuminated by tungsten light, to emphasize or weaken the tungsten (ambient) light element (enhancing the flash light of the photograph) to match the photographer's intentions. < Example > If, under certain conditions, the flash light component is 60% and the tungsten output component is 40%, the display will be as indicated at the right. Flash reading on the analog scale will blink.
Perecentage of flash in total exposure
To emphasize the tungsten (ambient) light (to imbue the atmosphere with orange-colored tones) To increase the ratio of tungsten light, use the Jog wheel t to change the shutter speed to a slower setting. It is apparent that the flash light component is now 20%. The analog scale also shows the tungsten output component to be about 2.5 stops higher than the flash light component. As a result, images on the film are expressed with orange tones that give life to the effect of the tungsten light.

Ambient

Measured f stop (total exposure)
To reduce the effect of tungsten light (to realize a more natural atmosphere) To decrease the ratio of tungsten light, use the Jog wheel to change the shutter speed to a faster setting. It is apparent that the flash light component is now 80%. The analog scale also shows the flash light component to be about 1.5 stops higher than the ambient light component. As a result, the images on the film are expressed in natural color tones.

Reference: Slower shutter speeds allow more available light to reach the film, and faster shutter speeds allow less available light to reach the film. The settings above are made by adjusting the tungsten (ambient) light by the shutter speed. It is also possible to modify the ratio by adjusting the flash light (when changing the distance between the flash and the subject or when changing the amount of light of the flash). When using this method, re-measure each time the flash light is adjusted. -31-

11. Wireless Flash radio triggering With the radio transmitter module plugged into the meters radio socket and a receiver (RR-4 or RR32 sold separately, or PocketWizard products; Classic, Plus, Max or MultiMax receivers) connected to one or more electronic flash units, the meter provides a convenient system that enables one person working alone to measure flash output without the need of a sync cord. Pressing the Measuring button simultaneously triggers the flash and measures the flash light. The L-558/558 CINE has 32 triggering channels when the radio triggering module (RT-32) is plugged into the radio socket. Channels 1-16 provide single triggering, while channels 17-32 offer selective quad-triggering capability. Selecting one of channels (17-32) provides control of up to four additional sub-channels (A, B, C and D). Selecting or deselecting of zone lighting is possible with sub-channels.

9. Safety Guide

WARNING: Please keep in a location where an infant cannot reach and accidentally get the strap wrapped around his neck. There is danger of strangulation. Never place batteries in fire, short, disassemble, or heat them. The batteries might break down, and cause injury or pollute the environment. Please place in a location where an infant cannot reach and accidentally swallow the synchro terminal cap. There is danger of strangulation.
Do not look directly at the sun through the viewfinder, because of potential eye injury. If you are operating the exposure meter in areas under wet conditions or high humidity, keep the sync post covered. If you are using flash in these conditions, Cordless Flash mode is recommended.
10. Care and Maintainance
Although this meter has an All-weather design for everyday use (JIS standard water resistance class 4), do not place it in water or use it underwater. This will cause it to malfunction.
Splashed Do not wash with water
Do not submerge or use under water
To avoid damaging this meter, never drop it or subject it to shock. Avoid storing it in places with high temperatures or humidity. Avoid excessive temperature changes which could cause internal condensation, resulting in malfunction.
Maintenance Notes If your meter is splashed with water, wipe immediately with a soft dry cloth. Avoid applying excessive force on the rubber seal of the battery compartment cover. Do not attempt to remove the rubber seal of the battery compartment cover. If the rubber seals surface is damaged,water or moisture may enter and damage the meter. If this has happened, you must send your meter to the Sekonic Sevice Center in your country. Keep the surface of the Lumisphere and the front and rear surface of the spot lens free from dust, dirt, and scratches, which could affect accuracy. Never use organic cleaners (like thinner or benzene). Clean with soft dry cloth.
