[. . . ] SEKONIC Zoom Master L-508 Operating Manual Congratulations on your purchase of a Sekonic Zoom Master L-508 Exposure Meter. The Zoom Master L-508 is the latest addition to the extensive line of Sekonic Exposure Meters which have been market leaders for over four decades. It was designed to be the ultimate meter, a do-all instrument for the most demanding pros. Nine camera-quality lens elements are required to accomplish its 1° to 4° zoom range. Its large LCD display makes readings easy and lights up automatically in dark surroundings. [. . . ] Hold down the Mode set button 10 and turn the Set/change dial 5 to select EV value mode. At the same time, the shutter speed will be displayed in the digital display area, and the corresponding f stop will be displayed in the analog display area. While pressing the measuring button, the meter measures continuously until it is released. 2. Turn the Set/change dial to select the Cine Speed for the camera that will be used. Cine Speed is displayed after 1/8000, 1/200, 1/400 and the unit are in frames per second (FPS). The following Cine Speeds will display: 2, 3, 4, 6, 8, 12, 16, 18, 24, 25, 30, 32, 36, 40, 48, 60, 64, 72, 96, 120, 128, 150, 200, 240, 256, 300 and 360 FPS. 2. · The shutter opening angle that these speeds are based on, is 180 degrees. For other angles make the following ISO film speed corrections. * Example of correction value -1/3: Decrease ISO film speed by 1/3 stop, example: ISO 100 -1/3 stop = ISO 80 +1/3: Increase ISO film speed by 1/3 stop, example: ISO 100 +1/3 stop = ISO 125 4. While pressing the measuring button, the meter measures continuously until it is released. Reference: ·"E. u" (Exposure under) or "E. o" (Exposure over) appears when the combination of shutter speed and aperture is not possible for the measured light level. Changing the shutter speed and or aperture with the Set/change dial will allow you to find a combination that is possible. If the "E. u" or "E. o" readout blinks, this indicates that the light level is beyond the measurement range of the light meter. -11- -12- 5. Measuring flash light This method of measurement can be done in the following modes; with cord, without cord, multiple flash with cord, and multiple flash without cord. The measured value displayed is the sum of the flash portion and the ambient light portion. 2-1 Cord Flash mode The most positive method to assure proper synchronization and measurement of flash units. Connect the flash synchro cord to the Synchro terminal 8 on the exposure meter. 5. Measurement 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 flash cordless mode, and keep the Synchro terminal cap in place. NOTE: · The electronic fire unit may fire when you connect the Synchro cord or operate the POWER Switch. · For flash units with extremely low electric trigger voltage, the flash may not fire. In this case, make measurements in flash mode without cord (see page 15). Reference: · The shutter speed can be set in single or half steps from 1 second 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. [. . . ] The index correction will change in -0. 1 EV steps up to -9. 9. NOTE: · Make corrections after a sufficient number of test in actual photographic conditions, to suit your needs. If recalibration has been made for specific purpose do not forget to return to original zero settings. -23- -24- 7. Accessories Mini Light Receptor (Sold separately) · Incident light receiving unit with a compact 12mm diameter light receiving surface. · For measuring narrow areas used for photographing small subjects or copy work.
