Mode Selection Your L-308Bll can measure both incident and reflected light in both ambient light and flash light (electronic flash or flash bulb) modes. You can switch the modes as follows: [Ligh&y.eng [Ligh$xec#ng [Measured light] [Mode/display method] see Page 7. 3.1 Switching between incident light metering and reflected light metering 5 Slide the lumisphere and stop it at the clicking position of "a" or "b" (See Fig.1 and 2). Lumisphere b Fig. 1 Incident light metering Caution: Fig. 2 Reflected light metering Fig. 3 1 Slide the lumisphere by pushing the part as shown in Fig. 3. 3.2 How to fit the Lumidisc 0 Slide the Lumisphere to the right for reflected light metering. (See Fig. 5) @ Insert the part (B) of the lumidisc aslant in the groove (A) of L-308Bll. (See Fig. 6). Then depress the strap eyelet (C) toward the L-308Bll body. (See Fig. 7) umisphere Fig. 4 Lumidisc Fig. 5 Fig. 6 Fig. 7 3.3 Caution: 3 How to remove the Lumidisc You may break the lumidisc if you do not take care when fitting and removin, g Take reverse procedures described above to remove the Lumidisc. 4, Light-receiving Method 4.1 Incident light metering Hold L-308BII close to the subject, point the lumisphere towards the camera, and measure the incident light intensity, (Fig. 8) ;Q,, //// II Fig. 8 Caution: Do not fit the Lumidisc next to the Lumisphere when you take incident light metering. Otherwise, the Lumidisc will affect the exposure in proper reading. 4.2 Reflected light metering You can meter the reflected light of the object by pointing the L-308Bll's lens at the object from the camera's position. (Fig. 9). Fig. 9 Caution: If you measure from the camera position, the entire object is measured in average. If you want to measure only a part of the object, do it at as close a position as possible to the part measured. Take care so that the part measured may not be shadowed by the meter, etc. 4 5. Preparation for Measurement 5.1 Inserting the battery Use a 1.5-volt, type-AA battery. Use a manganese dry cell (R6P) or an alkaline one (LR6). Never use any of other types. 0 To remove the battery case cover simply slide it in the direction of the arrow. 0 Insert the battery in the battery case aligning the polarities as indicated on the inside of the case. (Fig. 10) 8 Slide the battery case cover along the unit to close it. Check that the cover is securely closed. 5.2 Battery check Depress the POWER button, and the LCD panel ("b.c" message and bar marking $`i) displays the current battery level. The battery level is indicated by a number of bars for one second. Then, the LCD panel automatically switches to the normal measurement mode. piii?iq NOTES l l You can sustain battery level display by holding down the Power button. When the battery level is indicated by only two or three dots, prepare a new battery. When the battery capacity drops below the limit, the "b.c" display blinks and then disappears. 5.3 Auto Power-off To save battery capacity, the L-308Bll is automatically turned off (and all readings are erased) 4 minutes after your last operation. Press the mode selection button to select the desired measurement mode. Mode switching sequence: a Measurement mode Measurement mode with cord - ---II Measurement mode without cord 5 NOTE 0 If you press the mode selector in the ambient light measurement mode while holding down the IS0 button, the display is toggled between EV and F values (Fig. 12 and 13). If it is toggled after measurement, the measurement data is automatically recalculated and redisplayed. Fig. 12 Fig. 13 5.5 Setting up film speed (ISO) 0 Press the IS0 button, and a film speed value is displayed (Fig. 14). @ Set up the film speed by pressing the Up or Down button while holding down the IS0 button. If you press the Up Fig. 14 button, the speed increases; if you press the Down button it decreases. If you hold down the Up/Down button for more than one second, the speed changes continuously. NOTE l You can set up the film speed either before or after measurement. 5.6 Setting up shutter speed (T) Set up the shutter speed used by pressing the Up or Down button (Fig, 15). If you press the Up button, the speed increases; if you press the Down button it decreases. If YOU hold down the Up/Down button for more than one Fig. 15 second, the speed changes contrnuously @in the case of ambient light, you can set up the shutter speed in a range of 60 and NOTES 1/8000 sec. @ In the case of flash light, you can set up the synchronizing shutter speed in a range of 1 and 1/500 sec. After 1/500 see, 1/75 1/80 1/90, and 1/100 sec. are displayed in order. You can select any one you want. r 5.7 Setting up number of frames per second (f/s) The film frame counts are displayed after 1/8000 set of shutter speed in the ambient light mode. Choose any count you want (Fig. 16). NOTES l l Fig 16 The f/s count options are: 8, 12, 16, 18, 24, 25, 30, 32, 64, and 128. These values represent those used with the shutter angle 180 degrees. This setting up is used for a motion picture camera only. 6 6. Ambient Light Measurement 6.1 Mode Selection 0 Press the mode selector to enter the ambient light measurement mode. 0 Set up the film and shutter speeds. @ Press the measuring button, and the aperture value is displayed (Fig. 17). NOTES Fia. 17 0 Fig. 17 shows the shutter speed 1/125, and aperture F2.0+3/10 measured. l In the ambient light measurement mode, light measurement is continuously conducted while the measuring button is kept depressed. l If you changed the film speed (ISO) or the shutter speed (T) value after measurement, the measurement value is automatically recalculated and displayed again. l E.u (underexposure error) or E.o (overexposure error) is displayed if the metering range is exceeded. If E.u was displayed, reduce the shutter speed; if E.o was displayed, increase it. (Fig. 18) (Fig. 19) Fig. 18 Fig. 19 6.2 Measurement of EV (Exposure Value) Press the mode selector to enter the EV measurement mode. Press the measuring button, and the EV value is displayed (Fig. 20). Fig. 20 NOTE 1 l "EV" represents a specific amount of light, and is a combination of a shutter speed and an aperture value. 7 7.. Flash Measurement with cord 7.1 Setting up of the flash measurement with cord and making measurement in this mode 0 Press the mode selector to enter this mode (Fig. 21). @I Set up the film and shutter speeds. Fig. 21 Caution: l l Set up the shutter speed which has been already set up on your camera. If you measure the flash bulb light, make sure that the shutter speed set is within the synchronizing range. 0 Connect the synchro cord to the L-308Bll's synchro terminal (Fig. 22). B c--- J \F Fig. 22 Caution: @ Press the measuring button, and the flash fires and the aperture value is displayed (Fig. 23). NOTES ically recalculated and redis * Synchro cord (optional): A 5-meter-long synchro cord with three plugs is available for synchronous metering between your L-308Bll, the camera and the flash unit. It is very convenient as no cord replacement is required during shooting pictures. The L-308Bll is also equipped with a connector terminal lock for securing cable connection.
