Normal AUTO Flash

Operation >

Along with TTL Auto flash in which exposures are controlled by the camera's independent sensor, the TLA30 also offers Normal

Auto flash over two aperture ranges, using its foreside sensor to control for correct exposure. When used with a Contax featuring

the direct TTL auto flash metering system or even with the Yashica FX-D Quartz, merely set the camera to the auto mode. Upon

recycling of the flash unit, the camera will automatically switch over to its flash synch speed and the viewfinder LED will indicate

flash-ready status. And, even when its shutter control dial is set at faster than the flash synch speed, the camera will automatically

switch to the flash synch speed as soon as the flash unit has completed its recycling.

1) Set the Camera on Auto Mode. The camera is set on the auto mode by turning the shutter control dial to "A".

3) Set the Aperture. Set the aperture ring to either of the two settings indicated by the red and green index marks for the Normal

Auto flash mode. For instance, when using an ASA/ISO 100 film speed, the correct coverage apertures will be f/8 and f/4. Check

the Auto Flash Range Guide for the correct flash range for the applicable aperture. When the extreme right (thick white band) of the

white band is aligned with the index mark for Normal Auto flash, the white band indicates the flash range for the flash unit. For

instance, you should keep your flash -to-subject distance between 0.7 and 4 meters approximately and between 1 and 9 meters

approximately for flash exposures at f/8 and f/4 aperture settings respectively as indicated by the green and red index marks.

5) Checking LED Display Inside Viewfinder. Turn the flash unit's power switch to "ON", and press the camera's exposure check

button to see if the LED display inside the viewfinder lights. The display here is the same as that seen in the TTL Auto mode).

Note: Since the camera's direct TTL metering function is operative even in the normal auto flash mode, you will sometimes see the

after-flash mark " " pulsate. Thus, be sure to check for correctness of the flash range by using the flash unit's Auto Check lamp.

MANUAL FLASH

OPERATION >

When you want to take flash photographs at certain fixed flash outputs depending on your photographic intentions or the prevailing

picture-taking situation, you have the option of using any one of three manual flash modes, the "F" mode for full output, and the

"1/4" and "1/16" modes for reduced outputs. When used with a Contax featuring the direct TTL auto flash metering system or the

Yashica FX-D Quartz or equivalent camera bodies, merely set the camera to the auto mode as in the case of normal auto flash

operation. As soon as the flash unit has completed its recycling, the camera will automatically switch to its flash synch speed and

the viewfinder LED will indicate flash-ready status. And, even if the camera is set at higher than its flash synch speed, it will be

automatically switched to its flash synch speed when the flash unit has completed recycling.

1) Set the Camera on Auto Mode. The camera is set on the auto mode by turning the shutter control dial to "A".
