In a automatic exposure operation (when the shutter speed dial is set to lock at "A" position or If the photographer wishes an indication of the approximate shutter speed the camera has selected, this is provided by the Viewfinder Data Display at a single touch of the Exposure Check Button, which turns the display on for 16 seconds.
The auto-selected shutter speed will be displayed by a digital LED steadily lit, to the right of the finder frame.
If two adjacent LEDs are lit, this indicates that the camera has selected a shutter speed which is in between the standard settings. (Both "500" and "250" lit would perhaps indicate a speed of 1/350 sec.). In case the ambient light is too intense to provide a correct exposure at the working aperture, the display will signal the need for selection of a smaller aperture by lighting the "
OVER" LED indicator. If the "
B" indicator lights, the exposure will fall between 4 and 16 seconds, or the scene is in danger of under exposure.
Manual Exposure Mode
Although in auto exposure is sufficiently good to cover most photographic situations, however, there may be time where the surrounding lighting condition is changing too rapidly to call for manual mode operation for consistent exposure control or for any reason If the photographer wishes to use the RTS II Quartz in Manual mode, setting shutter speed/aperture combination himself, the Shutter Speed Dial should first be unlocked from the "A" setting and set to any desired shutter speed.
After pressing the Exposure Check Button to activate the Viewfinder Display,
the photographer will see two of the shutter speed LEDs lit up. One of these will be lit steadily, indicated the proper shutter speed as determined by the camera's own SPD metering; the other will flash at regular intervals to indicate the actual speed at which the shutter dial is set.
To achieve a correct exposure, the photographer should adjust shutter and/or aperture settings until only one shutter speed LED is flashing steadily. At this point, the photographer may release the shutter, or may make fine adjustments of the aperture ring to achieve slight over or under exposure.
