number appears in the ASA dial window (Fig. 12) and then align the ASA/DIN number with the white
index line on the camera top cover by turning the. ASA/DIN ring.
THE SHUTTER SPEED SETTING:
Your Chinon C~3 Memotron camera is equipped with an electro magnetically controlled Seiko stepless
metal shutter for either automatic or manual exposure control. To set the camera for automatic shutter
speed selection, rotate the shutter speed dial until the "Auto" mark is opposite the index line on the camera
body
(Fig. 13). To set it for manual exposure control, turn the shutter speed dial until the desired shutter
speed is lined up with the index mark on the camera body.
THE APERTURE SETTING:
The aperture is set in the usual manner by rotating the lens diaphragm ring until the required F-stop is set
against the red diamond index mark on the lens barrel (Fig. 14, 15). With the shutter speed dial set at
"Auto", the electronic metering system will set the corresponding shutter speed to ensure correct exposure
of the film.
FOCUSING:
Your Chinon CE-3 Memotron has three methods of focusing: split image, microprism, and scale focusing.
Set the auto / manual control on the lens to the "Auto" position (Fig. 16). Observing the subject through the
viewfinder turn the focusing ring on the lens until the upper and lower split images in the microprism are
coincedent in the center of the viewfinder
(Fig. 17, 18). The focus can also be adjusted by the microprism
which surrounds the microprism disk by turning the focusing ring on the lens back and forth until the
image is perfectly sharp. This procedure ensures without a doubt that the image is at its sharpest setting.
Scale Focusing:
You may also focus by utilizing the engraved distance scale on the lens. Estimate or measure the camera to
subject distance in feet or meters then set the focusing ring to the appropriate setting (Fig. 19).
AUTOMATIC EXPOSURE:
The meter on / off switch is incorporated in the winding mechanism. It is therefore necessary to advance
the film advance lever before proceeding. Set the shutter speed dial to "Auto"
(Fig. 20) and select the
aperture according to your purpose for shooting the picture. Focus the subject. Depress the shutter release
button slowly and smoothly. When the shutter release button is half way depressed, the exposure meter
needle will indicate the correct shutter speed figure according to the light value which corresponds to the
chosen aperture value (Fig. 21). Further depression of the shutter release button will release the shutter at
the shutter speed indicated in the viewfinder.
EXPOSURE METER NEEDLE:
1. Over Exposure: Over exposure will be indicated by the meter needle moving into the upper striped area
of the viewfinder scale (Fig. 22). Should this occur the lens aperture must be reduced until the needle
enters the shutter speed scale. If the needle will not enter the scale a neutral density filter must be used.
2. Correct Exposure: The exposure meter needle stays within the scale (arrow marked) correct exposure
will result. It will be found when handling the camera that automatic shutter speed selection is a function of
the aperture and the ASA values chosen.
