1 Set the Film Speed (ASA or DIN).
Lift and turn the external ring of the shutter speed dial so that the reading of the sensitivity speed of the film used in the camera
appears in the Film Speed Indicator Window.
Manual Aperture
(Stopped-Down Aperture Measurement)
The lens is stopped down to measure light when a preset or click aperture lens is used or when the automatic aperture system may
not be put to use due to the utilization of an extension ring or bellows.
21 Determine
the Shutter Speed.
Turn the Shutter Speed Dial 8 , select a shutter speed suitable for your subject and bring the reading of this speed in line with the
index mark.
3
Determine the Exposure.
Train the camera at your subject, look through the viewfinder and turn the aperture ring so that the Meter Needle 42 will come in
line with the Index Mark 39; visible in the viewfinder. Correct exposure is assured when the meter needle is aligned with the index
mark. Focus the lens and frame the subject before the shutter button is depressed.
IMPORTANT POINTS OF STOPPED-DOWN APERTURE MEASUREMENT
The stopped-down aperture measurement system has nothing directly to do with the aperture scale visible in the field of view. In
the event that the meter needle does not come in line with the index mark even if the aperture ring is turned, select another shutter
speed. If the needle comes above the index mark, pictures will be under-exposed. Here, select a slower shutter speed. If it comes
below the index mark, choose a faster speed.
Q There is no aperture in microphotography. Here, pictures must be taken while the shutter speed and the lights are adjusted.
Q When the lens is stopped down for a close-up, select a correct exposure while seeing to it that strong light does not come in the
camera through the eyepiece.
