Set the aperture ring to the Electric Eye.
Turn the Aperture Ring '12) and bring the Electric-Eye Mark 10) in line with the index mark. The ring clicks into position at any f-
number calibration.
41 Train the camera at your
subject and
look
through the
viewfinder, and the meter will be visible
in the
field of
view.
If the Meter Needle (42) is visible within the correct exposure range, it will be possible to secure correct exposure. Focus the lens
and frame the subject before the Shutter Button (1) is depressed to take pictures under the Electric-Eye system.
METER COUPLING RANGE
The meter coupling range of KONICA AUTOREFLEX A is, irrespective of the film speed, from 1/15 to 1/500 sec. of the Shutter Speed
Scale (16i. Yellow digits, B, 1, 1/2, 1/4 and 1/8 sec. are not coupled.
In the case of light measurement at full lens opening, the meter will be interlocked (coupled) within the ranges given below.
With f/1.2: EV4.5 (f/1.2,1/15 sec.) - EV 17 (f/16, 1/500 sec.) With f/1.4: EV5 (f/1.4,1/15 sec.) - EV 17 (f/16, 1/500 ec.) With f/1.8: EV
5.7 (f/1.8,1/15 sec.) - EV 1 7 (f/16,11/500 sec.)
NOTE: Upon changing the film speed and the shutter speed beyond the coupling range, the meter needle swings, but it is advisable
not to use the camera.
IMPORTANT POINTS FOR LIGHT MEASUREMENT
AT FULL
LENS OPENING
When under-exposure is recognized by the meter needle, select slow shutter speed. Whereas, in over-exposure, obtain fast shutter
speed. In case the meter is within a correct exposure range, it allows making EE photography. On the other hand, if the meter needle
is beyond the range, even changing of the shutter speed dial within a range from
1/15
to
1/500
sec., EE photography is impossible.
In the event that you want to give priority to the selection of a lens aperture over a shutter speed because of your specific
photographing purpose, turn the shutter speed dial while looking through the viewfinder and bring the meter needle in line with the
reading of the desired shutter speed. Make sure at all times that the shutter speed dial clicks into position at the calibration of a
desired shutter speed.

When the Electric-Eye system is not used ....
When there is the need to manually control exposure due to a specific photographing
purpose, turn the Aperture Ring ..12; to detach the Electric-Eye mark 10i from the index mark and an exposure is determined according
to the Manual Aperture Scale 11:'. Here, the meter visible in the field of view serves as a meter which is coupled to the film speed,
shutter speed and f-number at the full opening of the taking lens, and the Meter Needle (42) indicates a correct lens aperture. Read this
f-number and determine a proper lens aperture according to the manual aperture scale.
