2, Rotate the aperture ring to select the desired
f/stop. Turn on the main switch; a slight
depressing upon the shutter release button
will cause the LED indication of the shutter
speed to appear in the viewfinder.
Additional pressure on the button will release the
shutter to photograph the subject.
Visual warnings during aperture-priority AE control:
In the event light levels exceeds the shutter/
aperture coupling range, the shutter speed within
the viewfinder will be displayed in the following
manner:
W" — " ,r(flow-like
f- ~ I flickering)
Should the maximum aperture be indicated, select a
smaller aperture by rotating the ring toward the
direction of its minimum aperture {f/22, etc.).
However, if the aperture displayed is the minimum
aperture (f/22, etc.), rotate the same toward the
direction of the maximum aperture (f/2.8, etc.).
When the combination reaches the shutter/aperture
coupling range by changing the f/stop, the flow-like
flickering in sequence will cease; proper exposure
has been attained and photographs can be taken
safely with this AE mode. Should the light level
exceeds the meter coupling range the shutter
speed and''F--" indication within the viewfinder
will appear as follows:
I JO j (flow-like
' f-- ; I Lli_J flickering)
(Refer to page 27, "Beyond the meter coupling
range.")
