Nikon EL2 - Manual (Page 42)

Automatic Shutter Speed Selection
When set to the “A” shutter-speed dial setting, the EL2
is capable of fully automatic selection of the shutter
speed appropriate for the aperture setting of the lens
and the existing lighting conditions. The exposure meter
display, visible within the viewfield of the finder, en­
ables the photographer to maintain continuous control
over the exposure while viewing and focusing, and with­
out the need of removing the eye from the viewfinder.
And as lighting conditions (or the aperture setting)
change, the shutter speed control circuit continues to
maintain continuous and automatic control, for perfect
exposure every time.
To take a picture using automatic shutter speed selec­
tion, first set the shutter-speed dial to “A” (the green
needle in the finder will move to the upper “A” posi­
tion and remain) and select an appropriate aperture set­
ting. As you compose and focus, the black needle will
continuously indicate the shutter speed being selected
for correct exposure. Prior to exposing the film, verify
that the needle is indicating a shutter speed appropriate
for the subject; if the indicated speed is too fast or too
slow, simply adjust the aperture ring on the lens until
the desired shutter speed is indicated. Then, press the
shutter release button to expose the film. Note that as
long as the needle remains within the scale, provided the
EV range of the metering system is not exceeded, the
camera provides the correct exposure automatically.
