Exposure
warning
signal:
Should a "beep-beep" sound
be
emitted, note the position of the needle
in
the
shutter speed scale. If it swings past
1/1000sec. and stays within the
red
zone,
overexposure will result.
In
this case, reset lens aperture until the sound stops or the needle "drops" from the
red
zone
; despite the
sound, correct exposure is possible. If the needle is around
1/30sec
. or below, the sound merely warns
you
that camera shake may affect image sharpness because of the slow shutter
speed
.
You
either
read-
just aperture until the sound stops,
or,
if the needles is below 1/30sec., use a tripod to prevent picture
blur. The meter remains switched on for a brief period
even
after your finger is lifted off the shutter
release button.
Notes:
1.
At approximately 1/1000sec. or 1/30sec., a shrill sound may
be
emitted; it becomes regular when the
needle goes beyond these points.
2.
It
is
possible
you
won't
hear
the
waming
sound
in
noisy shooting situations.

The shutter speed should
