Checking the exposure
Checking the aperture:
The correct aperture setting for the shutter
speed to which the camera is set will be
shown by the needle in the finder. The
camera will automatically select this aperture
when the shutter is pressed.
* The proper exposure range varies according
to the open-aperture f-number and the
minimum stop-down f-number of the lens
used.
Under-exposure warning:
If the meter needle moves to the top of the
finder, there is not enough light for the
shutter speed you have set. Choose a slower
shutter speed to avoid an underexposure.
(The under-exposure limit mark shifts
according to the open aperture f-number of
the lens used.)
Over-exposure warning:
If the meter needle moves down to the bottom
of the finder or "22 " a faster shutter speed
may be needed to avoid an overexposure.
