Your camera's viewfinder is the reflex type and shows you exactly how
your picture or slide will appear.
1.
On the right-hand side of the viewfinder is a scale to check for
proper exposure. With the Lens Opening Control Ring on EE, and
the camera aimed at the subject, the Exposure Indicator should be in the
clear area for a good picture. If it is in the Overexposure Area, turn
to a faster shutter speed. If it is in the Underexposure Area, turn to
a slower shutter speed.
2.
Note that the Underexposure Area for the normal f/1.8 lens
is different than for the f/3.5 accessory lenses. If it is not
possible to move the exposure indicator into the clear area by either
slowing down or increasing the shutter speed setting, then the light
is too bright or too dim to obtain a proper exposure with the chosen
type of film.
