Stopped-Down Measurement
The
PC-Nikkor lens must
be stopped down
to
deter-
mine
the exposure
when
used on
TTL
cameras.
Because the
finder image
progressively becomes darker
as the lens is stopped
down,
you should focus first
before taking a meter
reading.
It is
important
to
note
that
exposure measurement
must be performed before
the
lens is
shifted;
should
measurement be performed
after shifting, erroneous
meter readings may
occur.
With automatic exposure
cameras, such as the
Nikon F3
,
FE2
or
FE use
the
camera's
memory lock
to
retain the
correct shutter
speed before shifting the
lens
for the final
picture
composition.
Since
the
Nikon EM
doesn't
have
a
memory lock
,
the correct exposure cannot
be
obtain-
ed while shifting.
