Stop-Down
Exposure
Measurement
With
the
following
lenses
and
accessories,
full-aperture
exposure
measurement
is
not possible,
either
because
the
lens
has
no auto-diaphragm
or because
the dia-
phragm
will
not
couple
with
the
meter.
Therefore,
ih.
rtop-down
method
must
be
used.
This
means
measuring
exPosure
with
the
lens aperture
diaphragm
stopped
down
to
the
takingaperture.
Push
the
camera's
couplirtg
pin
as
far to the
right as
it
will go
and
mount
a
lens or
a
lens-and-intermediate
urrit
1o
the
camera
in the
same
way
as
the
Nikkor
Auto
lenses. Switch
on th6
meter
in
the
usual
way.
