Film
plane
indicator @
The film
plane
indicator
(-e-) is
engraved
in white
on
the
top
deck
just
behind
the
shutter
speed
dial.
It
indicates
the
exact
position of
the
film
plane
inside
the
camera
.
Whenever
it
becomes
necessary
to
measure
the
exact
distance
between
the
subject
and
film
plane,
such
as in
macrophotography,
use
the
film
plane
indicator
. The
distance
between
the
film
plane
and
the
lens
mounting
flange® is exactly
46.5mm.
Infrared
focusing
index
The
red
dot
beside
the
focusing index
on
most lenses
is
the
infrared
focusing index.
When
shooting with
black-and
-white
infrared
film,
it
is
necessary
to refocus
31
the
lens to
compensate
for
the
fact that
infrared
light rays
focus at a point slightly in front
of
visible light.
To
use
the
index, first focus
on
your subject
through
the viewfinder.
Then look at
the
lens
and
take note of
the
focused dis-
tance
. Finally
reset
the
focusing
ring
so that
the
desired
distance
is
aligned
with
the
red
dot.
