twin-
lens
reflex camera. Turn either
of the
focusing
knobs

keeping the
image of
your
subject
centered
on
the
ground
glass
screen.
2.
When
using the eye-level
frame
viewfinder
in conjunc-
tion with
the
80-millimeter
lens, no masking
of the opening
of the
focusing
hood front
(7)
is necessary.
3.
When
using
65-,
105-, 135-,
and
180-millimeter lenses,
use the
appropriate
mask hooked on the
mask studs
(10).

CAUTIONS
l.
As
the
distance
between
the
lens
and
the
film
increases,
the
effective
brightness
decreases,
and
compensation
must
be
macle
to
obtain
correct
exposure
of
the
film.
when

ing

note
the

(26)
,

,
f t-rr examPle,
You
are
using
ancl
when
the
subject
is
in
sharp
focus
ili
the
8O-millimeter
lens,
the
exposure
correc-
tion
scale
(zti) indica-
tion
is
as
shown
in
the
cut,
exposure
must
be
doubled,
much
in
the
same
way
as
when
a
filter
of xz
rating
is
in
use.
If
the
brightness
of
Your
subject,
oS
measurecl
by
an
exposure
meter,
calls
for
1/60
second
ffi
n
'I
/l
at
f
/8,
then
you must
either
adjust
your
settings
to
1/30
second
at
f
/8
or
1/60
second at
f./5.6.
3.
In
adclition, compensation
must be
made for
parallax,
particularly
with
such wide angle
lens
as the
65-millimeter
assembly.
With
the
8O-millimeter
lens in use, when the distance
to
the
subject
is
down
to the
range calling for
X
1.5
exposure,
the
parallax can be corrected
by using the upper correction
line across
the
ground glass.
Compose
your
picture
so that
all
essentials
come
below this
line.
When
the subject is
even
closer, and
x2
exposure
is
needed, use the lower
correction
line
as
guide.
When
X3
exposure
is needed,
an
imaginary
line across
the
middle
of
the
ground
glass
screen
should be used as
the upper
limit.
This
principle
applies
to
lenses
of other
focal lengths,
but with the
1O5-millimeter
and
longer
focal length
lenses, the
cut-off
line
will
be
at
about
the second
correction
line
when
the
bellows
is fully
extended.
When
a tripod
or stand
is used, the
interpositioning of the
parallax compensation
mount
(PARAMENDER)
will
permit
you to
sight
and
focus without
any
parallax
whatsoever.
-t2-
DISTANCE SCATE
AND DEPTH OF
FIETD
1.
The
curves
and
scale
above the
exposure
correction
scale
(26)
constitute the
distance scale
(25).
The
point
at
which
the curve
meets
the
edge of the scale
indicates
the
distance
for the
lens in
use.
A separate scale
(blue)
is
provided,
however,
for
the
l35-millimeter
lens.
Another
scale for
65-
and
8O-millimeter
lenses is
nrovided
on
the
right side of the camera.
When
it is necessary to consult
the distance scale
while
t
using
the
grip
holder, use
this scale.
l
2.
When
it is necessary
to check the
available
depth
of
;
field, obtain
the
distance
to
the
subject
either by referring to
'l
the distance
scale
(25)
or by
actual
measurement,
then
make

use of the depth of
