FOCUSING
1. The method of focusing is the same as for any twin-
lens reflex camera. Turn either of the focusing knobs (1)
while 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).
LENSCHANGING
1. Before removing or fitting a lens-shutter assembly
turn focusing knob (1) to make certain that the lens mount
is fully retracted into the camera body.
2. Turn lens-shutter assembly change knob (22) to
..UNLOCK ".
3. Push lens-shutter catch lock button (23) toward front

5. To attach a lens-shutter as-

tion on the lens mount, then
secure in place by replacing the
lens-shutter assembly catch (24),
then turn the lens-shutter

automatically to lock position.
6. A red warning signal visible
under the ground glass screen
indicates that the lens-shutter
assembly change knob (22) is
at " UNLOCK " position, with
light barrecl from entering the
camera through the lens. Always
make sure that your camera is

On the right hand spool holder (16) there is a yellow
mark which moves when the crank is turned. This mark is
provided for your convenience: align the yellow mark with
the white mark on the camera body for easy loading and un-
loading of film.
3. After the film has been positioned over the film gate,
and the end has been secured to the take-up spool, turn the
filmwind crank (2), winding until the start mark (double-
headed arrow) printed on the paper backing of the film comes
into alignment with the start marks (18) near the upper side
of the film gate. (Fig. 7)
4. To close the backlid, always press the both sides of the
catch button tightly so that both right and left sides of the
back are securely engaged to the body. Lock by turning the
backlid catch button counterclockwise so that the red mark
moves through an arc of 90 degrees.
5. Turn filmwind crank (2) in clockwise direction until it
stops. The first frame of film will be correct position for
exposure, while the film counter ( ) will indicate numeral 1.
Turn crank counterclockwise until it stops, then fold out of
the way.
6. Repeat the above step after each operation of the shutter.

7. When the full number of exposures have been made,
continue winding the film until the film is completely wound
on the take-up spool. Remove film.
When the film is to be rewound completely after a short
length of film (six exposure color film, etc.) has be exposed,
or after exposing a specific number of frames, to take up the
film, wind up the exposed frame and cock the shutter. Then,
while depressing the shutter button of the camera body, turn
the filmwind crank. The entire film may be rewound in
one operation.
* Red window cover (13) can be slid down to ascertain
whether or not the camera contains film-
GAUTIONS
1. When the multiple exposure/filmstop selector (5) is set
at " ROLL FILM ", the shutter button (3) is operable once
only for each numeral, from L to L2, appearing in the film
counter window (4). This automatic locking of the shutter
button for prevention of multiple exposure does not occur
when no film is loaded.
When there is no film in the camera, crank operation will
not cause numerals to appear in the film counter window (4).
Consequently, the shutter button cannot be operated even with

PICTURE-TAKING
CLOSE.R,ANGE
PHOTOGRAPHY
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 undertak-
ing close-range photography, note the exposure correction
scale (26)
, and adjust shutterspeed or aperture accorcl
ingly'
(Fie.e)
2. lf

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 bedoubled, 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.

www.orphancameras.com

DISTANCESCATE
AND DEPTHOF 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 t'
use of the depth of field table. i
SINGTE EXPOSURE
