The Miroflex
a Combination Sport and Reflex Camera
In the Miroflex  all the special features of a Sport and
Press Camera are retained and, with a single movement
of the hand, the advantages of a Reflex camera are available.
   This unique combination has great significance for the
amateur. In the Miroflex he has an instrument which
is truthfully a "Universal" camera with which he is fully
equipped for any and every emergency. Sport, Street,
Marine, Children, Animals or Landscape subjects are
all equally within his capacity.
  We now give a brief description of the essential fea-
tures of the two camera types embodied in the Miroflex.

a) As Sport Camera
By a single pull on the handle beneath the lens panel the
camera is extended to the "Infinity" check and is im-
mediately ready for use. The lens panel is held perfectly
parallel with the plate by the absolutely rigid "lazy tongs".
By means of the simple spiral focussing lens mount the
camera can be focussed for distance while it is still closed.
Speed regulation of the shutter is simple and consists
of merely pulling out the regulating knob and turning
it according to scale.
    Without further manipulation any speed from'
           1ls to                                                  I lzooo second can be secured.

Should clouds impair the light  at the last moment,
         a longer exposure can be given by increasing the width
           of the slit in the shutter blind although the shutter is al-
           ready set. The perfectly vibrationless movement of the
           shutter operated by the wheel brake,
                uniformly reliable in Heat, Cold or Damp
t          gives accuracy and surety to the exposure. The lens-panel
         has a horizontal adjustment and permits the use of a
          ?e/e-?essar  fl 6.3, 25 cm focus, in  spiral-focussr'ng
          mount.
            The ground glass focussing screen can be used by press-
           ing a button, without altering the shutter setting. Dark
            slides or changing box can be employed with equal facility.
        The practically designed wireframe viewfinder with peep
{            sight permits rapid viewing and following of moving objects.
        b) As Reflex Camera s""                    o.u.                                                    'r,,'Y:?;.1'.'"'io"           Tl:e MiroIlex when closed is not larger than an ordinary
          Press Camera. By a single pull on the handle the camera
             is extended to the "Infinity"  check ready for use. The
          viewing hood springs open automatically on pressing a
          button and when not in use is easily folded away. The
            reflex mirror is coordinated with the Focal plane Shutter;
                  it allows the most accurate observation of the picture,
         which  it gives beautifully clear and sharp, and can be
           easily removed for cleaning or replacement. For sharp
           focussing from a tripod the picture is viewed on the ground
          glass focussing screen in the rear panel of the camera in
          the ordinary manner. Near focussing is obtained by the
           well known spiral focussing lens mount. The camera body
             is built  entirely of Aluminium  alloy of great strength
        and is covered with fine quality black Morocco leather.
         Hanging comfortably from the neck strap,  tl;.e Miroflex
             is easily and accurately operated, since the subject can be
           clearlyseen and focussed up to the very moment of exposure.

  When the Miroflex  is to be used as a Reflex camera
it must be hung around the neck by means of  the

leather strap and extended in the same way as men-
tioned above (Fig. 2). Now press with the index finger
of the right hand on the button at the right of the focussing               I

camera is closed) is accomplished by means of the Spiral

screen cover in the usual way and press with the  left
thumb on the small button underneath the focusing
screen, at the same time turning the rinq R of the focal

speed. The shutter has to be rewound for the exposure.
3. When tl:e MiroIlex  is used as a Reflex Camera the ob-
ject can be sharply focussed by watching the picture in the
focusing hood up to the moment of exposure. The mirror
mount cuts off some millimetres of the picture on the
groundglass, so that its size differs slightly from that of
the plate picture. The actual focus is varied by moving the
lever F/ of the spiral lens mount with the left hand, keeping
the index finger of the right hand on the release button
ready to make the exposure when the object is  in  the
desired position and correctly focussed (Fig. 4).
   For convenience when using a tripod, the lens panel can
be moved sideways. The knob screw ? in the lower left
corner of the lens panel must be slackened and tightened
again after the desired adjustment has been made.

Regulating the Focal-plane Shutter
Pull out the milled ring R of the shutter release knob A
till a noticeable resistance is felt and then turn the pointer u[
to the selected figure on the exposure scale, and let the
ring fall back in its normal position. In this manner all
instantaneous speeds from l/s to llzooo second can be
obtained, as well as Time and Bulb by placing at "T"
and "8" respectively. The shutter must then be wound
up by turning the ring A in the direction of the arrow
(clockwise)  till a firm check is reached. The exposure time
should generally be regulated before setting the shutter, and,
the shutter being set, should be altered only exceptionally,
and then only from a short to a longer exposure time.
Pull ring R outward and turn it to the left (not clockwise)
upon the desired speed number. Then let it fall back and
set the shutter once more arrowwise as far as it will go.
   Exposure is made by pressing with the first finger of
the right hand on the release button lV (see Fig. 4) or by

                              l2                      www.butkus.us

means of the wire release, screwed upon the thread of
button -h/. When using the mirror, the wire release should
not be employed.

Inserting the slide
Remove the ground glass frame by pushing upward the
catch in the upper right corner of the camera back and
insert the slide in its place.

Re-folding the Focussing hood
With the first fingers of both hands press the side panels
of the hood inwards as shown in Fig. 5 and the whole
hood can be folded down. When the cover is closed it
will be locked by the automatic catch.
Closing the Camera
After the focusing hood has been refolded as described and
the wire frame finder and peep sight have been replacec,
press with the finger of the right hand on the button at the
side of the carrying strap loop and with the left hand push
the front of the camera right back (Fig. 6). Then push the
opening handle upwards and the camera is locked.
  When closing rhe camera  it must be held horizontally.
If inclined forward for example, the mirror will touch the
lens and may be damaged.
  The camera must be closed slowly and there must
be no pressure with the fingers on the bellows as  it
would not fold correctly.
   For locking the camera, after having pushed the camera
front inside as far as possible, the handle Z must be
pushed upward. Another pressure on the camera front
will then lock it.

The camera should not be placed so that the button
for setting the shutter A  is below, as the weight of the
camera, especially  if  it is provided with a very heavy lens,
will press against this button and the button will weigh
upon the shutter mechanism'
   For this reason we recommend earnestly the use of
our special leather case, made for this camera' the inside
of which is so arranged that it  will prevent hurting  the
button A or weighing upon  it, so that the shutter me-
chanism may not be damaged.
  When introducing the camera into the case, the carry-
ing strap must be on the top and the lens directed to-
ward the lock of the case. Screw T  of the lens panel
must be tightened.

                                                                                   ll
Changing the lens  6u*K"5,a )The lens of the Miroflex can be replaced by others for
more special purposes. For interiors or night photography
tt.  2"i"" ressarfl4.5 can be replaced by a Tessar f iZ.Z,
in spiral focussing mount on a special metal .adapter ring.
For Telephotogt"ptty the Zeiss Tele-Tessar fl 6.3 in spiral
focussing mount can be fitted to the lens panel but
requires a special focussing adjustment'
  When the Tele-Tessar is used, it musf be dismounted
before closing the camera' otherwise the mirror and
focusing screen will be damaged.
   For changing remove the lens, slacken screw ? and
push the lens panel to the right.

   The Miraphof rs the ideal enlarging apparatus
because the manipulations
       a) of determining the size of the picture
       b) of sharp focussing
are done by ott" single control.  It  is sufficient to look
at the apparatus to be at once convinced by its practi-
