General notes

                                                                                                                                                                                                          .lThe novel design of the Ikoflex III makes it necessary for the user to read
the following instructions carefully.  It is only when the various move-
ments have been thoroughly understood that  successf ul  results in
practice can be expected.
                                                                                'itThe Ikoflex III  is designed in such a way that    is imlrossible to forget
any particular operation between exposures: the crank handle winding
on the film turns through 180o, and if  not turned through its  full
distance will not return to its original position.
This crank sets the shutter as it moves on the film to the next picture:
by this means double exposures as well as blank unexposed sections of
film are completely prevented
A picture counter indicates the number of exposures which have been
made, and after the l2th exposure the counter springs back to zero as
soon as the crank handle is wound, remaining there until a new film has
been loacled. As soon as the first section of film has heen wotrncl into
llosition the handle is Llt'hed anrl r:itttnol lrrr rnoverl:tg:tilt rrrrtil irn ex'

f. Suitable films to use.
The 'Ikoflex takes pictures 2rltx.2|la inches (6x.6 em) in size, and is used
with a standard B 2 wide tliameter spool, on which it gives 12 pictures.
The fast Zeiss Ikon Pant'hrom film is specially r""o-L"nded, since it
is always' reliable and gives excellent results even in had lighting contlitions.
The colour sensitivity of this film inclurles orange u"I      u, well as
the other colours, and all colours of the rainbow ur" ,"1r*oducecl"ud,-   in theircorrect relative brightnesses.
Spools of film rnust be kept in their original light-tight cartons ald
wrappings, and although the backing paper is impervious to light it  is
desirable to load and unload the camera in diffused weak liglt  or in
the shade" This will avoid any risk of fogging.

II. Loading the camera
Under the crank handle (6) will be
seen a small indicator (8). When
no film  is in the camera, a dark
area is seen through the circular
windowo but when a film has beerr
loaded into  the camera and  its
paper backing strip attached to the                             ooF"take-up spool, a large white      on
a red ground appears in the window
(8). It  is thus possible to ascertain
in a moment whether film is in the
camera or not.
The following operations are  re-
quired for,. loading, and must he
carried out in the orcler given below:
I. By moving the button (22) in
   the direction of the arro\tr' and
    simultaneously lifting the back of
   the camera, the latter swings gpen
   on its 'hinge.

2.  After  pulling outwards slightly
   the knob (26) and turning it  a
     little to the side to lock it in the
   outer position, a  full spool of
    film is placed orr the inside pin
   (27). The pointed end of  the
   bad<ing paper must point in the
    clirection of  the open camera
   back and the take-up chamber,
   the black surface being next to
   the camera body and not facing
   upwards. By turning the pin (26)
   bad< to  its original position, it
    will spring inwards once nlore
   and hold the epool of film in placr:.
.3. The gumstrip holding down the
   baeking paper of the film is now
   broken, and the paper clrawn
   over the open camera llack and
   threaded through the longer slot
   in the empty spool core placed
   in the take-up dramber.

    little,  until the two  triangular
   bla& marks on the bad<ing PaPer
   are opposite the two white intli-

    until the first section of film  is
   ready for  exposure inside the
   camera.'aThis is the case when
   the handle (6) locks, and will not
   turn further. SimultaneouslY the
                                                                     'L1.1)    picture counter (3) indicates

III. Taking the pieture
Focussing and coruposing the picture
are clone on the ground-glass screen
of the view-finder. The depth of
focus is indicated lry the  specill
scale (21) placed beside the focuss-
ittg control knob, and showing the
limits of sharp  f ocus for any lens
aperture which may be in use. In
the illustration opposite, the subject
focussed ie at 6 feet, and if may
lre seeen that at f ln  the limits of
focus are 5 and B feet.

1. Pressure on  the  button  (21)
   causes the hood of the finder to
   spring automatically into        . its
   working position.

:1.  For the very sharpest focus, par-
    ticularly at large aperture values,
     it  is useful to use the supple-
   mentary focussing magnifier (18).
   This springs upwards into  posi-
   tion when the small millecl lever
   (2) is pressed downrvards.

This is arranged by the unusual design of the finder itself: the white
   rectangle is       on the back wall of the finder surrounding th9                ""tnully              by the eye as a sight. The glass of the front portion of   aperture used
  the finder consists of two cemented lenses, the surface between the
  two |eing semi-silveredo and as a result this semi'reflecting surface
   lrrorluces an image of the white rectangle at the subject distance.  The finder rnust be held close to the ele,, so that the area surr-
  ounding the white rectangle can be clearly seen' though the area
                                                                          be   en"losfi |y the white lirres themselves is that which will actually
   inclutled in the picture taken by the camera lens. The front wall of
   the finder hood (I7) moves as the focussing control knob is turned,
  and thus compensates for variation in parallax at differerrt focussing
   distances. By this means it  is ensured that what appears within the
                                                                        nega-   white lines seen through the finder will actually appear in the

              8. When it  is required to  work
            with the delayed-action shutter
             release, the mechanism controll-
             ing this action, must first be set.
           This is done by pressing the
             frutton (7) on the camera front
           upwards in its slot until  it  will
           go no farther. The indicator (12)
            of the shutter will then show the
            white disc.
         The  delayed-action mechanisnr
            cannot be used for rfaooth second

Closing the finder hood
To close the finder hootl, the two side panels (l) and (2) are first folded
tlown, then the front panel (l?), and finally the bad< panel (19).
Safety devices
f)ouble-exposures on a single section of film are out of the question,
for the shutter can only be released when the film has been wound on
to the next picture. In the same walr the film eitnnot be wound on
rrrrtil the shutter has been released.
Apart from this mechanism, a  retl
disc shows in the window (I2) when
the shutter has heen set which also
means that the film has been wound
on. A blad< disc in the same window
indicates that the film needs wind-
ing on if another exposure is to be
made, and that the crank handle (6)
must be rotated.

If the crank handle (6) and the shutter release (5) are locked, force must
never be used to try to make them work. Locking of one or the other
merely implies that some operation has been forgotten.

Two-point foeus settings
In order to give the very greatest readiness for use at short irotice, the
Ikoflex III   it  fitted with the well-known Zeiss Ikon system for two'
point focus settings. If  the lens aperture is set to the red dot between f  ll'L
ind f 116, and the focussing control knoti to the similar red dot betweenZO and 30 feet, the depth oJ fo"or stretches between 13 feet and infinity.
                                                                                                        la,:kThis setting can be used for practically every exp_osure in which
of time foibids accurate focussing on the ground glass.

The lens aperture
The larger the nunrerical value ,rf
the lens aperture, the smaller the
actual aperture through which light
passes, and the greater is the depth
of focus. At the same timeo a srnall
aperture (i. e. large aperture num-
ber) implies a long exposure. The
aperture is adjusted by rneans of
the lever (13).

The lens aperture that has been set
appears in the small rvindow (15).
