TTIE MODEI,S
  The lkonta rollfilm cameras with rangefinder  fall into two
 main groups. These cover the Super lkonta models where
 the rangefinder is coupled to the focusing movement of the
 lens, and the lkonta M (formerly known as lkonta lll or
 Mess-lkonta) series where the rangefinder is built-in but
 not coupled with the lens.
  The name lkonta also is borne by cameras not covered in
 this guide, namely the rollfilm lkontas without rangefinder
 and the 35 mm. miniature lkonta.
  The rangefinder lkontas are constructed with particular
 regard to simple and quick handling, ability to stand up to
 hard wear, and full efticiency.
The Super lkontas
  Of the Super lkonta series Models lll and tV were in
 production up to 1959 and these, like all other models, are
 now discontinued. The following  is the full range of models
 that have been produced:
'1. 4.5 x 6 cm. SUPER IKONTAfor 16 pictures lf in. x 2| in. (4.5 x 6 cm.) on 2{ in. x 3f in. film (:" 120", "20"); some models are suitable
 for both "120" and the metal narrow core "620" spools. The weight  is
 19 ozs. and the dimensions are lft  in. x 3f in. x 4| in. The body is
 hard aluminium-alloy with hinged back the front is fully self-erecting,
 giving perfect rigidity, metal parts are stove enamel and fittings nickel-
 plated. Focusing is done by a built-in rangefinder which is coupled auto-
 matically to the focusing front cell of the camera lens. The front is
 connected with leather bellows to the camera back. Either the Novar
 f 3.5 or the Zeiss Tessar f 3.5 has been fitted in the Compur Shutter
 and the Compur Rapid shutter respectively. The finder is of the direct
 vision optical type. (Ihis model which first oppeared on the morket in June
 1934 hod the Code No. 530.)
  The last edition of this series has been fitted with a body release and
 some with Van Albada Finder.
   ln 1937 a second model of the Super lkonta was introduced (Code
No. 53l), incorporating double-exposure prevention device, body
 release, Van Albada viewfinder which opens automatically with the
 camera, and chrome finish of metal parts. Models made between 1946
and 1950 were fitted with the Schneider Xenar f 3.5.
   Models made since 1950 are again fitted with a coated Tessar f 3.5
 lens, and flash-synchronized Compur-Rapid shutter.

           ter.    Particulars see page 8.



        Model 530116 for  ll  exposures
          2f in. x 2* in. (6 x 6 cm.) is the
           predecessor of the 532116 model
           above and similar to it except that
          the range- and viewfinder are in
           separate eyepieces. The earlier
         models have no automatic film
           stop. The lens is the Zeiss Tessar
               f 3.5 or F 2.8 in a Compur-Rapid          shutter. Particulars on page 8.



         Model 533115 is similar to the
            5321|'6 model, but takes 12 ex-
           posures per film and has a built-
             in photo-electric exposure meter.
           Additional features: after thread-
           ing in the film, winding is fully
           automatic; a signal device shows
         red until all 12 exposures are
           made, at which point it changes to
         white.  Particulars see page 8.

with combined eyepiece for rangefinder and vievrfinder so that both
distance setting and viewing the image can be done at the same time,
and an automatic stop for the film transport has been fitted. As lens,
only the Tessar f 2.8 has been built in. (This model beors the Cade
No. 532/16.)
  In 1939 the Super lkonta 2f in. sq. with a built-in photo-electrlc
exposure meter was put on the market with the following additional
features: the capacity is l2 exposures; after threading in the film the
winding is fully automatic, a signal device shows red until all 12 ex-
posures are made, at which point it changes to white. In 1949 the same
qo{el was prod_uced with a different exposure meter. (Ihe Code No.
of this model is 533/ 16.)
  Since 1950 the Super lkonta 532116 has been known as the Super            f;
lkonta l(B), and model 533/16 with built-in exposure meter as ihe                                                                             iSuper lkonta ll (BX). Both have coated lenses and flash-synchronized                                                   I
shutters and take l2 exposures.
  The Super lkonto  lll was introduced in early 1954. lt takes l2 exposures
on standard 2f in.x3f, in. film ("120", "20"). lt weighe 24 ozs. and
measures 5| in.x4$ in.x lf in. The finish is black enamel, edges and
fittings are chrome, the covering is fine grain leather. The front cell
of the lens carries the distance scale from @ to 4 ft. and a depth of
field scale is engraved on the shutter front. The view finder is conibined
in one eyepiece with the rangefinder, but the coupling is different from
the earlier Super lkonta models. The Super lkonta  lll does not haye the
rotating wedge mounted on the front of the lens panel but uses the
mirror principle (see page l3). An accessory shoe is provided on the
t9p-olthecamera. A body release, film transport interlock preventing
double or blank exposures (with coloured indicating disc), an automatia
exposure counter, and a film indicator are provided. The lens is a
coated Novar f 3.5 in a Synchro-Compur  shutter; originally the Tessar
f 3.5 was also fitted. (The code No. is 531/16.)

Irens Coating
     The latest development in improving the performance of a
    photographic lens is a process generally called coating or
    blooming.  lt consists of the application of a microscopi-ally
    fine film of some inorganic substance on the glass sur-
    faces, which considerably reduces the light reflection
    between glass and air surfaces in the lens. The gain will be
     fully appreciated if it is understood that, for example, in a
    Tessar the loss of light due to surface reflection is in the
    region of about 35o/o, a figure which can be reduced by
    coating to about 5o/o. Apart from a gain in the speed of
    the   f ens which may be in actual practice 50% (:  half a stop),
     its main importance lies in the elimination of the scatter of
     light which impairs the contrast of the image. This results
     in a more brilliant negative, especially in the shadow regions
   where the tones are most subdued and so brilliance and
    contrast is most needed. The post-war Super lkonta models
    have factory-coated lenses. With the older cameras the
    coat,ing, however, can be undertaken by reliable optical
    manufacturers through photographic dealers. The fact that
    a lens has been coated can be recognized by observing in the
    lens reflections of, let us say, a lamp, which appear distinctly
    coloured, as a rule a rather deep blue with a tinge of red.
     The treatment and care of lenses is a matter of importance.
  On account of its chemical composition, optical glass of
    high quality is susceptible to the influence of moisture, and
    for this reason touching the glass with the fingers should
   be avoided. Since complete protection is impossible, the
    lens surface should be cleaned occasionally with a clean,
    soft chamois leather.
    THE LENS HOOD is a tube, as a rule made from metal,
    placed over the front of the lens to protect it from light
   coming from outside the actual picture area. There is no
    picture which could not be improved in clarity and brilliancy
   by the use of a lens hood. The wider the aperture of the
    lens the more important is the use of the lens hood. The

the two images fuse into one. The rangefinder  is then set to
the correct distance. With the lkonta M read off this
 subject distance and set the focusing scale on the lens mount
 to the same figure. On the Super lkontas the adjustment
 of the rangefinder automatically sets the lens to the correct
 distance.
Ttre Shutters
  The lkonta M models are fitted wirh Prontor SV or SVS
or Synchro-Compur shutters, while the Super lkonta
cameras have the Synchro-Compur and the Super lkonta lV
the Synchro-Compur with light value scale. The earlier
 models were fitted with the Compur or Compur Rapid,
except one 2f, x 3f in. Super lkonta which had a Klio shutter.
  The shutters require tensioning before each exposure and
are released by the camera body release. Early models had
no body release, the release lever on the shutter itself
 being used.
  The modern shutters (Prontor SV, SVS and Synchro-
Compur) are synchronized for use with flash bulbs and elec-
tronic flash at all speeds (see page 75).
  THE PRONTOR S, SV and SVS have 8 speeds: l, ll2, l/5, l/10,
 \125, 1150, lll00, and l/300 sec. (l/250 in 2f, x 3j in. lkonta M), and a
B setting for time exposures, as well as a built-in delayed action release.
  To set the shutter turn the outside milled ring until the top of the
{ia1no_nd 1nqlk I  points to the speed required. The engraved figures 1,2,5,   f 0,25,50, 100, and 300, stand for l,ll2,  I/5, l/10, 1125,-1150,
 !/100, and-l/300 sec. respectively. To tension the shutter pull the
tensioning lever on top of the shutter anti-clockwise  as far as it will go.
 A delayed action release (also called self-timer) is built into the
Prontor S, SV and SVS, and permits the photographer to appear in the
photograph himself. To use the delayed action ieldase, set th6 camera in
the usualw_ay and mount_it on a rigid support, best a tripod. In the
Prontor SVS, tensioning the shutter also winds the self-timer. On the
Prontor S and SV press down the delayed action setting lever as far as it
will go. This is the_lever with a red dot in its centre onthe lower part of
the shurter rrm. On pressing the shutter release, the shutter gbes off
after a delay of approximately 8 sec., giving the operator timelo take
his place in the picture. The synchronizing levei on the SV shutter
(see page 76) must be set to X when the self-timer is used.
 THE SYNCHRO-COMPUR AND COMPUR-RAPID  shutters have 9  15

Page 17 · Read text
speeds: l,  | 12, l/5, l/10, a 125, | 150, l/100, l/300, and l/500 sec. as well
              as a B setting for time exposures.
             The Synchro-Compur and recent Compur-Rapid shutters differ only
             in their flash synchronization (see page 76). Older Compur-Rapid
              shutters are not synchronized for flash, nor is the pre-war Compur.
           The latter has a top speed of l/300 sec. The older Compur-Rapid for
               larger sizes went up to l/400 s'ec.
             To set the shutter, turn the outside milled ring until the arrow head
              points to the speed required. The engraved figures, l, 2, 5, 10, 25, 50,
                 100, 300, and 500 stand for l,  | 12,l15,lll0,ll25,l/50,  l/100, l/300, and              l/500 sec. respectively. To tension the shutter, pull the tensioning
               lever on top of the shutter in a clockwise direct,ion as far as it will go.
             The speeds from I to l/10 and l/25 to l/300 sec. range continuously
            and may be set to any in-between value, i.e. setting between 50 and 100
              gives an exposure of l/75 sec. On the other hand no intermediate
                         ' speeds can be set between I sec. and B, between l/10 and l/25 sec.' or
            between l/300 and l/500 sec. When turning the outside milled ring of
              the shutterfrom l/300 to l/500 sec. a resistance is felt which is due to
            an additional spring needed to achieve this fastest speed. On the Com-
             pur shutter, with a top speed of l/300 sec., this spring comes into action
            between l/100 and l/300 sec.
           THE SYNCHRO COMPUR WITH LIGHT VALUES  ls the latest ver-
              sion of the Synchro-Compur shutter. lt is fitted with some different
              shutter speeds, namely, l, l12, l14, l18, l/15, l/30, l/60, lll75, 11250
           and l/500 sec. All the speeds (including l/500 sec.) can be set before or
                after tensioning. On the base of the shutter rim a range of numbers  is
            engraved in red from 2-18 which represent light values for correct
             exposure. Each light value represents a range ofshutter speed-aperture
             combinations, but is covered by a single setting. The built-in photo-
               electric exposure meter of the Super lkonta lV as well as the latest
            exposure meters are now also calibrated in light values; the reading
             can thus be transferred directly to the shutter.
            To set the light yalue, slightly pull out the serrated lever on the left
               of the shutter front and move  it to the appropriate light value on the
             scale. You can now choose any shutter speed or aperture without
             changing the exposure.  lf you alter the shutter speed, the aperture will
                set to the correct value, or if you change the aperture, the shutter speed
               adjusts itself automatically to keep the effective exposure constant.
           To change the shutter-aperture combination iust move the speed              setting ring until the aperture lever or speed index points to the
             required aperture or shutter speed respectively. Intermediate  light
              values can also be set, e.g. 5*, 6f, etc., for fully accurate work.
             The shutter may be used in the conventional way too; in this case the
              shutter speed has to be adjusted first and then the aperture.
             The shutter has a built-in delayed action release; to use it set the
               lever to V, but only ofter the shutter hos been tensioned. The lever will-
        .a  after release-have moved away from the V setting to prevent acci-      IO  dental delay release.

THE KLIO SHUTTER ha3 speeds from I to lll75 sec. B, T, and built-
    in delayed action.  lt is similar in manipulation to Prontor SV (see
   page l5).
    FOR TIME EXPOSURES with any of the shutters described, set the
    shutter speed ring to B (brief time).- The shu-tter requires tensioning
                                                                                  as     in the usual way. bn reliasing,-downthe-shutter will remain oPen as long    the release bution is pressed      and closes as soon as the Pressurc
   on the release is rem6ved. For such time exPosures the camera must
    be mounted on a firm support such as a tripod. lt is usually safest to
     release the shutter with thb help of a cable r-elease to avoid shaking the
   camera. This release is screwed into the cable release socket of the
    shutter (in models without body release), or in the centre of the body
    release (models with body release).
      For lo'ng time exposures-wher6 the shutter is to remain.open for
    longer thin you can conven-iently -keep the reJege depressed-a cable     rele-ase with iocking screw should be employed. To make the exPosure
    se1 the shutter to 6, depress the cable release plunger,_and tighten its
     fixing screw. The shuttir will now remain oPen until the fixing screw
     is unlocked.
        ln the older cameras with Compur shutter but no body release there
     is a "T" setting for long time exiosures. When the outer milled. ring
     is set to T the-shutteripens wlien the release lever is pressed down
   and will only close when the release is.pressed .a se.cond time. Con-
    sequently thb T setting is only employed-when the shutter. is.required
    to'remain open for a i-ong tirire-that  is, whenever it would be incon'
    venient or iinpracticable to keep the release lever pressed.
v   THE DELAYED ACTTON RELEASE of the Compur shutters (onlyA  built into the larser models) can only be used with the speeds from
      I to l/200 sec., bJt not with'B or thefastest speed. To use the delayed
    action release (for self-portraiture)  set the shutter to the speed required
    and tension in'the usuil way" The tensioning lever will come-to.a.stoP
     at a small milled knob (the'delayed action knob) which is pushed back'
   wards towards the camera body. The tensioning lever can now bc
    pulled farther to another stop. When the shutter release is pressed the
    ilockwork  is set in motion add after about l5 sec. automatically releases
    the shutter, thus giving the operator the chance of appearing in the
     picture.

        paper end is in line with the two white dots above and below the
         film aperture in the back of the camera.
      5. The back of the camera is now closed and made secure by trying
       to pull it open without touching the catch.
      7. The film winding key is now turned until No. I appears in the red
      window on the camera back. Where the window has a shutter
          this must, of course, be opened to allow observation. On the models
       with two windows,  it is always the one which is furthest oway from
        the film wind key which is used for setting film to No. l.
           ln Super lkonto 2[ x 2t in. (530115 ond 532116) proceed as above,
        then the film counter disc is pressed down and turned in the direc-
         tion of the arrow tothe number  l, when astrong resistance will be
         felt. Then release the disc. The camera is now ready for the first
        exPosure.
           ln Super ikonto 533116 (with Exposure Meter) no further winding
       beyond that indicated under No. 5 above is allowed until the film
        counter setting stud is pushed to the left, thus engaging the auto-
       matic counting device. The winding key is now turned in the
         direction of the arrow until it comes to a definite stop. The cut-out
      window of the film counter shows No. l. The camera is ready for
        the first exposure.
              In Super lkonta  lll and ,V (531 ll6) turn the film transport key until it
       comes to a definite stop. The film counter will now automatically
         indicate No. l.
         The Super lkonta lll, lV and lkonta M are fitted with a film indicator
       which should be set after loading the film. This shows the type
         (black-and-white or colour) and speed of film in the camera and thus
        helps you remember these details.

   camera is fitted. Full details on page 15.
4. On theSuper lkonta the distance is measured and se1 with the built-in
    ransefincier which is coupled to the lens. For handling the range-
    find-er see pages t4 and 52. The scale of focusing distances  is engraved
   on the outiia-e ofthe lens front. To setthe distance without using the
   rangefinder, the focusing ring is turned until the distance figu.re-
   reoiesentins the distance from the back ofthe camera to the subiect

   shutter casing.
     With the lkonto /14 determine the subiect distance with the help
   of the built-in rangefinder (see pages l4 and 52), and then set the
    lens to that distance as described above.

ficld covered by the camera is indicated by a whlte boundary line
        which seems to be just as far away as the subject. As some part of
         the surroundings of the field to be included on the negativrcutside
           '  the boundary line-remains visible through the finder,  it is possible
        to keep an eye on these surroundings at the same time. This is of
          particular value when photographing moving subjects. The actual
         handling of the finder is the same as described previously for the
         direct vision finder.
              ln theSuper lkonto2tin. x 3tin.comeroswith maskfortwo picture
          sizes, the finder also carries a mask to reduce the field of the finder
        for pictures of half-size.
     5. The exposure is made by pressing the body release veD/ gentl)'. ln
        early models without body release, press the release lever on the
        shutter. Exposures of ll25-l /50 sec. and less, are "instantaneous"       and can be taken from the hand. lt is, however, advisable to use
         l/25 sec. as sparingly as possible from the hand, as there is some
       danger of jerking the camera. Even a slight jerk, enlarged six or
         eight times on the print, results in unsatisfactory definition. On the
        other hand, if one has a steady hand and a chance of leaning against
       a wall or-even better-of supporting the camera on something
         firm, not only the l/25 but also l/10 and even l/5 sec. exposure can,
        with care, often be given without shaking. Time exposures should
       be made with the cable release. This screws into the cable-release
        socket of the shutter, in the case of a model without body release,
        otherwise into the body release socket.
            lkonto M and Super lkontos with double exposure interlock can
        only be released after the film has actually been wound on. The film
        winding key of these models sits on a slightly elevated metal plate
       which carries a small circular aperture, in which a red or white disc
       appears. The white disc indicates that the film has not yet been
      wound on, and that the shutter cannot be released. The red disc,
      on the other hand, shows that, the film has been transported and
        that pressure on the shutter release will expose it.  (This signal
        device is not incorporated in the 2[x2[ in. Super lkontas.)
          In Super lkonta 2i x 2[ in.: The film is wound by turning the
         film key as far as it will go.
            ln the older models, without automatic film lock, turn until the
        next number on the disc comes up to the index line.
    7. Winding Film in Models with One Window only: The film winding
        key is turned until first a hand and then a few dots have passed the
        film window and finally the figure I appears (as explained under
        Loading, page 20, No. 7). To get the film into position for the
       second exposure, the key is turned until No. 2 appears in the
       window and so on until all exposures have been taken.
