The IKoNTA M is an ingeniously constructed high
quality zErss rKoN camera with built-in range {inder
guaranteeing excellent, needlesharp pictures. Having
made yourself thoroughly familiar with the few mani-
pulations described in this instruction booklet, you will
easily obtain good pictures and you will derive great
pleasure from photography.
The rKoNTn iu furnishes 8 exposures/ 2'lr"X31l+",
on standard B IIl8 roll ftlm for the 21/r" X31/+" frames.
For ascertainment of the exact distance between object
and camera the rKoNrA u  is equipped with a built-in
precision range ftnder. The rKoNrA M is available
with a NovAR or a rESSen lens. All lenses of the
rKoNrA M, which are factory (T) coated in order to
eliminate flare and reflexes, ensure unmatched sharpness
and colour correction. An automatic shutter release lock
with signal device prevents double exposures.

EXPOSURE TIDIt,)
Turn the milled ring (4) until
the exposure tirne setting mark
is opposite the required expo-
sure tirne setting. The ftgures
indicate fractions of a second,
 i. e. 50 means Ll;o sec. When
usirrg setting "8", the shutter
remains open as long as the
release is pressed.
  The shutter must be wound
with the winding lever (8) prior
to every shot. It does not mat-
ter whether the shutter is wound
ftrst or whether the shutter
speed is set ftrst. The exposure
time must be set before the
shutter is wound only when the
shortest shutter speed (r/;oo sec)
of the Synchro-Compur shutter
is used.

TIT[' SITUTTER
The rKoNrA M is fitted either with a fully synchroniz-
ed Prontor-SV shutter or with a Synchro-Compur shut-
 ter. Both shutters are synchronized for flash, so that the
 canlera can be used with any current flash unit, e. g. the
ZEISS IKON II{OBLITZ  OT IKOTRON.
After setting the required shutter speed, the shutter is
wound by pushing Iever (8) as far as possible. The shut-
ter is released by pressing the body release (19). \When
setting "B" (tinre exposures) is used, the shutter remains
open as long as the release is pressed down. For time
exposures it is recomrnendable to use the cable release,
rvhich is fitted into the thread of the body release (19).
TIIE DIt f/AYED ACTION IBEI/EASm
After setting Iens aperture and distance, set push
lever (9) of the Prontor SV-shutter on the red dot
beside the X.
Then set shutter (8) and wind delayed action mecha-
nism by pushing lever (11) as far as possible.

In the case of the Synchro-
Compur shutter, push lever (8)
as far as possible, then move
back button (12) ancl push
lever (8) a little further, there-
by winding the delayed action
mechanisnr.
\,J(/hen release button (19) is
pressed down, the delayed
action mechanism starts run-
ning and automatically re-                Ileases the shutter after ap-
proximatelv 8 sec.
For time exposures (setting
"8") and the shortest shutter
speed (rlsoo sec.) of the Syn-
chro-Compur shutter the de-
layed action release cannot be
tused.

   \il/hen releasing the shutter, the built-in flash contact
   permits igniting the flash bulb connected to contact
   nipple (13), at the moment when the shutter is wide                                                                              !   op.n. The instructions for the various types of flash

  when the shutter is opened (position X) brrt also permit
   firing the flash ftrst and releasing the shutter after a

|rOIv TO USIC TIIE RANGEFINDBN
Looking through the rangefinder eyepiece you see in
the middle of the image a rectangular bright section
irr which the object appears with double contours. Turn
the focusing ring (20) of the range ftnder until the two
irnages merge. Then ascertain from the scale of the
distance meter the exact distance of the object. After
focusing the front lens (1) accordingly, you may rest
assured that the camera is correctly focused on the ob-
                              \When the ex-                                     iect.

The following method has proved to be the most prac-
tical one:
If  it is, for instance, intended to photograph a child
at play, the front lens is set on the most favorable
distance. By turning the focusing ring, the range ftnder
can be focused on the same distance as the lens. Then
observe the ch^ld through the rairgeftnder eyepiece
while slowly approaching the ch^td until the two range-
flinder images merge. Then, after a linal lool< through
the viervfinder, make the exposure.

I/ENS APERTURE' DEPTII  OX' I'IEI/I)'
AN D DXPOSURI) TI]IIE
 In good lighting conditiorrs a larger depth of fteld can
be obtained by reducing the lens aperture. Lens aper-
 ture and lens aperture settings are reciprocal,  i. e. the
smaller the lens aperture, the higher the lens aperture
setting ftgure. Every reduction of the lens aperture,
however, necessitates an increase of the exposure time.
In reducing the lens aperture, the depth of fteld in-
creases both in forward and backward direction from
the distance on which the lens is focused. The depth
of fteld for any given lens aperture and distance set-
ting can be ascertained from the depth-of-fteld
scale (3) of the carnera. The depth of ffeld can be read
off the distance settings opposite the two diaphragm
sctting ftgures on the right and left side of the setting
mark (2). Using distance setting 9 It. and diaphragm
setting "S" you can read off 8 on the left side and on
the right side 11. Consequently, everything between
B ft. and 1l ft. will be rendered sharply with diaphragm
setting "8" and distance setting 9 ft. The exact depth
of ffeld for any given lens aperture and distance set-
ting can be found on page 15.

The elegant zErs s r KoN Eveready Carrying Case
protects the rKoNrA M from dust and other detri-
mental external influences. The camera is screwed into
the case and need not be removed for taking a pic-

CABLE RELEASE
A cable release is especially useful for time exposures
and photographs from a tripod. It is screwed into the
thread of the body shutter release. The zErs s rKoN
cable release is equipped with a plunger catch for long
time exposures.
ZEIS S IKON FILTERS
inrprove the rendering of tone values in black and

42 mm filters, slipped on the front lens mount and
need not be removed when the camera is closed. Avail-

ultraviolet ftlters.
SUPPLEMENTARY LE NS ES FO:R CLOSE-U PS
Vith the standard lens equipment of the r K o N r A M
photographs can be made of objects from 5 ft. to in-

          finity. Objects closer than 5 ft. can be photographed
       only with the aid of supplementary lenses (z E r s s
      pRoxAR lenses), which are slippedror screwed on the
        front lens mount. Three different pRoxAR lenses are
         available for the IKoNTA M.
     Vhen using supplementary lenses, the photographer
       should take into account that due to parallax the
        viewftnder shows too much of the upper part of the
         object and cuts off part of the lower end of the object
       which is actually ernbraced by the camera,  i. e. when
       framing close-up obiects take care that you duly tilt
        the camera. See table on page 22.
     THE LENS HOOD
        prevents flare and haze in against-the-light  photo-
        graphs. Moreover, in bad weather, it protects the lens
       from rain and snow.
     COLOUR PIIOTOGiBAPHY
     The TKoNTA  r*,r is excellently suited for colour photo-
       graphy because it is equipped with high quality colour
        corrected z E I s s lenses. Contrary to black and white
          ftlms, colour ftlms pennit little deviation fro:n the exact
        required exposure time. Therefore, the photo-electric
        exposure meter zEISS rKoN tKopHor is indispensable
        for colour photography.
