Good photographs
can easily be obtained with your ZEISS IKON camera.
With the elegant and handy SUPER IKONTA every
picture will be needlesharp on account of the single
window coupled rangefinder
and you will find great
pleasure in your photos.
In order to utilize to the full all the advantages of
the camera it
is recommended that you study these
instructions carefully. Unfold the inner leaves of
the cover for further reference
and try to practice
the various mechanical movements before loading
the camera.
If you are still in doubt, do not hesitate
to ask your photo-dealer for advice.

THE MA IN FEAT U RES OF TH E
S U PE R I KONTA 2' /4X 2'/. in S.
The SUPER IKONTA 2'/. x 2'/. ins. is a high quality
roll film
camera for 12 exposures 2'/. x 21/ . ins. -
size on standard 120 roll film.
The value of a camera depends mainly on the qua-
lity of its lens.
The SUPER IKONTA is available
either with the world-famous ,Z EISS T E SSAR
1:3 . 5175 lillY! or the time-tested, reliable NOVAR
1:3.5175 nUll . Both lenses are colour-corrected and
factory-coated. They yield black and white as well
as colour pictures of unsurpassed definition and
brilliance.
The built-in ran ge fi nd er is coupled to the lens so
that correct focusing is guarant ee d. The rangefinder
is combined with the viewfinder ensuring not only
sharp pictures but the correct image field simul-
taneously, even of fast moving objects.
The re d-d ot se ttillg increases the versatility of the
camera and makes it ready for action any time you
want to take candid snapshots.
The SY ll c br o-C Of llp llr sbutt er can be set to shutter
speeds between 1 and 1/ 500 second as well as to time
exposures. The built-in synchro-flash contact enables
coupling to all flashguns and reacts to even the
shortest exposure times.
All scale settings are clearly visible f rom a bo ve .
The dOl/bl e exp os ure pr eve nti ve and the fi/III
ad v an ce lo Ck guarantee quick and safe working. The
film is advanced from frame to frame and each is
automatically counted by the frame-counter. Ther e
is no need to watch a red film window. Double ex-
posures and blanks are thus prevented. The fi lm
type indi cat or can be set to the type and speed of
the film with which the camera is loaded.

Opening and closing the camera
Span the back of the camera with you r hand,
s
li ghtly tilt in g it forward. Depr ess the opening knob
(1) and the lens w ill snap into the taking position
(illust
r. 2). If the camera is not held in the correct
position it may happen
that the s trut s do not snap
in completel y. In this case depress the front edge
of the baseboard with yo
ur fi nger (3).
To
cl ose the cam era pr ess against the upper parts
of both s trut s (2) with yo ur thumbs. Thi s mak es
the base board slide upwa rd. Th e camera can then
be conve
ni ently clo se d until the lock catch es (illustr.3).
In order to c
lo se the camera in the taking p os ition
the upper
parts of the st rut s (2) are pressed down
wi th the index fingers a ne t clo se d with the other
fingers.

Prior to the exposure
the distance between camera and subject, the
diaphragm
and the exposure time must be correctly
set.
The distallce
The subject distance is determined by means of the
built-in rangefinder. Looking through the eyepiece
(9) of the combined view
and rangefinder, you see
the image as it will be recorded by the camera
but
with a light, rectangular portion in its centre.
In this centre the outlines of the subject will appear
doubled (illustr. 4).
By turning the milled ring (see
arrow 6 in illustr. 6) with the middle finger of the
left
hand these double outlines in the centre of the
measuring field are brought to coincidence.
The
best objects for obtaining accurate focus are sharp-
ly defined vertical lines, such as the edge of a
house, a telegraph pole or a tree. (illustr. 5). As
soon as the contours coincide the lens
is accurately
focused
at the correct subject distance required.
The measured distance may be read off from the
distance setting mark (5)
on the scale of the lens
mount (4).

Exposure time
The exposure time is set by turning the milled
front ring (13).
The black stroke engraved on this
ring must be exactly opposite the figure required
on the exposure time scale (illustr. 6).
The figures
engraved on this scale indicate fractions of a second
("50" is 1/ 50 sec. etc.). With the setting "B" the
shutter remains open as long as the release knob
(15)
is depressed (see page 16). When set to
1/ 500 second a slight resistance is felt which is due
to
an additional spring needed for this fastest speed.
The shutter is tensioned by pushing the cocking
lever (14) in the direction of the distance setting
mark (5). It
is immaterial whether the shutter speed
is set prior to tensioning or after it, with the ex-
ception of the shutter speed of 1/ 500 sec. when the
exposure time must be set prior to tensioning the
shutter.
Diaphragm
Turn the milled ring (11) until the triangular
diaphragm setting mark (12)
is opposite the stop
figure required (illustr. 7).

The interdependence of the settings
Subj ec t di s tan ce and diaphragm .
When the lens is focused at some de fin ite subject
dista nce it yields a sharp pi cture not only of the
subject
at this distance bu t also of those objects
that are nearer to the camera or further away fr om
it.
Thi s zone of sha rp definition is called the depth
of field. It is rather small when th e di aph r agm is
fully open
(f :3.5) but increases gradually the more
the lens is stopped down. Thu s : the sma ll er the
stop, the greater the depth of field.
The
depth of field for any given lens aperture and
distance can be read off from th e depth-of-field
ring (10). Diap hr agm figures will be found on the
ri ght and l eft side of the distance sett ing mark (5).
Th e figur es on the distance scale (4) opposite these
stop figures indicate
the extension of the depth of
field.
Th e strokes with out figur es be side the
triang ul ar mark indicate the depth of field at stop 4
and the s trok es between 8 and 16 that for stop 11.
