THE FINDER
HOOD
To open
the
ffnder
hood,
depress
thelocking
pin(27);the
hood will then open automatically.For critically sharp
focusing,
swing
up the focusing
magnifter
(12) which is
fftted
inside
thefront of theffnder
hood
(1).To close
the
hood,
ffrst fold backthe magnifter,
and thenthe front of
thehood
itself.ln this
waytheffnder

The special
feature
of theIKoFLEx is its reflex
viewing
system,
by whichtheviewing
lensshows
an exact
replica
of the subject
to be taken.This viewing lens,
whichhas
the samefocal length and speed
as the taking lens,
projects,
via an inclined
mirror, a brilliant upright image
on to a ground glassscreen.
The ftnal picture will be
depictedsharply on the ftlm when it appearssharply
focused
on the screen.
On account of the high light-

transmission of the viewffnder system, the ground glass
is evenly illuminated right into the corners, so that the
franring is indicated exactly and the deftnition can be
judged rvith precision.
For focusing, turn the focusing knob (23); by turning
through 130o all distance settingsfrom 3 feet to inftnity
(-) can be covered.
As the focusing knob is turned, ob-
jects lying at varying distances
from the camera can be
seen
coming into sharp focus one after another. Thanks
to the ground glass
screen
focusingsystem,
the IKoFLE x
makesit easy
to find the critical point of sharpness.
Even
when the diaphragm of the taking lens is stoppeddown,

To facilitatereally critical focusing,
the magnifter

APERTU
I{E SETTINC
Lever (18) is used for setting the diaphragm to the cor-
rect lens aperture, which can be read off from the little
window (8). The larger the aperture ftgure, the smaller
isthe actualdiaphragm opening,which necessitates
longer
exposuretimes but also provides a larger depth-of-fteld
zone. "stopping dorvn" (making the lens aperture smal-
ler) will extend the zone of sharp deftnition further.
However, you should avoid stopping down to such an
extent that over-long exposuretimes become necessary,
for rvhichthe canlera can no longer be safely employed
without tripod. Since
the focusing
screen
of the IKOFLEX
perntits continuous focusing control, it is better to use
shorter exposure
times with larger
lens
apertures.

THE ZEISS IKON CABLE RELEASE
isequippedwith
a plunger catch, making longer time exposures much
more convenient to take. The cable release is screwed
into the thread (Z) on the camera body. For all instan-
taneous and short time exposures, press the small plate
"8" towards the sleevettC" and turn it slightly, where-
upon it will remain in this position. For longer time ex-
posures the plate
"B" shouldnot be
pressed against
ttCt'. In this case
a gentle pressure
on the plunger
tt
A" will lock it in
the depressed
po-
sition until a se-
cond pressure on
plate "B" releases
it. This plunger
catch allows time
exposures
of any
duration to be
madewithouthav-
ing to keep the

RED
DOT SETT'ING
One way of beneftting
from the large depth of fteld
provided
by small taking lensapertures
can be parti-
cularly usefulwhen the lighting conditions
are good.
By
setting
thediaphragmsetting
lever(18) andthefocusing
knob(23)to the red dots,
i.e.,
at approximately
25feet
and between
f/8 andf/11, everything
beyond
approxi-
mately 13 feet will be rendered
sharply without further
focusing.
Framingand composition
can be done
on the
ground
glass
screen,
whilstfast actionshots
will bemade
much
easier
by using
the
direct
vision
frame
ftnder.
Using
a ftlmrated
at l7/1}o DIN (16
ASA), an exposure
time
of l/soo
sec.
will be correct
if thelighting conditions
are
excellent;
use l/roosec.
if the light is only reasonably
good,
and 1/z;

if it is ratherpoor.

LOADINC THE CAMERA
Before loading the camera, ffrst make sure that the
automatic ftlm lock is released.
It will be unlod<ed
if the
last ftlm used has already been advanced beyond the
twelfth frame No. 12 showing in the frame counter (4),
as then the film rvind knob (5) can be turned indeftnitely
without encounteringfurther resistance.
lf
, for sornereasons, the ftlm lock is still engaged, the
ftlm rvind knob must be rvound on until the ftg. 12 has
passed the frame counter window. To do this, tension
the shutter, release
it and while keeping the release
knob
depressed
turn the fflm wind knob until frg.12 appears
in the frame counter window. As soon as the ftg. 12 has
passedthe rvindow, the ftlm lock will be automatically
released.
Open the canrera back by pushing the locking catch (26)
in the direction of the arrow; then hinge the back down-
wards and pull out the upper ftlm spool holder (21),
turningit so
that
it islocked
in the
rvithdrawn posi-
tion. The empty
take-up spool is
theninserted

the upper spool clrartrber
so that the prot)g of the ftlnl
wind knob (5) engages
the slot in the spool.
Turn back
the upper {ilnr spool holder (21) and allow the pivot to
snap
into the holeof the spool,
which can now be rotated
easily
by meansof the ftlm wind knob (5).
In exactly the same
wtY, the new spoolof ftlm is insertecl
into the lorver spool chamber (25); tear the seal and
thread the tongue of the backing paper into the long slit
cf the enrpty take-up spool by pulling it across the ftlm
rvindow.Turn ftlm wind knob (5) until the paper is tight
and winds evenly on to the tal<e-up
spool.
Then close
the
canlera back and wind on the {ilm until the figure 1
appears in the ftlm window (28). The camera is no\v
correctly loaded and ready for the ftrst exposure.
Close
the ftlm windorv, depress the notched wheel (6) of the
frame counter (4) and turn it in an anti-clockwise
direc-
tion until it locks.
The window of the frame counterwill
now also indicate
No. 1; from now on it is only neces-
saryto consult
the frantecotttrter.
