ThC  IKOFLEX FAVORIT
made bv ZEISS IKON AG. STUTTGART is a twin-lens
 mirror ieflex camera with fullv automatic frame counter
 mechanism, built-in photoeleitric exposure meter and
 exposure value-setting of the shutter, taking twelve
 2LlsX2rlq ins. exposures on 120 roll fflm. Its viewing
lens renders an unusually brilliant and sharply deffned
image of the subject on a ground-glass screen equipped
 with a light-concentrating grid. The readings derived
from the exposure meter can be read off from a scale
 clearly visible on the upper part of this ground-glass
screen. Since both the viewing and the taking lenses,
which have equal focal lengths"and speeds, are ioupled,
the IKOFLEX FAVORIT can be quickly adjusted with one
hand. This permits rapid operation and u.iurute focusing,
allowing- the photographer to concentrate on the compo-
sition of the picture. Both the tal<ing and viewing lins
have a hard anti-reflection coating io prevent iniernal
reflections and flares. The taking leni is excellently colour-
correc-ted, ensuring colour phot"ographs as well as black-
and-white pictures of superb deffnition. The thoroughly
reliable giound-glass focusing mechanism allows"tKe
quality of the high-speed lens to be utilized to the full.
The IKOFLEX FAVORIT is equipped with a Synchro-
Compur Shutter which is fully-svnchronised and has a
self-timer as well as the novel exposure value setting.
However, stops and shutter speeds^can be set also indE-
pendently of the exposure vilue setting. The operation
of the frame counter mechanism arid the tensionins of
the shutter are carried out automatically. Furtherm"ore,
double exposures and blanks are preuenied by an auto-                                                                        'matic interlocking mechanism.
leforc inserting thc ffrst film into your IKOFLEX FAVORIT,the operations descrrbed in this booklet should be practised carefully.
If you. takc thi-s trouble, you will be rervarded with good pictures
from the very beginning and your IKOFLEX FAVORIT-will  be
a never-cnding source of pleasure to you.

OPENINC AND CLOSINC
THE FINDER HOOD

To open the ftnder hood, depress the locking pin (26);
the hood will then open automatically. For critically
sharp focusing of the ground-glass screen image within
the ftnder hood (1), srving up the focusing magnifier (10)
which is {itted inside the front of the ftnder hood (1). To
close the hood, first fold back the magnifter, and then
the front of the hood itself. In this way the ftnder hood
will fold up flat automatically.


FOCUSING
The special feature of the IKoFLEX is its reflex viewing
system, by whi& the viewing lens shows an exact replica
of the subject to be taken. This viewing lens, which has
the same speed and focal length as the taking lens, pro-
jects, via an inclined mirror, a brillant upright image on
to a ground-glass screen. The actual picture will be
sharply depicted on the ftlm when it appears sharply
focused on the screen. On account of the very high light-



                  www.butkus.us

transmission of the viewfinder system, the ground-glass
 screen is evenly illuminated right up into the corners, so
 that the framing and composition is indi'cated exactiy
and the definition can be judged with precision.
For focusing, the focdsing knob (22) should be turned.
By turning this knob through 130o all distance settings
from 3 feet to oo (inftnity) can be covered. A$'the focus-
ing knob is turned, subjects lying at varying distances
frorr the camera can be seen coming into sharp focus one
after another. Thanks to this focusing system, the
I Ko F LE X rnakes it easy to ftnd the critical point of
sharpness. Even when the diaphragm of the taking lens is
stopped down, the image depicted by the viewing lens

will always retain its full brightness, thus  f acilitating
accurate focusing. On the other hand, the depth of ffeld
of the stopped-down taking lens can easily be read off
from the depth-of -fteld scale (21). In order to make
really criti,cal focusing easier, the focusing magnifter (10)
should be swung into position by pressing gently against
the central panel of the finder-hood front (11). Vhen
using the magnifier, the eye must be brought as close as
possible and directly above the centre of the magnifter.
To assist the avoidance of converging lines and other
distortions, the ground-glass screen is divided into

squares.

EXPOSURE COMPUTER

The rotatable computer disc of the photo-electric expo--
sure meter (23) i; incorporated in the focusing knob
(22). It may be used for computing the relationships be-
tween the diaphragm settings and the shutter spee4s.
First set the speeil6f the film in use on the inner disc by
means of the little l.tg. The disc can be set for film                -DINspeeds rated either in      or ASA, according to the
instructions on the ftlm packet. In the example used for
our illustration below, the computations were based on a
ftlm speed of t 5110" DIN (10 ASA).
Before making an exposure/ take a reading from the in-
dicator on the scale on the focusing screen. If the expo-                                             tt7ttsure meter shows, for instance,     (see ill. on page 7)
the rhomboid mark on the computer disc should be set
so that its outer point indicates "7".
Now pro,ceed by reading off the values for f/number and
shutter speed from the scales calibrated in f/nos. and
seconds. The illustration below shows that for  f 14 an
exposure time of Ll+ second is required; for  f /5.6 rlz se-

lf, at any particular setting, the outer point of the rhorn-
 Uoia -u.k 0  is pointing to any ffgurb between 12 and16 (white ftgurei on blick ground), the -green -ffgures
 appearing oti the seconds scall should not be used under
 ani circumstances. Here an example  ' If ihe camera is loaded with a ftlm rated at 24110o DtrN
 (80 ASA) and 1f the exposure meter on the focusing
 screen scale shows 75', an exposure can be rnade only at
 fl16 and llsoo sec. or [lZZ and rlzro second. The green
 fisures 30 and 60 which are also visible must not be
ur.d, as they will result in gross over-exposure.
Basic rule
If the outer point of the rhomboid mark 0 points to
figures between 2 and 1 1 (black figures on whiteground),
all values shown on the seconds scale can be used.
If the rhomboid mark Q with its outer point indicates
figures between 12 and 16 (white figures on black
ground), the green whole second values should not be
used under any circumstances.
For exposures with filters the engraved fflter  f actor, e. g.
2 X (yellow filter) should be set against the figure indi-
cated by the ex-     \
posure meter in-
stead against the
outer point of the
rhomboid mark Q   .

EXPOSURE METER AND EXPOSURE
VALUE SETTII{G

The exposure meter is built into the viewftnder head.
When the cover flap (13) is opened-     a pointer on the scaleon the ground-glass- scfeen  indicates a figure, which,
when tra-nsferred to the computer disc, serves to deter-
mine the diaphragm stop-theand shutter speed to be used. If you want to employ     exposure-the-   value setting-, t!t..*for.r.. value indicited by     inner point of the
rhomboid mark 0  should be transferred to the exposure
value setting ring (15) by rotating one of the two setting
wheels (6) or (7i and at the same time holding back the
other one (the example on page 10 shows the exposure
value 6 marked in red).
Now it will be possible to use any other combination of
 aperture and shutter speed within the range of the
 exposu.e value indicated, by turning the setting wheel (6).
The window (14) will then show the same combinations
which can be read off  , from the computer disc (23).

APERTURE SETTING

  If the exposure value setting is not used the stop required
 can be set by operating the diaphragm setting wheel (Z).
 The individual stops a.re marked in black ftgures which
 can be read off from the window (14).The larger the
 figure appearing in the window the smaller is the actual
 stop, which necessitates longer exposure tim,es but also
 provides a larger depth-of-ffeld zone. Stopping down the

 however, you should not make the lens aperture so small
 that over-long exposure times become necessaryf for
which the camera can no longer be safely employed
 without a tripod. Since the focusing screen of the
IKoFLEX permits continuous focusing control,  it is more
advantageous to
use shorter expo-
sure times  r,vith
Iarger apertures.

SHUTTER

The TKOFLEX FAVORIT is equipped with a fully syn-
 chronised Synchro-Compur Shutter with self-timer and
an exposure value setting ring. The shutter speeds from
 1/roo sec. to 1 second can be set by means of the setting
wheel (6) and can be read off from the window (14) in
red ligures. The red figures appearing in the window
represent fractions of seconds; e.g. 4:  r/nsec., 125 :
 1/rzr sec., etc.
 If the required exposure time exceeds 1 second, the
 shutter should be set to "8" . To this purpose the key (9)
 should be pulled downwards and held in this position
while the shutter speed setting wheel (6) is turned until
the letter "8" appears in the centre of tire window (14).
\When set to "8" the shutter renrains open as long as the
shutter release (8) is depressed.
The key (9) is a safety measure to prevent incorrect
exposures by an unintentional "B"-setting of the shutter
when the exposure value setting ring is used. If the
shutter is set to a shutter speed other than "B" the
key (9) willspring
back automati-
cally into its inter-
locking position.

RED DOT SETTING
This is a useful method of beneffting from the great
depth of fteld provided by small apertures of the taking
lens when the lighting conditions are good. By setting
the diaphragm settingwheel (7) to between {18 and f 111
and the focusing knob (22) to approx. 25 feet (both
settings are marked by red dots), everything beyond
approx. 13 feet will be rendered sharply without further
focusing. Framing and ,composition can be done on the
ground-glass screen in the usual way, whilst fast action
shots should be made by using the frame ftnder. Using
a film rated at 17110" DIN (17 ASA) an exposure time
of r/zso sec. will be correct when the lighting conditions
are excellent; use l/rzs sec. wheu the light is only
                                reasonably good
                                  and 1/rso sec. when

                   of the hood (12) together
with the eyepiec e (25) at the rear can then be used as a
frame finder. Correct framing is ensured when the
edges of the eyepiece coincide with the inner edges
of the front frame. Focusing can either be done in
advance on the ground-glass screen or by using the "red
clot setting". The frame ffnder is particul arly suitable
for taking sports events and rapid action snapshots.

LOADING THE CAMERA

Before loading the cam efat first make sure that the auto-
matic film loJk is disengaged. It will always be unlocked
rvhen the last film used has already been advanced
beyond the twelfth frame (No._ 12 showi.ng in the frame
coirnter), as then the film wind kn-ob (5) can be turned
indeftnitely without en,countering further resistance.
To open the camera back fold up the locking -b-ut (27)and i.trn it to the left. Pull out the spool holder (20)
and lock it by a slight rotation. An empty take-up spool
is then insert-ed into the fflm chamber in such a way that
the prong of the film wind knob (5) engages the slot in
the ipool Turn back the spgol holder (20) ?nd allow the
pivoito snap into the holebf the spool, which can nbw be

TAKING PICTURES

\X/hen taking pictures with the hand-held IKoFLEX, the
camera should hang from its carrying strap/ adjusted
to a comfortable length for viewing the subject in the
 finder hood. The aperture and shutter speed required
should be read off from the exposure computer disc (23)
and can be set either singly or as an exposure value by
means of the setting wheels (6) and (7) and transferred
to the exposure value setting ring (15). Then both
thurnb and foreftnger should be used to operate the
focusing knob (22) for the distance setting. Make sure
that the fflm wind knob (5) has been wound on until it
has stopped, by which means the shutter has also been
tensioned. Compose the picture and focus it sharply on
the ground-glass scr€€n; the grid pattern will help you
in aligning both the vertical and the horizontal lines of
the subject. As soon as the screen image looks perfect,
make the exposure by giving a gentle pressure on the
release knob (8) which must be unfolded, of course,
beforehand. NEVER jerk the knob abruptly! Although
the release knob (8) must be depressed as far as it wlll
go, the camera must be kept absolutely steady at the
moment of exposure. After every exposure/ the fflm
wind knob (5) should be turned until it stops in order
to be ready for the next shot.
For exposures longer than 1/so second a tripod should
be used. It should be screwed into the tripod bush (28)
at the base of the IKoFLEX-FAVoRrT.  lt is advisable
to use a cable release but it should be borne in mind
that the body shutter release (8) must be folded out
before using the cable release.

FILM \)rII.JD LOCK  I
FILM TYPE INDICATOR AND FRAME
COUNTER MECHANISM

 After each exposure. the film must be advanced by
 turning the film wind knob (5) until it comes to a stop.
There is no need to watch the numbers in the frame
 counter; the ftlm can be advanced even in the dark. The
number of the frame ready for exposure appears auto-
 matically in the window of the frame counter (4). By
advancing the film the shutter also will be tensioned.
The ftlm can be wound on only after the shutter has
been released and the next exposure cannot be made
until the ftlm has been advanced until it stops. Double
exposures or blanks are therefore eliminated completely.

UNLOADING THE CAMERA

 After the twelfth exposure, the ftlm wind lock is auto-
matically disengaged. Then the fihn wind knob (5)
should be turned until the fflm is wound up completely.
Open the camera back in subdued light (never in ftrll
sunlight). Seal the fflm in the ftlm holder, pull out the
upper ftlm spool holder (20) and relrove the spool from
the txoFLEx. Straight away remove the empty feeding
spool from the lower spool chamber and replace it in
the upper one. Once again, care must be taken to ensure
that the prong of the fflm wind knob (5) engages the slot
in the spool. Now a new ftlm can be inserted into the
camera.
 If, for some reason or other, a ffLn must be removed
from the camera before the 12th frame has been
exposed, a new ftlm should not be inserted before the
frame counter mechanism has been adjusted to its ffnal
positior.r beyond the figure 12. This can be achieved in
the followin€f way, leave the camera open after the
cxposed fflm has been removed and operate the ftlm
wind knob (5) and the body shutter release (S)
alternately until the fflm wind knob can be rotated
indeftnitely rvithout encountering further resistance.
If the camera back has beer-r closed before the frai-r,c
counter mechanism has been set to its end position, the
frame counter will be disengaged from the ftlm transport
mechanism. To re-engage it proceed as described on
page 19.

SEI F-TIMER ("V" SETTING)

For taking pictures with the self-timer, the shutter should
be tensioned and the synchro-lever (19) set to the letter
"V". The delayed action mechanism starts to operate
when the shutter release (8) is depressed. After approxi-
mately 10 seconds, the shutter will be automatically
released, the shutter speed being that which was set
beforehand. \While releasing the shutter the synchro-
lever (19) springs back to the "X" position automati-
callv; it should never be pushed back by hand  I
The use of the self-timei is particulariy recommended
in all cases when the shutter speed is slower than 1/so se-
cond, as it acts as a safeguard against camera shake.
\7hile the delayed action mechanism is running the
camera can be ftrmly held with both hands, so that even
longer exposure times can be employed successfully
without a tripod provided that the photographer  does
not move during the actual exposure.
The self-timer clnnot operate when the shutter is set to
ttBtt (time expo-
sure) or when the
synchro-lever (19)
is set to the "M"   t'X"of      marks.

FLASHLIGHT EXPOSURES
The IKOFLEX can be used for exposures with both
                                                                                                                                                   ? expendable flashbulbs and electronic flash in such a way
 that the flash is ffred by the shutter at the most effective
moment. To take flash exposures slip the plug of the flash-
lead over the flash contact (1S). The fully synchronised     I
                                                                         ?Synchro-Compur Shutter not only permits the ftring of  .
flashes at the exact moment the shutter is wide open
("V" and "X" setting), but also, when set to pre-ignition
 (tt Mtt setting)/ a fraction of a second before the shutter
is fully opened.

FLASH PICTURES \rITH INSTANTA-
NEOUS FLASH ("X" SETTING)
$7hen using an electronic flash unit the synchro-lever          i
(19) must be set to "X". All shutter speeds between
1 second and 1/;oo second may then be used. Releasing
the shutter should be done in the usual way.
\ilUhen exposures are made with the self-timer (ttVtt             t
setting) the flash will be ffred when the delayed action
mechanism has run off and the shutter is wide open,
in the same way as if the "X" setting had been used.
