l. The film spool
The Ikoflex I takes pictures 2rlt" squ,are (6X6 cm), and is loaded with the normal
120 size rollfilm. In the lkoflex, this film gives 12 exposures in t}l.e 2r/r" square
format.
The spools of film are light-tight when the end of the backing paper is stud<
down, but it is always advisable to Ioad and unload the camera in diffused day-
light or else in the shade, Direct sunlight should not be allowed to strike the
spools. Always wind the film and codr the shutter first before pressing the release
button.
ll. loqding rhe comercl
1. The knob (18) is moved in the direction
of the arrow and the camera back simul-
taneously pulled open.
2. The knob attached to the pin holding the
spool in the lower or feed chamber (23)
is now pulled out and turned slightly to
lock it in the outer position. The fullView original page 6Page 7 · Read text
spool of film is placed on the right-hand
(fixed) pin in the lower or receiving spool
chamber: the pointed end of the backing
paper must point towards the other spool
chamber, and the black side of the paper
must face inwards. The knob (23) is
then turned back, and the peg allowed
to enter the circular hole bored in the
core of the full spool. The spool is now
held firmly in place.
3. The paper strip holding down the point-
ed end of the backing paper is now bro-
ken, and the backing paper itself pulled
out over the open back of the camera
until its pointed end can be pushed
through the larger slot of the empty spool
in the upper chamber.
4. By turning the film winding knob (5)
round once or twice, the paper is tight-
ened and a little of it wound on to the

spool. The paper must run evenly bet-
ween the flanges of the spool: should it
chafe or rub the flanges, it must be loos-
ened and made to run flat between
them.
5. The camera is then closed by pressinq
the hinged back firmly against the main
body. The lock must snap audibly into
place.
6. The cover over the red window (22) in
the back of the camera is now slid away,
and the film winding knob (5) turned for-
ward continuously until a hand appears
in the red window (22). This is a war-
ning sign, and just after it the number'I'
will appear. As soon as the number 'l'
appears in the red window the first
section of film has been wound into the
focal plane of the camera and is readv
for exposure.View original page 8Page 9 · Read text
The red window is now covered once
more with the slide, in order to avoid
any risk of fogging a panchromatic film.
lll. Unlooding rhe ccrmercr
1. After the last (i. e. twelfth) exposure has
been made, the film winding knob (5) is
turned continuously f orward until the
end of the backing paper has moved past
the red window (22).
2. The camera back is then opened as des-
cribed on page 6, and the end of the
backing paper on the exposed film spool
sealed down firmly with the gumstrip
provided. The knob (19) is now pulled
outwards, locked in the outer position by
turning it slightly, and the exposed spool
lifted f rom its holder.
3. The knob (23) in the lower spool chamber
is then pulled out and held in the outer

position by turning it slightly. The empty
spool from which the exposed film has
been unwound, is then removed and pla-
ced in the upper spool chamber. One
end of the spool has a circular hole and
the other a circular hole with a cross-
slot: the slot must be placed on the
same side as the film winding knob and
engagecl with the metal dogs on the
winding knob peg (25) so that -the spool
is carried round with the knob. The
knob ( 19) is then turned slightly back,
and will spring inwards and hold the
empty spool firmly in position. The
camera can then be loaded with a new
spool of film.

the finder hood. That part of the subject
which is in sharp focus is shown by the
depth of focus scale (20) placed next to the
focusing control knob. As may be seen in
the illustration, at f ltt ob j ects at all dist-
ances between about 6 and 15 feet will be
sharp when the focusing distance is I feet.
1 . Move the lodcing button (17) to the left,
as shown, and the finder hood will
spring automatically into position for use.
) In use, the camera is slung round the
ned<, and adjusted to a convenient height
by altering the length of the strap used.
On glancing down into the finder hood,
an upright picture of the scene before
the camera will appear. This picture is
reversed left to right, as is the case with
all reflex cameras.

In order to obtain critical focus, particularly
when using large lens apertures, it is praeti-
cal to use the focusing magnifier (14).
3. After pushing down the right-hancl side
panel (1) of the finder hood, the built-in
magnifier is raised with the forefinger of
the right hand by means of the lug on
its side.
When focusing, the eye must be directly
over the centre of the magnifier.

Prevention of double exposures
It.is idpossible to expose one section of the film twice, since the shutter will not
operate until the winding knob (5) has been turned forward, and a new,section of
film wound into the focal plane of the camera.

the disc can be seen, the film has been'wound on,'jnd'.eteurirrq th" shutter will

The lens operture
The lens aperture is adjusted by moving the Iever (9) to one side or the other.
The apertuie numbers are indicated on the scale seen through the window (11).
The larger the aperture number, the smaller the size of the aperture of the lens'
and the gireater the depth of focus-but also, the larger the aperture number, the
longer must be the exposure under the same light condition.
Seffing the shutters

cable release may alternatively be used; and it is screwld into the nipple of the button (3).
Important: when the shutter has been set, do not be ctrange from a srow shutter
speed to its highest speed, since this would put too much of a strain on the inter_ nal mechanism.
