Loading and unloading
Inserting the film
(Do not carry out in direct sunlight!)
Pu ll rewind knob 21 upwards until the camera back is released. Then slip
the film leader which projects from the cassette into the slot in take-up
spool
29 and engage with one of the perforations to the tooth in the slot.
(If the slot is not visible , rotate the spool by turning milled ring 30.)
Next pull the cassette across the film track and drop into film compart-
ment 23, rewind knob 21 again being pulled upwards as far as it will go.
Now push the rewind knob right
down into the camera.
Rotate the take-up
spool by turning milled ring 30 until the perforations
at both edges
of the film are engaged by the sprockets of transport
roller 28.
Lift up the eyecup, close the camera back and press down until an
audible click indicates that it is firmly closed. Now operate rapid
advance lever
18 and release button 17 until the number "1 " appears
below the red index in film counter27. As soon as a number is visible in the
film
counter window , this indicates that there is a film in the camera
(loading
control). When the film counter moves on, the film has been
advanced (film transport control). Th'e film counter always indicates the
number of frames that have already been exposed.
Selling the film speed
Set the speed rating on the camera immediately the film has been
inserted
or check the speed that is already set. The film speed rating
in DIN
or ASA is given either on the film packing or in the instructions
5

for use. Turn milled ring 8 until the appropriate number is opposite the
red
triangle below window 7.
If the number given is not engraved on the scale, set at a suitable
intermediate rating.
Film-in-use disc
This serves merely as a memory aid and does not influence the camera
action.
When
disc 12 is turned the symbols click into position above setting
dot 13 . They present:
colour reversal film for daylight exposures
black-and-white film
colour negative film
colour reversal film for flash exposures
infra-red film
colour reversal film for artificial light.

Removing the film
After exposing the last frame (the film counter indicates the number
corresponding to the number of frames on the film), do not advance
lever 18 but rewind the film. Press down button 24 to release the rewind
locking mechanism and turn rewind
crank 21 clockwise until the film
counter indicates the initial position and a slight resistance is felt. Only
now open the camera back by pulling up the rewind knob and remove the
film cassette. Always keep the take-up spool and film
guide track clean!
Focusing
Look through the viewfinder and turn setting ring 4 until the split-imag es
visible in the centre of the viewfinder are exactly aligned or, if the subject
has no distinct lines, use the ground class screen to focus the picture .
The focused
distance is indicated on scale 5 at setting mark 6.
If the viewfinder is blocked out , move the small lever 15 to the right
over the red dot.
If the viewfinder image is darkened, open the lens diaphragm by de-
pressing button
9. The pre-set aperture is retained.

Aperture and depth of field
Pre-set the aperture by turning milled ring 3. The f/ number required must
be
opposite setting mark 6. The aperture depends on the depth of field
dictated by the type of subject. The smaller the f/ number the larger the
lens aperture and the smaller the depth of field. The depth of field
indicated by the pre-set aperture can be read direct from the depth of
field scale 6 on the lens.
It covers the range from the distance indicated opposite the f/ number
on the left to the distance opposite the same f/ number on the right.
The depth of field can also be checked on the ground glass screen in the
viewfinder. By pressing down button 9 the
diaphragm is closed to the
pre-set value and thus the aperture
or distance can be adjusted exactly
as required. When button 9 is pressed down again, the diaphragm
returns to full lens aperture. It is automatically closed down to the pre-set
aperture when the
shutter is released. Focusing is also possible with
the depth
of field scale (recommended for snapshots). Determine the
depth of field required with the aid of scale 6 and set the indicated
f/ number opposite setting mark 6 by turning ring 3.
Exact data are given in the enclosed
booklet containing the depth of
field tables.
Setting the shutter speed
Turn disc 19 until the shutter speed required for the exposure clicks
into position opposite setting dot 20 . Intermediate speeds must not be
used.
The shutter speed
depends on the lighting conditions and the rate
at which the
subject is moving. The faster the movement, the shorter the
exposure time. The numbers on ring
20 denote fractions of a second
(60 = ' 160 sec.). The orange number s indicate that a tripod should be
used.
8

When set at " 8 ", the shutter remains open as long as the release
button is depressed .
Shutter speed and aperture are inter-dependent. The faster the shutte r
speed,
the larger the apertu re and vice-versa. The exact values can be
determined with the built-in expClsure meter.
Exposure measurement
To switch on the exposure meter, lever 18 must be swung out and dia-
phragm button 9 depressed. Now pre-select shutter speeds.
Sight the subject with the camera held in a horizontal position , even
if the
exposure is to be made with the camera in the vertical holding
position . Turn aperture ring 3 until the exposure meter needle in the
viewfinder or on the camera body below window 14 is positioned exactly
in the centre of the triangle .
The aperture is indicated at the top of the viewfinder. If a definite aperture
is dictated by the type of subject, pr e-sele ct this aperture and turn shutter
speed disc 19 until the exposure meter needle COincides with the centre
of the triangle. Only a click -in shutter speed must be used, otherwise
adjust the aperture setting .
If the indicator below window 14 is used for exposure measurement , for
instance , when using a tr ipod, the viewfinder eyepiece must be covered ,
in
order to keep disturbing stray light from enter ing and falling on the
photo-resistor . To do this , move lever 15 to the left (red dot becomes
visible) .

The exposure meter
Light metering is through the lens (inside metering). The light falls on
two CdS photo-resistors. These regulate the battery power in relation to
the incident light. The exposure meter in the Icarex 35 S has standard
calibration. It provides correct exposure for average conditions.
Correction is necessary:
Against-the-light exposures, dark subjects against a bright background
or subjects of low contrast (overcast sky -snow landscapes) -
after measurement open the aperture ' (, to 1 stop . Subjects of high
contrast , in particular , very bright subjects against dark backgrounds-
after measurement close the aperture , (, to 1 stop.
Battery
The " Mallory PX 13" provided in the camera to operate the exposure
meter
will last about one year under normal use. Ax extremely low
temperatures below -10
0
C, use type " Mallory PX 625 ".
When testing in the open at average brightness with the camera set at
'(60 sec., the battery is still in working order as long as the exposure
meter needle moves across the entire
acceptance field on turning the
aperture ring
after the diaphragm button has been depressed and the
rapid lever swung out. If this is not the case, the battery must be changed.
It is accomodated underneath cover 33 which is removed. by turning to
the left. When inserting a new battery take care that it is poled to match
the signs on the
cover . New batteries are obtainable from photographic
dealers.
The exposure meter should be switched off when the camera is not in
use
for longer periods. It is switched off when the diaphragm button
projects or the rapid advance lever is pushed in.
The exposure
When taking a shot press down release button 17 rapidly and smoothly.
The mirror swings up, the diaphragm closes down to the pre-set lens
aperture and the focal-plane shutter travels at the pre-set speed.
Immediately afterwards, the mirror returns to its position for viewfinder
focusing. When the diaphragm button in depressed, however , the dia-
phragm always remains at the pre-set aperture
after release and
tensioning.
