Loading and unloading
(Not to be carried out in direct sunlight)
Pull out the rewind knob 15 until the camera back springs open. Then
slip the end of the film leader which projects from the cassette under
one of the red holding prongs, pull the cassette across the film track
and insert  it in the film cassette chamber 24, whereby the rewind knob 15
must again be pulled out as far as it will go. lt can now be pushed
down into the camera again to its original position. (lf necessary, rotate
slightly while pushing.) The take-up spool must now be rotated by
turning the red milled ring until the perforations at both edges of the
film are engaged by the teeth on the transport sprocket 27. Now close
the camera back and press firmly until it locks with a click. Operate
the rapid advance lever 22 and the shutter release 12 alternately until
the number "1" appears under the mark of the frame counter 29. As soon
as a number is visible in the frame counter window, this indicates 'ihat
there is a film in the camera (loading control). lf the frame counter
moves on, the film has been advanced (film transport control). The
frame counter always indicates the number of frames that have been
exposed. After exposing the last frame -  the frame counter indicates
the number corresponding to the number of frames on the loaded i'ilm -do not tension with the rapid advance lever but rewind the film.

counter has reached its initial position and a slight resistance is felt.
The film has detached itself from the take-up spool. 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!

Setting the film speed
lmmediately after loading the film set the film speed on the camera or
check the speed that has already been set. The film speed in DIN or
ASA is given on the film packing or in the accompanying instructions
for use. Push button 19 in the direction of arrow. Turn the setting disc 16
until the film speed required is engaged at the setting mark 18.

 Focusing
 Should the viewfinder eyepiece be locked, turn ring 26.
 Look through the viewfinder and sight the subject, if possible, oo a
 vertical or horizontal edge or line so that it runs exactly through the
 centre of the finder. By turning the focusing ring 8, the line which
 appears distorted in the central diagonal split-image rangefinder  is
 straightened. The correct distance has now been found, whereby the
 unsharp line on the ground-glass screen and in the microprism spot is
 sharply defined at the same time.
 The distance set can be seen on the scate I at the orange setting
 mark 10.
 With subjects where there is no possibility of focusing on a straight line,
 the focusing can be done with the microprism spot or the ground-glass
 screen.
We recommend that anybody wearing spectacles should screw the
 appropriate correction lens (see .list of accessories) into the viewfinder
 eyep iece.

Aperture and depth-of-field
Pre-select the aperture by turning the setting ring 7. The f/number
required must be opposite the setting mark 10. The setting of the aper-
ture depends on the depth-of{ield required. The smaller the f/number,
the larger the lens aperture and the smaller the depth-of-field. The
depth-of-field resulting from the choice of aperture can be read direct
from the depth-of-field scale to the left and right of the setting mark 10.
It covers the range from the distance opposite the set 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 view-
finder. By pressing the stop-down pin 3, the diaphragm is stopped down
to the pre-selected value and thus makes  it possible to adjust the aper-
ture or distance exactly to the requirements of the photograph to be
taken. When the stop-down pin 3 is pressed again, the diaphragm springs
back to full aperture. lt is then automatically stopped down to the pre-
selected value when the shutter is released.
Focusing is also possible with the depth-of-field scale (recommended
for snap-shots). Fix the desired depth-of{ield with ring 8 and scale 10
and set the indicated f/number opposite setting mark with the setting
ring 7.
Exact data on depth-of-field are given in the enclosed list of tables.

                             www.butkus.us

Setting the shutter speed
     Turn ring 14 until the shutter speed required for the exposure engages
     above setting mark 13. Intermediate speeds cannot be set.
     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 14 denote fractions of a second
      (60 :   r/eo SOC., and so on). The orange numbers indicate that a tripod
     should be used.
      Shutter speed and aperture are inter-dependent. The shorter the expo-
     sure time, the larger the aperture must be, and vice-versa. The speed-
      aperture combination is determined by the film speed, the general
      brightness and, when using colour filters, their filter factor.
    Preparations for exposure measurements
   The battery
     The Mallory type PX 625 battery inserted in the camera to operate the
     exposure meter will last for about one year with normal use.
     Hold the camera towards a light source so that the exposure meter
     needle comes to rest in about the middle of the setting triangle (see
      also the illustration of the viewfinder on page 9). Now press briefly on
     the battery test button 33. lf the needle wanders out of the setting
      triangle within 1 to 2 secs., the battery must be changed. New batteries
     are obtainable from photographic dealers.

    Changing the battery
        It is accommodated  in the battery compartment 30 under the cover 34,
     which can be removed after being turned to the left. When inserting the
    new battery, make sure that it is poled according to the signs in the
      cover.

Exposure measurement
Do not forget to set the film speed!
To operate the exposure meter, the main switch 21 must be switched
on by swinging out the rapid advance lever 22 into the working position.
When using the ZEISS lenses which can be supplied for the SL 706, the
diaphragm stop-down pin 3 must not be pressed in! (Open aperture
measurement.) With other lenses, however, the diaphragm stop-down
pin is to be pushed in before measuring. (Working aperture measure-
ment.)
After pre-selecting the shutter speed, view the subject with the camera
held horizontally, even if the exposure is to be made with the camera
in the vertical holding position. Now turn the aperture ring 7 until the
exposure meter needle in the viewfinder or under window 17 on the
camera is exactly in the centre of the triangular mark. The aperture
thus set is indicated on the lens barrel or in the viewfinder.
lf a definite aperture is required for the exposure, pre-select this aper-
ture and then turn the shutter speed ring 14 to set the exposure meter
needle in the centre of the triangle. Only a click-in shutter speed must
be used and this may mean slightly adjusting the aperture setting. On
changing to longer exposure times, a certain point will be reached,
depending on the speed of the film, which marks the lower measuring
limit of the exposure meter (referred to the completely open lens). For
example, with 21 DIN and full aperture on changing from 1/4 sec to
1/z sec, or with 24 DIN between  r/e sec and tlr sec, etc.
ln order to avoid any unintentional crossing of this limit, a red field is
pushed across the triangular mark in the viewfinder. As soon as the
red field covers the centre of the triangular mark, it is no longer pos-
sible to make adjustments.
On setting to the flash symbolwww.butkus.usand B, the exposure meter cannot be
used at all.

lf the exterior exposure meter indicator 17 is used, when using a tripod,
  for example, the viewfinder eyepiece must be covered, otherwise stray
  light can influence the exposure measurement and result in under-
 exposure. ln this case, turn the viewfinder eyepiece ring 26 to the left.
 The exposure metering has standard calibration. lt witt inoicate the
 correct exposure setting under average lighting conditions. correction
 is however necessary for against-the-light exposures, dark subjects
 against a bright background or for subjects of low contrast (overcast
 sky, snow landscapes).
 In this case, after the measurement has been taken open the aperture
 by 1/t to 1 stop. with subjects of very high contrast, especially very
 bright subjects against dark backgrounds, close the aperture by 1lz to 1
 stop after taking the initial measurement.
 In order to avoid unnecessary battery drain during long pauses between
 use, the exposure meter should be switched off.
 To do this, press back the main switch 21 into its initial position with
 the rapid advance lever.

The exposure
 when taking a shot, the release button 12 should be pressed down
 rapidly. The mirror swings up, the diaphragm closes down to the pre-set
 lens aperture and the focal-plane shutter travels at the shutter speed.
 The mirror then returns immediately to its position for viewfinder focus-
 ing and the diaphragm springs back to full lens aperture. when the
 diaphragm stop-down pin is pressed in, however, the diaphragm always
 remains at the set value, after release and tensioning.
When the shutter has been released, a warning mark appears in the
 bottom left-hand corner of the viewfinder to indicate that the camera
 must be tensioned for the next exposure. when doing this, always swing
 the rapid advance lever 22 through as far as it will go.
Exposures with the self-timer
Tension the shutter beforehand with the rapid advance lever and then
press lever 1 upwards as far as it will go. on pushing the release knob 2
in the direction indicated by the arrow, about g seconds elapse before
automatic exposure. During this time the lever returns to its initial
position.
Time exposures (shutter setting "8") are not possible with the delayed-
action mechanism.

Exposures with filters
The yellow, green, orange and red filters which are available for the
sL 706 can only be used with black-and-white film, whereas the UV,
lkolor-A, lkolor-B, skylight and coNTApoL filters can also be used with
10

colour material. The filters, with a bayonet mount fitting B 50, fit all
 lenses which are available for the SL 706. from 35-135 mm.
 The through-the-lens light metering system means that the filter factor
 is usually adjusted automatically. Only when using the more dense
 colour filters for black-and-white film is it advisable after exposure
 measurement to either open the aperture by one stop or increase the
 exposure time by one full value (corresponding to filter factor 2x).
The CONTAPOL polarizing filter
 (Filter factor 3x)
 The main purpose of this filter is to subdue or suppress annoying
 reflections from the subject being photographed, as well as for special
 individual effects, particularly with colour film, without falsifying the
 colours. Mount the GONTAPOL  in front of the lens and observe its effect
 through the viewfinder. The filter effect can be altered by turning the
 milled wheel on the front of the CONTAPOL.  lf reflections cannot be
 sufficiently subdued, alter your position until the camera points at an
 angle of about 35 degrees to the reflecting surface.
            gj\*,4Exposures with flash
Set one of the flash symbols at the setting mark 13 with the ring 14,
according to the type of flash unit which is going to be used. For
electronic flash units the flash symbol, for flashbulb guns using type AG
 bulbs the flashbulb symbol. The shutter speed in both cases is r/ro s€c.
With the setting of the flash symbol, the contact is so controlled that
the various flashbulbs and electronic flash units are fired at the correct
moment.
The flash unit itself can either be slipped into the accessory shoe 20 or
attached to the camera with a bracket screwed into the tripod socket 32.
When using flash units with an M-contact (without cable), the electrical
connection to the camera is directly via the contact in the accessory
shoe.
With units without M-contact, the flash lead is plugged into the con-
nection socket 4.
The aperture required results from the flash guide number and the
distance of the flash from the subiect
Exposures with Monocular 8x30 B
When using the Monocular 8x30 B, which can be attached in front of
the ZEISS TESSAR 2.8/50 lens with an adapter ring, the lens is stopped
down optically to a fixed smaller aperture. For this reason, the aperture
ring must be set at the largest aperture during exposure measurement.
The measurement is carried www.butkus.usout by turning the shutter speed setting
ring 14.

                                                                           11

l--





   Ghanging the lens
    The lenses are fitted to the camera by means of a thread mount. when
    removing or attaching the lens, the diaphragm stop-down pin 3 must be
     in its neutral position, in order to avoid damage to tne diaphragm stop-    down mechanism.

   Removing the fenses
    Unscrew anti-clockwise.

   Attaching the lenses
   Do not cant! Place on straight and screw in clockwise as far as it will go.
    Lenses and accessories with no stopping groove must be screwed in
     until the index mark A on the lens and the red spot B on the camera     coincide.

  Close-ups
    ln addition to the focusing range of the renses, crose-ups up to an   image scale of 3:1 are possibra with supprementary renses, extension
   tubes and a bellows focusing device. Besides ail thl necessary tabres,
    12

the booklet of tables also contains a diagram showing the exposure
 ranges that can be obtained in this way. As the reduced depth-of{ield
 in close-up photography requires additional stopping down, which in
 most cases results in longer exposure times, the use of a tripod and
 cable release are recommended.
 ln this context, we draw your attention to our copying units REpRopHor
 1 and 2.

 Exposure measutements for close-ups
 only with pressed-in diaphragm stop-down pin 3 (working aperture
 measurement).  lf the extension tubes 1:4 and 1:1, the bellows focusing
 device, the Luminars or the micro-attachment are used, exposure mea-
 surement is in principle the same als described above.
 The exposure factors given in the booklet of tables for extension tubes,
 the bellows focusing device and the Luminars only apply when a sepa-
 rate exposure meter is used.

 Supplementary lenses
 with their bayonet fitting 0 B 50 they fit ail lenses available for the
 sL 706 from 35 to 135 mm. In order to obtain a sufficient depth-of-fietd,
 the lens should be stopped down to at least f/s.6. ft filters are used,
 these are to be mounted in front of the supplementary lens. special
 supplementary lenses can also be fitted to the Monocular gx30 B. The
 image scales that can be obtained in this manner are to be found in
 the diagram in the tables booklet. All other data are to be found in the
 instructions for use for this piece of equipment.

Extension tubes
The extension tubes extend the focusing range of the sL 706 up to an
image scale of 1 :4, 1 :2 and 1 :1 (especially advantageous when
copying slides). The given scales 1:4, 1:2, and 1 :1 are only appli-
cable, however, to exposures taken with the 50 mm lenses. These values
are not correct for other lenses.
The extension tubes are attached to the camera as already described
in the paragraph on changing lenses. The diaphragm stop-down pin must
not be depressed here either. In the same way, the lenses are attached
to the front thread mount of the extension tubes.
The possibility of pre-selecting the aperture or controlling the depth-of-
field with the pin 3 is not impaired by the extension tubes. The tubes
can, of course, be used in combination or attached to the bellows
focusing device. In the booklet of tables you will find an illustrated
chart showing all the possible combinations with the TESSAR 2.8/50 mm.
There is also a simplified table which shows the depth-of-field for the
set image scale. The exposurewww.butkus.uscorrection factors also included apply
when working with a separate exposure meter.

The bellows focusing device extends the scope of the sL 706 in the
 field of close-ups and macrophotography.  This unit makes  it possible'io
 take pictures at a slightly reduced scale, in natural size or on a magni-
 fied scale of reproduction. The bellows focusing device increases the
 distance between the lens and the film and thus sets the lens to a
 shorter distance than would be the case if the lens was attached
 directly to the camera.
 The 35 mm lens cannot be used with the bellows focusing device,
 because the subject to be photographed would then lie within the guide
 bars of the device.
 Assembling the components
 The focusing bellows device is attached to the camera in the same
way as the lens with its thread-mount  ring 35. The lens is also attached
 in this way to the bellows unit with the thread-mount 40. The dia-
 phragm stop-down pin must not be pressed in here either.
Should the camera not be exactly horizontal to the focusing bellows,
you can loosen the three adjusting screws in ring 35, using a screw-
 driver not more than 1.5 mm in width, until the SL706 is correctly
 aligned. Now re-tighten the screws.
Focusing
Focusing is carried out through the viewfinder by turning the left-hand
knob marked "DRIVE" of the focusing slide 38, whereby the lens with
 its focusing mount can also be used. The right-hand knob {LOCK)
serves to lock the focused setting if it is turned in the direction indicated
by the arrow.
Whenever possible, focus with the diaphragm open. lf it is closed, push
down the diaphragm tensioning lever 39. After tensioning,  it returns to
its initial position. The diaphragm stop-down pin on the camera must
not be pushed in during this operation, unless you wish to check the
depth-of-field, which is only possible, however, when the subject  is
brightly illuminated. Owing to the fact that close-up focusing by simply
extending the bellows can lead to difficulties, because extending the
bellows also involves a change in the subject distance, it is advisable
when using a tripod to use the tripod slide 36 for focusing. This permits
the SL 706 to be moved forwards or backwards with the focusing bellows
device whilst the bellows extension remains the same. Adjustment is
made with the right-hand knob (DRIVE), whilst the tripod slide can be
fixed in position with the left-hand knob (LOCK).
For technical reasons, the camera cannot be swung into an upright
position when attached to the bellows focusing  unit.
This adjustment must be made with the tripod head.

Exposure
Please take care, when adjusting the exposure meter, not to open the
lens aperture too wide, in order not to reduce the already small depth-
of-field even further. lt is betterwww.butkus.usto select a longer exposure time,  if this
is possible. There are 2 possibilities for making the exposure:
                                                                17

  Gare of the camera
   We recommend that from time to time the film guide track and film
     transport bearing of the ZEISS IKON SL 706, as well as the inside of
    the camera back should be carefully cleaned with a soft hair brush.
     (Attentionl Do not scratch the shutter blind while doing this!) Dust or
    threads on the focusing screen or mirror can be carefully removed
     with a soft hair brush when the lens is screwed off. Fingermarks on the
    surface of the lens and the viewfinder eyepiece should be carefully
    wiped off with a soft linen cloth. Dust particles must be removed before-
    hand with a soft hair brush.

   Serial number
    Every ZEISS IKON SL 706 carries on its base a serial number. Every
    lens also has its number. We advise you to make a note of these num-
     bers, so that you can establish your ownership in the case of loss or a
   m isunderstand ing.
